Exactly correct. As a digital signal processing expert, I deal with this situation every day. With modern antialiasing filtering, reconstruction algorithms etc higher sample rates does not matter. 16 bit vs 24 bit resolution only changes the effective signal to noise ratio the systems can support. 16 bit supports 65535 slicing levels. 24 bit supports 16,777,216 slicing levels. Hence 16 bit supports 96 dB SNR where 24 bit supports a SNR OF 144 dB.
Get yourself better listening devices. stop using cone and dome drivers with spindel spring coil and rubber etc suspention = high moving mass slow stop and start. .Go for stax lambda best or their top model 009 as far i know. i have stax lamda signature mk2 from 92 No dynamic earphone has been able to beat it. still working fine. real earpads and go for a prize that is more than when i got them new still.
Audiophile nonsense has entered the chat. If your amp didn't cost more than my house, and if the knobs aren't made of bubinga, are you really trying hard enough?
Audiophiles are like flat-earthists, they don't believe in phase cancelation and when you talk about a null test they say it was filmed on a set by Stanley Kubrick 😁
I will say though, one advantage of using higher bit depths is that it can save a take if you realize (too late) that one of the mics wasn't amp'd enough, and you can't take another take, having that lower noise floor, from what I've seen anyways, allows you to really amplify the signal in the mix without getting any noticeable noise. But admittedly, that is a pretty specific usage, that happens because of user error to begin with. (edit) the whole thing about audio being better when treated less preciously is precisely why people seem to prefer vinyls & tape, even in today's day and age, I work in digital graphic arts, and it's really the same, often in digital artworks you want to add 'noise' and irregularities into artwork, that usually always makes it pop more, and gives it character
Yeah, if you were to record a sensitive source at something crazy low, like -60dBFS or lower in 16 bit you could MAYBE run into noise floor issues. That’s an insanely low record level, so it’s unlikely to be a problem very often. But because of this unlikely possibility it is definitely a best practice to do 24bit when recording instead. That seems reasonable to me. But even 24 bit is actually overkill for that, because none of your analog front end can use 24bit’s 144dB of dynamic range. 20 bit probably would have worked just as well for this purpose, because that’s about where really nice analog gear is going to max out for keeping the noise floor down, but it’s no big deal either way. For consumer audio though? No way! :-) Even 16bit is probably overkill for all practical purposes. Hope that makes sense! -Justin
It's worth repeating, as you mention, that capture and delivery are very different things. For example, Zoom just released a sound recorder that records 32-bit float (the F2 lavalier recorder). The huge benefit of that is that it's impossible to blow out the recording as it doesn't peak at 0dB, and levels don't need to be set. You just hit record and you're golden. Once the sound is captured, that 32-bit float just becomes 32-bit bloat (you heard me). Recording headroom is just recording headroom. The end listener doesn't need to hear the empty headroom, and won't benefit one iota from doing so.
No, people always use Nyquist-Shannon sampling theorem to say you only need to sample twice the highest frequency you want to record i.e. in Audio you only need 40kHz. But did not understand the whole theorem. The theorem also said you need to multiple every sample to a infinite function call sinc function to be able to recover the same wave form. The important word is "infinite function". It is impossible to calculate infinite function because that would take infinite time. So you always need to stop some where just like when you use Pi. Higher sample frequency will make calculation many times near to "infinite function". So same DAC chip with same computing power suppose to have easier time with higher sample rate in theory.
I noticed when I converted some of my masters to mp3 the mp3 file sounded more scratchy bright than the same track with a 24 bit wav. It was noticeably different in the high frequencies. After some trial and error I eventually fixed the problem by applying a high cut filter to the inaudible high frequencies in the track. From this I surmised that these inaudible frequencies were being mapped to audible frequencies by the mp3 codec. I’m not saying that high definition audio is superior because it handles frequencies, but rather curious why this happens? Why does the mp3 dithering not handle the mapping more gracefully?
Excellent, excellent video explaining the trivial quest for high res. I've played with various rates in my DAW and have not heard differences. Now I understand why. Thanks, Justin; my hard drives appreciate you....
If you're a music listener, you're not going to hear an improvement going from 320 kbps MP3 to lossless FLAC. Save the hard drive space and invest in better equipment (headphones, amps, speakers, etc.)
I always record in 48 kHz/24 for two simple reasons. 1. All my gear supports 48 kHz, so whatever interface I choose to use it’s working with 48 kHz. 2. If the recordings will be used in a video I will have a perfect sample match. If you use 44.1 kHz with a 24 FPS video each frame will have 1837,5 samples, so if I cut both the video & audio when the grid in PT is set to frame the cut will be between two samples. This is avoided with 48 kHz. So, that’s my approach, I use 48 kHz for practical reasons, not audible.
Same for me, I work in 48 for practical reasons, the TV/media business works with this sampling rate and expect you deliver your tracks/stems in 48k/24b.
If you guys are that kind of person whose doesn't hear any difference between "Apple Digital Master" versus CD, you may be definitely deaf. Even from the former Mastered for iTunes quality, from the same AAC quality it DOES A BIG DIFFERENCE over CD quality. Why the people doesn't notice any difference? The MASTER it does matter at all.
You are right. There's not much a point for super Hi res other than selling really expensive gear to people who don't know any better. The one advantage I'm seeing is you have a lot of very affordable devices coming into the market which offer tremendous quality. I'm speaking of desktop dacs costing less than 200$. And current audio is getting way better than it was 10 years or 20 years back
Yeah, and here are two conceptual things that are often misunderstood: 1. There are no stair steps. Digital audio is entirely smooth, continuous, and analog once it goes through the low-pass filter. That’s the whole point of the filter, is it turns everything at the upper frequencies into pure, smooth sine waves, filtering out all the squareness (which are just the upper partials). 2. It only takes two samples to accurately reconstruct any given sine wave at or below that frequency, perfectly in terms of frequency, amplitude, and phase. Sine waves have a particular shape such that you can mathematically reconstruct the whole thing just from the two samples.
Bingo! You are exactly right. Either a given frequency can be reproduced perfectly at a given sample rate (minus some noise, which is determined by the bit depth) or it can’t be reproduced at all. It’s a bit of an all-or-nothing affair. Thanks for the comment, Justin
@@SonicScoop Thanks for the video! Clearly explained, and your 10-year challenge is exactly the kind of real-world experiment I keep using to point out how people really can't hear the difference (though I wasn't aware of yours until now).
What's misunderstood is anti aliasing/mirror effect requiring low pass filters which he mentions in this video, but doesn't go through much detail. If you pay attention he is staying that the mastering process could benefit for higher frequency rate on the recoding session in terms of having a easier time filtering high frequo based on equipment used and recording in higher bit rate gives you much more headroom so there is less likely clipping while recording. I think the majority of people missed the boat on this. In other words, if you actually record in a higher bit rate with higher frequency rates where higher frequency noise with high enough amplitudes could enter the mix and a higher chance of clipping, it would make a difference.
Very good summary, I totally agree!👍 Especially concerning our golden time of audio quality! Unfortunately I can't imagine what we can expect from future developments🤔. The great leaps in improving audio quality are behind us. But luckily we are now able to concentrate fully in our creativity without be concerned about quality - even at home! I remember recording on noisy tapes in the 80ies. Everything today was science fiction at those times (a DAW running on an tablet!!!)
Thank you for interjecting some reason and science into this area. On a somewhat related note, I've noticed that many people equate "pristine" audio with detail. But audio that is very revealing of detail is not necessarily perceived as musical or all that pleasing to the ear. (I came across at least one blind study that arrived at the same conclusion).
True. Witness the love of the sound of vinyl - which has a smaller signal to noise ratio than 16bit digital audio, has more stereo crosstalk, and changes its frequency response and harmonic distortion characteristics according to how far towards the centre of the disc the needle happens to be. Not pristine at all by comparison to digital audio, but people love it.
I'd like to point out a big missconception here: quality matters if it's higher or lower sample rate, the lower sample rate the lower the quality that is a scientific fact judging by how the quantization works. The big point that all seem to miss is that beyond 44.1kHz one would not be able to tell the difference and basically is pointless to have so much storage space spent for nothing.
Exactly! 22K is pipe dream for most people; most adults hear in the 10 - 16K range, dependant on age, and the music doesn't sound 'different' just because we've lost a few KHz here and there! If cymbals still zing, and ting like they should, then excessive high frequency recording is a waste.... I know in some circumstances that there are higher frequencies that work with others to give a certain order of distortion that resonate well (certain harmonics) that if missing would destroy the feel of the music and maybe even notes being played, but these are all recorded within the 'lowly' 16/44.1 redbook solution, so it's not an issue! As you say, storage space for needlessly high 'resolution' files is just pointless! I love good old analogue, but I also love my (well recorded/mastered) CD's... :-)
Great video. I’ve had the same concerns myself and you properly articulated why. The best ever hifi upgrade I did was buy a Nord One Up amp. This was a game changer for my PMC OB1s speakers. I have heard differences between formats but not in ABX tests. What I mean is the Linn 96/24 for example sound great but think the real reason is the the audience for these are people who care about music and the producers bother to mix the tracks well in the studio. i.e. don’t dynamically compress the music. Place instrument well etc. It’s not the format it’s the production. Madonna immaculate conception on cd sound just as “interesting” and alive as any 96/24 recording do.
I really appreciate you taking the time to explain this in a way a layman like myself can understand. I was finding myself obsessing a bit on trying to get these higher bitrates and it was frustrating. I am at peace now with how things truly work. Especially someone like me who listens to music on bluetooth!
This is a very fin topic. Someone should have a discussion with the hi-fi (consumer) industry about this and then with the audiophile listeners using converters at 768 sample rates when listening to lower sample rate files.
Thanks so much for clearing this up. A while ago I did the 320kbps mp3 vs wav test and could not hear a difference at all... With high grade converters and headphones! I thought my ears were to blame.
You are not alone! Being human is to blame, not your ears :-) Good on you for actually doing the blind listening test. A lot of people with surprisingly strong opinions on this never actually do that.
Listening to Spotify premium 320kbps Vs CD quality music (Tidal) is a big difference in musicality. I can EASILY hear the difference between the two. With lower end equipment though that detail that you gain may not be as obvious to your ears. Going back from Tidal CD quality and higher to Spotify premium actually sucks it's so noticeable
@@georgearrows7701 also remember that the sound coming out from your headphones/speakers is going to be affected by everything that it goes through between the source and the end point. So if your pc has a shitty DAC it will lower the quality, a worser power source will also affect it. And also, the mastering of the track will affect it too. Start a free trial on a hi-fi service and listen to some different tracks. Do a side by side comparison
@@zachunter2357 That's the thing. I am using a pretty expensive semi-pro interface (RME Babyface Pro) + pretty good headphones (Slate VSX) and don't really hear it. Anyway, I will do the comparison again because this has been bugging me for years.
Good talk. As a matter of fact, nothing touches say, a 2" Studer and a vintage Neve console. Of course also the old outboard gear. There's a reason for all the modeling algorithms of that vintage analog gear. Yes, analog has a "smearing". But, digital lacks some body that analog has. Meant to mention. There's nothing like the saturation sound of hitting 2" tape really hard.
Some good examples of that "tape hit hard" sound: "Best Friend's Girl" by the Cars, "Bicycle Race" by Queen, Both produced by Roy Thomas Baker. He would have the engineer hit the 2" 30ips master really hard and said 'if the recording head glows red, we have a hit.'
I wish I knew half of what you talking about. Really just wanted to know if I wasting money with tidal Master plan. If hi - fi would have been adequate. Or if I'm just imaging Spotify not sounding good from my system.. Last two mins most useful for me. Listen to what works for you. Sound advice
Well illustrated, on top of all that we should consider the frecuency response of microphones (good old SM57 does not go over 15 kHz), preamps, etc. Just saying,
Years ago, I was tracking thru 18bit motorola converters. I was dropping the teac four Trac drum tracks down to digital. I noticed it sounded much more like the tape in 24bit than sixteen bit my sampling rate was 44.1 in both cases. I learned 24bit is better for resolution. However I had to mix down to 16 bit digital in this case. My hardware could only handle 16 in the multitrack window.
I listen to MP3s on an almost 20 year old Zune with Beyerdynamic studio monitor headphones and the sound quality is flat out amazing. 44.100/16bit is more than enough to capture and reproduce sound that humans can hear and a good ripped Mp3 sounds nearly identical.
I was running this video in background, and that 15kHz startled me, I thought something was wrong with my head. Anyways, it was mathematically proven that you only need double sample rate of what your maximum recorded frequency is, and that would give you accurate reproduction. Any errors in audio are not likely and negligible. Search for Nyquist theorem. 44.1 sample rate can be used to reproduce frequencies up to 22.05kHz. Only a few people, if any at all, can perhaps hear that. Noise for dogs.
My argument for using 24 or 32 bit float is just headroom, I can record really quiet sources and then gain them up and compress the living shit out of them and the noise doesn't come into that audible range. For consumer side I go 48/24 because it is standard for video.
Higher sample rates introduce less latency when monitoring natively via the DAW. Once tracked at high sample rate for low latency, there is no need to introduce sample rate conversion, which will cause degradation.
I do a lot of sound design and multiple renders of audio. Stretching, bouncing etc and have recorded at 96k for the last 12 years for that reason. Also my clients want 48k almost 100% of the time so the conversion is seamless this way. I think some of the “myths” of higher SR are leftovers from when converters weren’t as good (maybe), like early aughts. But if you really wanna hear a marked improvement, get a master clock. That was an eye-opener. I run 96/24 with Lynx Auroras and a Big Ben-that’s enough! But this video gets into consumer habits, and listening-and I agree. CD is fine and I really prefer vinyl. But it’s apples and oranges comparing processing digital audio with delivery specs vs listening to music. My .02.
Absolutely, for sound design or sample libraries where you’ll be time stretching audio or pitch shifting down significantly, higher sample rates make sense. That’s one of the special cases mentioned near the end of the video. And if you’re working primarily with video, 48k there is the norm, so may as well deliver it that way instead of sample rate converting a 44.1 file. Thanks for the comment, -Justin
Ah I wrote this literally 1-2 minutes before that caveat, haha. I also agree with the many other attributes mentioned as to creating good recordings, or rather, the Things That Make SR And Bitrate Moot. Like bad preamps, oppressive, stark, reflective rooms, poor levels, and questionable choices-the list goes on!
Man, I'm 34 and I still use a tascam 4 track cassette recorder and a Alesis 3630 compressor for my music, and people that hear it don't tell me, nobody will like your music because it was recorded on a tascam cassette recorder and a Alesis 3630 compressor
Becuz: the resolution of good quality tape and agood cassette machine and analog outboard gear is better than a lot of digital stuff. Especially when you start using plugins.
Great point, also if the music is great all the techy things don't matter as much. LIke, what is the best mic? The one with a real artist in front of it. WHIle i've heard some crappy recordings done in garageband. I've heard some great stuff as well. Its more so the music, and the person turning the knobs.
Thank you Justin, this comforts me in my unashamed attitude of "If it sounds good, it's good"! I have a question about the "Air Band" on Maag plugins, I really like the "brightness-not-harshness" it allows my 58 years old ears to perceive and appreciate on instruments and mixes. I usually use 4-7dB @ 20k and only recently used 15k on the EQ2, should we be cautious of unheard frequencies causing aliasing generated by the plugin at 20 or 40k?
Good to hear! Aliasing should’t be a problem and should be filtered out if everything is working properly. But there’s a chance that to you get ears you might be boosting more HF than you realize :-) It could be good to double check things on a frequency analyzer to make sure the super high end you have trouble hearing doesn’t look to crazy relative to references. Either that or visit a high school classroom, draw your nails across the chalkboard to get their attention, and then ask them for feedback on your mix ;-) Hope that helps! -Justin
I think there is a better low bitrate formats than the mp3 like m4a aac, ogg, because the spectral analysis sometimes shows that some mp3 converters screw up the songs by cutting too much frequencies. So you still get 320kbps but in reality it's less.
I remember converting the black album cd in the '00 to various kbps mp3, starting from 32kbps to a variable which at that time was up to 220 kbps I think. And the sound depended a lot of the speakers. In the PC starting from 128 kbps sounded good, but in the hifi equipment to a properly bass sound must had be the variable, not less. Even if actual 320 kbps mp3 is said to be enough, I consider quality cd, be WAV, be FLAC, etc, the most honest format to sell music, just in case, the original, nothing removed.
Sounds reasonable to me! Though I understand why people don’t want 4x larger CD file sizes on their devices or streaming sites for practical reasons. -Justin
So, Justin, I see you've changed back to another JZ Mic which looks like the V67! Nice choice! As for the topic, I really enjoyed listening to this and your perspective. I have to admit that I was somewhat of a numbers-fan and thought that bigger meant better. However, after listening to you it made sense to me in that you really won't hear the difference on the listening end of the sound. And I'm convinced that you need some really high-quality headphones to even attempt it....if you can. I've tried and didn't hear a difference. I am going to have to do some really close comparisons when I do get a chance to see if I can capture the differences between the two resolutions. Again, thanks for this video Justin!
flac is lossless. A great mathematical data compression trick. I remember it translating even highest samplerates lossless in audio information. The rest I enjoyed a lot.
Love your content bro. I'm 28 years old and can hear clearly from 30hrz to 22khz. I tried many app from play store and that's my hearing rage. However that higher frequency I perceive them as noise.
Thank you. Your video helped me staying with Spotify for the UI, multi-platforms (Connect) and international songs selections. Honestly tried Apple Music and Tidal and just not getting any additional benefits.
Yeah, 320kbps is a pretty amazing consumer format. Improvements from there have routinely been shown to be existent in double blind listening tests, so whichever service you prefer for other reasons is probably the more important variable. Glad you found a choice that makes you happy! Very best, Justin
I use to bounce my music from Cubase (6) to a 44.1kHz/16Bit wave file, then drag it onto my iPod mini, go out to smoke a cigarette and gaze into the distance. It occured more than once to me, that I was bouncing out an 320kBps MP3 and was not aware of it. The funny thing is: That iPod makes it a blind test without my provision - it doesn't show or tell you in any way which format is being played back. BUT: My nearly 40 years old ears seem to reveal it - whenever I listen to one of my productions and I have the feeling it's not uncompressed sound... guess what: In fact it would be compressed, really. I would yet have to fail on that one to conclude an MP3 sounds just as good as a PCM. But don't get me wrong: I agree wholehartedly to what you say in this video.
Thanks for this post! I’d love to hear your perspective on apple digital masters, I feel like they sound better but I don’t know the engineering behind it.
One benefit of using 96 instead of 48 at recording is the AD converters allow me better headroom. Not sure how to explain this in technical terms other than what I see when I clip the sound at 48 compared to 96. Another benefit of higher sample rates is signal latency. Although I've never considered 96 being “super high resolution.”
Headroom and dynamic range is a function of a bit depth, and of the analog components of your converter. Sample rate just doesn’t play into it, in theory or practice. If your converter works differently at the two sample rates for some reason, that could be possible I guess. I’d like to know why. That seems like an odd design. But that seems unlikely. If anything, it could be slightly less easy to clip a lower sampling rate because you are dealing with less signal overall because the reduced supersonics and lower anti-aliasing filter. Have you done any properly controlled tests of this where you can absolutely confirm this is the case? Please share if you can! I’d be curious to know more. As I’m sure you sneaky know, we all think we hear things that we aren’t really hearing. It’s happened to all of us. I’m sure you’ve had the common experience of fiddling around with an EQ knob, thinking you were changing the sound subtly, until you realized it wasn’t engaged, or you weren’t on the right channel. That’s just part of being human. As powerful as we can develop our listening skills, it is true that our minds will always be more powerful still. If you have a test you can share that confirms this, I’d be very interested to see it. Thanks much! Hope that helps, Justin
@@SonicScoop Many thanks Justin! I noticed it when running outboard reverbs both at 48 and 96. At 96 I had more headroom before the signal clipped in the converter, RME ADI-8 DS Mk3 via ADAT to/from Apollo 8. So it was purely by eyes I noticed about signal not clipping at a certain level. Nothing else was engaged or changed so I was a bit surprised myself. Probably more to it than headroom being changed then : ) I'm like you-being aware of the sound while fiddling and thinking yup that's a tad better-and realising the plugin wasn't active : ) I have that perspective when listening to anything these days but trying to explain how the brain fools us is a difficult task but I'd be happy if you talked more about that, blindtesting, do we actually hear the difference we think we hear etc etc.
Try as I might I have yet to be able to hear the difference between cd quality and the high res audio, which could explain why sa-cds never took off. I’ll have to try the MP3 320k to see, but I know that at 256k I can tell but it’s really difficult.
You're sorta right and sorta wrong. When testing my fave synth at 2441 and 2496, I was shocked at the difference in clarity. Always good to start at the highest possible quality and then Downsville, if needed ... that's my 2 1/2 cents.
The other thing is that although we do have the best audio formats available to consumers now, they don't listen to music in any way to take advantage of them. Phone speakers? Laptop speakers? Alexa speakers? People aren't really even listening in stereo.
It’s true, people can listen on some pretty garbage speakers these days! But on the other hand, if they wanted to, really great sounding speakers and headphones are available at a much better fidelity and a much lower price than ever before in history. That’s kind of awesome. Let’s not romanticize the past too much either though. Back in the day, most consumers also listened on total garbage speakers and hardware, often as bad or worse than the laptop speakers of today :-) But people have very fond memories of listening to music on their terrible tiny old transistor radios, or even today on their phones and laptops or even a single shared earbud with friends. As cool as good audio is and can be, music is ultimately way cooler and way more powerful. Hope that makes sense, Justin
@@SonicScoop Hey Justin. You're right of course. Transistor radios were shrill and distorted. I inherited a basic little reel-to-reel machine when I was about ten, which only had one speaker (even though it was a stereo tape head). But then we also had a radiogram! The turntable in it ran at 33rpm (or less), not 33/3rd. I only realised when I took my albums over to a friend's house, and at first thought their machine was running fast. But everyone else's was the same, so it was our radiogram that was wrong.
I would somewhat argue against that, I would say that a lot more people have headphones that sound good, compared to how many people had good sounding headphones or stereo systems in the past. So while some listening, does take place on sub par playback equipment, a lot of people actually also listens to equipment that is far superior to the typical listening equipment just a decade or more ago. However, that is an issue, that mixing and mastering focuses so much on speakers rather than headphones, as most listening with quality equipment these days is actually with headphones, compared to the past when stereo speakers were the dominant listening environment of quality. This causes a lot of issues with the stereo representation, where speakers provide a channel crosstalk that doesn't exist in headphones, and the fact that we can't tell the direction of low frequency sounds in a room, but if if is only sent to one headphone we can.
This should be a mandatory lesson for anyone trying to understand digital audio. At least now I know I'm not crazy after reading the audiophile garbage everywhere. The marketing has gotten out of control & sadly pushes over taxed hardware basically to scam consumers. 32bit float @ 192Khz even for most science is insane, But if you need Auto Tune on every song "Go For it" Clearly cheaper than actual lessons on how to stay in key. In my experience going from 16bit to 24bit was a great improvement - Beyond that I can't tell the difference - at least not with a decent recording. Yet the Audiophile branding just keeps pushing the envelope "I think They-- They whom ever They are-- Have flown the koo koo's nest. The test of who's audio sweep sounds better than the next -- Great I'm 50 & still stuck hearing an 18 & 19 Khz whistle out of $10K speakers being sold as "THESE are the Golden Turd" VS my old Polk Audio's I've been mixing with for 30+ years. GTFO.... This vid IS true Factual Gold THANK YOU... Also helps be understand why the headphone market is so wacked as well.
@nicksterj Well the difference between 16bit & 24bit is a huge difference in the quality on guitar ad/da - Going from the 80's 16 digital crap compared to today is night & day. No one I know is jumping to drop their new Samplitube or Helix to grab a late 80's Zoom pedal because they can't tell the difference. There is an Absolute difference, But the jump to 32 bit isn't proving to have the same effect.
Well done on this video! I have been singing this same song for years on forums and with students. As a delivery medium, why do you need more than 100dB of dynamic range? (dithered 16 bit). The part I think many still struggle with, and I can see it in some of the comments here, is not understanding the bit depth of a session. (Speaking about Pro Tools here, but I believe other DAWs are similar). If set my session to 16 bit and fill it with 16 bit files, we are not operating in a 16 bit world. Every DAW these days has at least , a 32 bit floating mix engine. You are mixing and outputting a 32 bit signal IN SPITE OF THE FACT THAT IT MIGHT BE MADE UP OF 16 OR 24 BITS FILES. The bit depth of the session only relates to the bit depth of any files you record into the session or any files you import that require conversion.
I started as an engineer in the 80s. 60db headroom was about what we had. When the 16 bits came in no one could believe how low the noise floor was. All DAWs now have 32 bit internal buses and some even have 64 bit summing. No one seems to understand. I still deliver projects at 24 bits as otherwise, people don't think they are getting their money's worth. This is to make vinyl from lol
I have 100s of classical cds at 16 41k. The biggest difference I can hear is not in the quality of the amplifier, the DA converter, the headphones, the full tube amp, the toroidal transformer... It's in the microphones, mic placement, instruments, studio preamps and mastering. I do think a small difference is gained however in SACD.
i don't seem to hear anything above 16khz. when i was a boy having equipment that had frequency range up to 12khz was quite good. and everything sounded just fine - percussion etc. for example a sharp boombox. or a turntable with a built in amplifier. they sounded just fine.
Most of the difference to music quality appears to be down to the recording and mastering process, in my personal experience. While 320 kbps MP3 might be hard to distinguish from 16/44.1 FLAC... I wonder whether that's not really dependent on the hardware to a good degree. The better setup, the easier the perception of transients and hence space, distance etc., might be. I can for sure tell that the quality difference between streamin of something lossy like through Spotify versus lossless like through Tidal, is night and day, in clear favor of the latter. That is though probably also mostly due to Tidal sourcing the tracks much better. I've been custom-upsampling (like 64M taps sinc filter using SoX) my FLACs to 24/96 (for my phone) and 24/768 (for my home setup) because it gives me a bit more refined, clearer and smoother highs, which I actually hear the difference in (although the differences are kind of subtle, they won't really hit one in the face), and that's comparing FLACs, and even that on mid-fi equipment, nothing that breaks the bank. MP3 is really out of the picture there. Sorry for not having done the double blind test experiments! Will for sure try that though.
Also, today's delta-sigma DACs and even some other DAC tech like R2R tend to oversample themselves, unless you supply them a high-enough input stream. Save for Rob Watt's M-Scaler or something in that league, the small chips of these DACs that need to do their resampling in real time can't really compete with an offline process that takes a few minutes per track on a modern CPU core and a good 6 GB of RAM to finish... And another very clear benefit of oversampling to mention is that today's music that gets released is most often overly loud and already digitally clipped, which means informations is already lost in there, mostly impacting the higher frequencies. A proper upsampling process (after digitally lowering the volume beforehand, sometimes by as much as a whole third), can reconstruct the waveform and partially undo the damaging effects of digital clipping. Perhaps it is this that justifies the oversampling hassle to me, since the space storage and the bandwidth between my home NAS and my living room computer doing the audio playback, is not really an issue.
Hey man SUPER VIDEO !!! I thought how strange he says a frequency and I hear it, it is early in the morning and while enjoying a cup of tea and coffee I first listen to EWF Shining Star, All About Love, Yearin Learin, at a low volume level , to also train my hearing .. and check where Mick Guzauski pops up .. but yesterday this video of you also put my checklist ... ha ha ha I thought I can hear it well played back 3x yesss I hear it everyone ;-) thanks for the unconscious test.
Here is a blind test that will change your mind, Justin. Listen to a 320k vs. a wav or flac (create both from the best same source) of The War on Drugs' "Lost in the Dream." I have, and for a fact, I can tell you there is a specific character that shows the difference. I challenge you to notice it, it can be deciphered in the first minute of the song. Another stunning mix was Morning Phase, equally decipherable. The sense of detail and SPACE that is destroyed by 320k is obvious to me, at least. Most won't notice, so don't stress, that is true. But when you personally want the best, why not go ahead and mix for that. Try to hear it, try to make it.
Interesting to hear! What are you using to listen to the these properly double blind? I can tell you that I have had similar experiences in sighted listening tests. For instance, when I created a similar listening test for our readers, I could have sworn up-and-down that I could hear the difference when listening sighted, and that so many people were going to get it right. But as soon as I properly jumbled them up so I didn’t know which was which, those differences seemed to evaporate like a mirage. Ultimately, the results of thousands of responses to our online test were no better than chance: www.trustmeimascientist.com/2012/04/02/take-our-audio-poll-do-we-need-higher-definition-sound/ If you can consistently distinguish this, that would be amazing! No one in the world as of yet has been able to show that they can consistently distinguish between 320kbps and any higher resolution format in a proper double blind listening test. I’m not saying that it can’t be done. Just that it never has been yet on record. If you can do it, that would be amazing. I’d happily write a glowing full length article about you and how you are able to do this so we can share it with the world. I’ve had this challenge out for almost a decade now, and so far no one has done it yet. It would be awesome to finally put a bow on it. What software or hardware solution are you using to do proper double blind listening tests on your end? Is it an ABX tester? That could do the trick. Thanks, Justin PS: Here’s the original challenge on my old blog. It’s been seen tens or hundreds of thousands of times, shared all around forums and all that, but no luck yet! Be our champion :-) www.trustmeimascientist.com/2013/09/03/think-you-have-golden-ears-take-the-scientist-challenge/ www.trustmeimascientist.com/2013/10/07/update-on-the-golden-ear-challenge-who-will-conquer-audio-mount-everest/
@@SonicScoop Well I went, prepared to be humbled, but the links for Line 'em Up and Kite of Love are broken. I did find in another of the articles the foobar can have an ABX tester plugin, I'll do that. My previous tests had my wife switching the tracks; a program that does that will be fun, so thanks very much for that. Also, please know I meant no disrespect, I love your channel and learn what I can from it :)
320k MP3 isnt a "hi res" format - its still a compressed (althogh half decent) file. Im pretty sure Justin is referring to higher sample rates and bit depths.
To me... Other than Sample Libraries or Bats... The Higher Sample rates are best for Audio Restoration where you are capturing Archived Media... and Forensic Audio
Last week I switched to high sample rate for my mixing template. Not for that "super high quality" sound (actually when the files were recorded at 48kHz than they CAN NOT be converted to higher samples rates with all that extra information) but for the digital processing I use. Some of them have oversampling but some simply don't. And those plugs which don't have oversampling CAN achieve a more accurate harmonic saturation/distortion. It depends on how well the plug-in was coded. So the sampling rate of my project is high but my exported file is still 16Bit 44.1kHz/48kHz. The only downside is the processing power - but hey with this "trick" you convince yourself using less plug-ins 😉
If it works for you keep on doing it! I would suggest that you eventually do an experiment though, just for fun and certainty. Try this: Bounce your mix from your 48k session. Then, copy your entire session from 48K to 44.1 K. Then, bounce that otherwise identical mix as well, to the same bit depth and sample rate. Now, load both up into an ABX tester and see if you can hear the difference! This would be one way to confirm that you were actually getting the benefit you hope you are getting. Maybe you are, maybe you aren’t. I don’t know! I have recommended this to a friend who worked at 88.2, and they have found that they couldn’t tell the two files a part. In some cases they stop using 88.2, in some cases they didn’t. But in no cases so far did they hear anything like the kind of difference that they thought they would. Maybe your situation will be different. In either case, if you try it, please share the results here! A lot of people would be interested to hear them I think. Thanks and I hope that helps! -Justin
I downloaded audio from a song posted to TH-cam and then listened to the CD version of it a few months later. I was shocked how some of the percussion sounded very clicky on the CD and warmer on the mp3! I’m not sure what YT does to the audio when uploaded but it definitely didn’t make it sound bad ☺️
TH-cam probably removes more high frequencies than is needed, especially with its standard resolution videos, which often have bitrates as low as 128kbps for sound. Unfortunately, they don't offer any 320kbps audio that would be indistinguishable from any higher resolution. Their 256kbps versions, which can only be found on their HD videos, is not bad at all, but the codec is not as good as those from other audio focused sites from what I have found. Unfortunately, I doubt that you downloaded even the 256kbps file from whatever sketchy side served up the download, so you could be missing a lot more high frequency in the YT download than is ideal. Go check the file and let us know what bitrate you got. I'm guessing maybe 128kbps? Hope that helps make sense of it! -Justin
Great video and description of the whole high sample rate argument and how it reflects to the quality of the sound. It also explains why my interface sounds better at 48khz and up. There is an endless thread on GearSpace on the whole subject.
i can notice the difference between mp3 320 and the cd track via a RME dac and monitor audio pl200 floor standing speakers ,only very slight differences ,because i listened to the Cd ,i prefer it ,otherwise if I just have the mp3 file ,i wouldn't complain .
End consumers getting the file in the same format it was recorded/mixed avoids a Sample Rate Conversion, which can mean less degradation. Higher sample rates give a more accurate trace of the analog/electrical wave form.
If you want to avoid sample rate conversion, don’t use the unnecessarily high sample rate to begin with :-) As far higher sample rates “giving a more accurate trace of the waveform”, I’m sorry but this is incorrect. That’s the exact misconception that we start off the video with, on purpose. There is just no mechanism in physics by which increasing the sample rate can do anything except for increase the highest frequency you can reproduce. It’s a bit of an all or nothing affair: Either a given frequency can be reproduced perfectly at a given sampling rate, minus some noise (which is determined by the bit depth) or it can’t be. This can be confirmed for yourself with proper testing. Similarly, there is no mechanism by which increasing bit depth can do anything but lower the noise floor. If you believe that there is, that would be an amazing breakthrough discovery and science! I mean, could you explain the mechanism by which anything else could occur? I hope that helps, Justin
@@SonicScoop when you have more samples per second, there is less rounding going on as the digital waveform tries to approximate the analog voltage (input). A hypothetical infinitely sample rate would track the voltage perfectly, to the atomic level or beyond. There would be no rounding, at that point. Its calculus. Approximation of a circle using discrete values. More "steps" equals a closer approximation to the continuous curve. Why not use less noise, noise is not typically desired. Even if not audible, it has interaction with the audio. There is no universal reason to not be technically better. If for no other reason, than archival purposes. If you null test an mp3 @ 320kbs, and a 24/96 file, there is no residual sound? Interesting discussion. -Kyle
@ReaktorLeak im talking about the capture at the ADC stage. Voltage to binary. A "perfect" conversion would track the voltage fluctuations down to the electron. Otherwise your missing information at conversion. ie the information that would otherwise be in between samples, is not recorded, it is ignored, the waveform jumps to the next discrete value, the analog signal is continuously variable. Up to the limits imposed by the hardware. Trace the outline of a circle with straight lines, once with 1" lines, another with 1/4" lines. The shorter more frequent lines give a "truer" representation of the circle. This is akin to sample rate. More samples, more accurately traces the voltage functions aka the analog audio waveform.
@ReaktorLeak you cannot recreate the circle however, because samples are discrete values (straight lines) in your example you would have a triangle. The samples cannot reflect the "inbetweens". The voltage change happening in between samples. "Reconstruction" of the inbetweens ends up in averaging. You don't "know" the voltage fluctuations, your guessing them based on the two points. A momentary transient occuring between two samples, would be ignored. It would go undetected, and get rounded/averaged away. The samples can't dectect things in between samples. They are akin to steps, not curves. Calculus shows us that more discrete values (samples) more accurately trace a curve than less. Its just like frame rate in video. 29fps is fast enough to fool the eye, until you slow it down. Higher frame rate is always truer to continuously varible.
@ReaktorLeak you can perfectly re-create the circle IF know ahead of time its a circle. If you do not know its a circle it could be any possible configuration of lines between those 3 points. A converter doesn't "know" the voltage fluctuations in between samples.
Its NOT just about what frequency you can hear up to. If you can't hear it your equipment might not be up to snuff, or youtube, or BG noise is masking the sound. This discussion totally ignores the psycho-acoustic dimension as well as harmonic granularity.
I’m sorry, but that’s just not correct. That’s the exact misconception that we start off the video with, on purpose. There is just no mechanism in physics by which increasing the sample rate can do anything except for increase the highest frequency you can reproduce. It’s a bit of an all or nothing affair.

Justin, loved it. Three questions: . A famed producer (I believe it was Aerosmith's producer said that excessively high resolution audio was allowing us to hear details in the original recording that weren't there and therefore were a bad thing. True/false? . Jimmy Page said the Zeppelin catalog was recording at such fidelity it's future-proofed for years (or more to come). Page specifically said for future "higher audio standards," which as they're in the future don't yet exist. True/false? . I thought the sound on VHS was/is pretty groovy. Isn't VHS tape a NON digital format? Hence, the sound is 16 bit which as you noted no one can really distinguish from 24 bit. Hence, analog can reproduce in the instance of VHS sound as close to the source as digital? Not a trick question. P.S. I think one big misconception you blew-up in this video, is that if you record say, a giraffe making a sound at a zoo - whatever sound they make at 16 bits and you record it at 32 bits - most folks, including many professionals, believe that at 32 bits of 'resolution' you'll hear greater fidelity with 32 bits. You'll hear a better sounding giraffe, as well as the sound of garbage rustling on the ground. A better wind sound. Maybe human speech, better, from visitors to the giraffe enclosure.
Yes, I think those first two examples come from a misconception about how this stuff works. There are a lot of people who are great musicians, producers-and in some cases, audio people-who don’t really understand the situation fully. They usually have never done double blind trials on any of this, and often don’t exactly understand what’s going on under the hood. But that’s ok. They can be tremendously great at what they do and be mistaken about this. I was once. Jimmy Page is an amazing guitar player. That doesn’t mean he knows how digital audio files work, or that he’s done blind listening tests at various sample rates or bit depths. That’s not really a criticism. You don’t need to know any of that to be a great musician, or even a great producer or mixer. If you had to pick between being amazing at guitar or production and knowing how digital audio works, the first too are way more badass :-) VHS CAN be digital (see ADAT) but is usually analog yes. (Technically you could record digital signals on a reel to reel take machine, and some companies made such machines early in.) But yeah, generally analog in both cases without getting too nerdy about it :-) Analog formats actually have lower dynamic range and higher noise floor than 16 bit. Good vinyl would be the equivalent of about 11 bit in that regard if I remember correctly. I’d imagine VJS would be around there or lower in effect, but I don’t know right offhand. Generally speaking, any analog formats are going to sound less like the source than a 16/44.1 file. The only thing that comes close is an absolutely excellent tape machine running at 30ips. That might come close to sounding as close to the source as any reasonably well built 16/44.1 system, and would be orders of magnitude more expensive. But analog can sometimes sound damn COOL, even if it doesn’t sound exactly like the source. A less than stellar tape machine running at 15ips could sound more badass than the original source. That’s subjective. But it probably won’t sound as close to it as even a basic stock AD converter built into a laptop. That’s objective. Hope that helps, -Justin
I find the only benefit of hi-res releases are that the albums normally receive a better mix, Metallica's Death Magnetic is a great example... the retail CD is a brick walled mess victim of the loudness war and due to the compression it's actually tiring to listen to it, the 24bit/88.2khz hi-res release just sounds better due to the mix and lack of compression, so I just converted the flac files to 16bit/44.1khz and burnt myself a CD that sounds better than the one I parted with cash for..
Yes, that is a valid reason to repurchase etc. It's a shame however that people are being convinced they should buy because of the numbers and not because of the fact you get a better mastering or better recording. If you convince everyone it's the numbers that matter, they will rebut every CD ever owned by them and it also attacks the second hand market. Imagine reprinting a book and encouraging everyone to rebuy because the new print has a HD font that will improve your immersion in the text.
Done quite a few tests and there are subtle differences in the amount of air or silence you hear in great audiorecordings in CD quality compared to compressed mp3s or AUCs leading to better separation of instruments. This is more apparent the more the file is compressed where reverb or room tails disappear. Lossless compressed sounds like CD quality even through good DACS(use a RME babyface). I cant hear any difference in quality beyond CD quality. The differences people hear is most likely technically related…some ADDAs just record and play back more reliably than others. So in all I completely agree, going beyond CD sound quality is just a waste!👍
@nicksterj MP3s didnt exist when the debate about digital vs analouge sound started. First time I heard it was with the arrival of the CD format. The whole record industry went bananas trying to quickly digitize their music catalouge to cd with varied success. As you say, a well mixed album and mastered(this is something you really did to fit the dynamic limitation of an LP). Unfortunately almost all popuplar music today is compressed, autotuned, grid quantized and overmixed to death in the loudness war….
@nicksterj saw the resurgance of vinyl already in the 90s, but now its bigger than in a long tume. Same thing happenings ng with film cameras for example…..guess its just how thingswork. Off course the motivation will be something like sounds better, better colours, better control over gear. Dont know if you followed the development of syntesizers, it has just come around to be back at the 70s…..people search for differnt stuff and are nostalgic at the same time.
@nicksterj I didn’t say that the sales of LPs were high in the 90s, there were plenty of used record stores. Many artists started to release LPs again way back early 2000s and there have been a small audience buying these as collectables. And you are right, now it has exploded, its common to be 20-30 something owning a record player….most wont argue around sound quality…..they just keep it next to their vintage camera and dumbphone.🤣
@nicksterj there were quite a few stores popping up close to Carnaby street London very early, were completely surprised that people even cared at the time, it might be that memory plays me and this was early 2000s...seems sales really took off again mid-late 2000s in many countries with a peak in the 2020s in according to wiki. On the jazz scene it's pretty common that the artists bring their Vinyls these days. Not so strange when there is simply no revenue at all from streaming services....
This is super interesting Justin. It means I can start a 44khz project in my DAW instead of a 48khz one and use the CPU and RAM saved for distortion, analog emulation, etc to make it all sound more interesting. My main concern would be the Nyquist frequency: when using certain plugins that may not have a resampling option, working at 44khz would be worse than doing so at 48khz as some artifacts would be more noticeable and hard to clean up? Thanks a lot for this episode!
Oversampling is needed only to reduce the aliasing caused by plugins that can introduce harmonics, so saturators, clippers, brickwall limiters, fast compressors etc. Working at 48KHz doesn't really get rid of aliasing at all, you always need oversampling to do that anyway: if harmonics are introduced to a 15KHz sine wave, in instance, the harmonics produced will be 30KHz, 45KHz, 60KHz, 75KHz, 90KHz, 105KHz etc and that's just up to the 7th harmonic and 192KHz would not be enough anymore so you need to have a sample rate that allows those harmonics to be correctly described. Whatever harmonics go beyond the Nyquist frequency are mirrored back below the Nyquist frequency. In instance, if you're working at 48KHz and you use a non oversampling saturator on a 15KHz sine wave, the 2nd harmonic will be 30KHz, and it will be mirrored back and appear at 18KHz (30KHz - 24KHz = 6KHz, and then 24KHz - 6 KHz = 18KHz).
That would be amazing! No one on the planet to date has yet been able to show that they can consistently distinguish between 320kbps any higher resolution format in a proper double blind listening test. I’m not saying that it can’t be done. Just that it never has been yet on record. If you can do it, that would be amazing.

@@SonicScoop when I DJing electronic music on radio, quite loud, I felt that wav was more punchy. I remember John Digweed said it too but he's one of the most respected DJ on earth (the first guy who released a DJ mix in cd with Sasha) he play on the biggest systems. When it's techno and playing loud, it seems to me to be punchier, clearer, cleaner . But maybe you are right I'm the wnner asshole's cup. It was when I was 25, maybe today I would not see the difference. Thanks for this video.
This theory is true with speakers mind. I tweeter able to go to 30k or 40k plays the 20k better because 20k is now not right at the physical throttle of 20k because it will begin to drop off at the point before stopping. Although that theory only counts if that is the purpose of the tweeter hitting above 20k. Physically it does give it space. It's why 3 ways and above do a better job... But that is there being more speakers handling less spectrums at the sametime. This a phycical thing so the diffrence does lay in this... the audio is best to not go above 20k even though they can handle more. There can be a diffrence in headroom with audio coming back in from highend analog equipment but not going out into it. With that said the diffrence is so little that the complication of downsampling that afterwards is kind of pointless. Consumer products are focused on going out which is pointless sending out anything over 20k. There is a diffrence with some plugins mixing down to two channels but then again the diffrence here is the sound you are looking for. There's a gain in the sound of analog emulation plugins (some of them, not all of them), but going out to analog in a high bit rate doesn't make sense. So I would bounce each track that is better in a higher bit rate then turn down the bit rate to 48 to go back out to analog. That is a bit of a headace though for such a tiny diffrence but that would be good for anyone with no real analog equipment. But when it comes to the resolution at the end... then 44.1 and 48 is more than enough. I stick with 48 due to the flexibility with video This was a video with bits I hadn't thought about before that really relly helped me re remeber things and add a little extra in those thoughts
So, 24/48 as a standard. 32/96 for post-production RX, if necessary (the elimination of digital distortion). Eh???? I suppose the only thing that comes to mind is the air at the top for 3D resonance (psycho-acoustics?). Having a 32/96 interface, causes me to ask, why not? I get the file size argument, but being that the end product is going to be crushed by the streaming services, why not produce at the higher rates as an offset to the crushing that is going to occur on Spotify, etc. I am fine with 24/48. Really, the only real argument remains the file size within the production computer. Thanks for the emotional battle I now have to have with myself. Yeah. And you did just blow that lunch date with Neil Young. Thanks for always giving me so much to think about!!!
I'm going to simply trust my ears, I can hear the massive differences between speakers, and headphones of course, and yes my two external DACs do sound different to me (not one better than the other, but different). But can I hear the difference between high resolution audio and standard resolution music? No, I can't! So basically I don't care, standard works amazingly well for me. I heard the 14KkhHz but not the 15.... I'm in my late 40s.
We all can perceive above 20khz There’s a new reasearch that shows activity in the brain. The activity is where the brain perceives localization The test was conducted with 20khz to 100khz and also most of the 66 participants preferred the music with ultrasonic content
Are you talking about a study from Japan in the 1990s, in which there was a potential preference for one piece of music (gamelan chimes) based on subjective readings of brain scans, but for none of the other pieces of music in the test? That same single study from the 1990s with flawed methodology, dubious conclusions, which found no difference for all other musical selections, and which has never been replicated? If it’s something other than that, please let me know! 🙃
Genuine question. I heard somewhere that 96k is a requirement for film sound/music. 1. Is that true? 2. What benefits (for film) does it give to have audio in such high resolution?
48K tends to be the standard in video production that is used most commonly in my experience. This is mostly because the math works a little bit better between 48K samples and 24 frames per second. That way, you always have an even number of samples for each frame. That’s pretty much why that standard was adopted. Hope that makes sense!
I use Wave 48K at 32 float because I believe if I yell too close to the mic, and it goes way into the red by accident, it won't distort. When I export to MP3, it still sounds good. Am I wrong?
I've been saying for quite a long time, anything beyond 24-bit 48kHz (chose this really only because it's what you'd see on DVD's and Blu-Rays) is useless outside of production environments.
this is AWESOME! next time I'd love to hear some peak compression on your voice to make things just a bit more audible :) also, my cat looked at me funny when I unmuted the video at around 8:45 😹
Usually there is a whole chain of compression, limiting and EQ on the voice, but there was a glitch with Premiere' s export where none of it actually got printed. By the time it was uploaded, getting thousands of views and discovered, it was too late to change it 🤷 TH-cam doesn't allow you tor replace audio or video unfortunately. Ironically, the only complaints about this video's audio quality is that we didn't degrade it ENOUGH by making the audio less pure with tons of compression, EQ and limiting. Kind of shows what really matters in audio. In a literal sense, this uncompressed and untreated audio is more "real" and "high fidelity" than a voice that has gone through normal amounts of audio treatment for this kind of format. -Justin
I'm 55 years old, and greatful that I can hear 14 kHz
I’m 55 too and glad that I hear around 15kHz ( left ear 14+kHz Rt Ear) 🙏👍
I'm 43 and I'm glad I'm fine at 14 khz as well
At this point, we just have to put on a high shelf and hope for air that isn't killing the young 'uns :)
Yeah I think mine cuts out around 13khz
Roughly same age, 57, and about 14kHz too (actualy 14khz for the right hear and 13,5 for the left one).
Exactly correct. As a digital signal processing expert, I deal with this situation every day. With modern antialiasing filtering, reconstruction algorithms etc higher sample rates does not matter. 16 bit vs 24 bit resolution only changes the effective signal to noise ratio the systems can support. 16 bit supports 65535 slicing levels. 24 bit supports 16,777,216 slicing levels. Hence 16 bit supports 96 dB SNR where 24 bit supports a SNR OF 144 dB.
And then add noise shaping to that dither and the effective SNR of 16bit goes up to 120dB.
Get yourself better listening devices. stop using cone and dome drivers with spindel spring coil and rubber etc suspention = high moving mass slow stop and start. .Go for stax lambda best or their top model 009 as far i know. i have stax lamda signature mk2 from 92 No dynamic earphone has been able to beat it. still working fine. real earpads and go for a prize that is more than when i got them new still.
tweeters air motion transformers are the way(AMT) and planar magnetic mids.with sensitivity at 96 db pr1w 1 M smashes most old school type drivers
Audiophile nonsense has entered the chat. If your amp didn't cost more than my house, and if the knobs aren't made of bubinga, are you really trying hard enough?
Audiophiles are like flat-earthists, they don't believe in phase cancelation and when you talk about a null test they say it was filmed on a set by Stanley Kubrick 😁
So sony is just a fraud? Apple music also? Ok im gonna throw all of them in the garbage can. Thanks to you.
It's so refreshing to watch this.. logical, sensible, reasoned advice. Thank you!
I will say though, one advantage of using higher bit depths is that it can save a take if you realize (too late) that one of the mics wasn't amp'd enough, and you can't take another take, having that lower noise floor, from what I've seen anyways, allows you to really amplify the signal in the mix without getting any noticeable noise.
But admittedly, that is a pretty specific usage, that happens because of user error to begin with.
(edit) the whole thing about audio being better when treated less preciously is precisely why people seem to prefer vinyls & tape, even in today's day and age, I work in digital graphic arts, and it's really the same, often in digital artworks you want to add 'noise' and irregularities into artwork, that usually always makes it pop more, and gives it character
Yeah, if you were to record a sensitive source at something crazy low, like -60dBFS or lower in 16 bit you could MAYBE run into noise floor issues.
That’s an insanely low record level, so it’s unlikely to be a problem very often. But because of this unlikely possibility it is definitely a best practice to do 24bit when recording instead. That seems reasonable to me.
But even 24 bit is actually overkill for that, because none of your analog front end can use 24bit’s 144dB of dynamic range.
20 bit probably would have worked just as well for this purpose, because that’s about where really nice analog gear is going to max out for keeping the noise floor down, but it’s no big deal either way.
For consumer audio though? No way! :-) Even 16bit is probably overkill for all practical purposes.
Hope that makes sense!

Neil Young and Robert Fripp are suiting up for battle.
Now FRIPP on the other hand.....
They're delusional.
It's worth repeating, as you mention, that capture and delivery are very different things. For example, Zoom just released a sound recorder that records 32-bit float (the F2 lavalier recorder). The huge benefit of that is that it's impossible to blow out the recording as it doesn't peak at 0dB, and levels don't need to be set. You just hit record and you're golden. Once the sound is captured, that 32-bit float just becomes 32-bit bloat (you heard me). Recording headroom is just recording headroom. The end listener doesn't need to hear the empty headroom, and won't benefit one iota from doing so.
No, people always use Nyquist-Shannon sampling theorem to say you only need to sample twice the highest frequency you want to record i.e. in Audio you only need 40kHz. But did not understand the whole theorem. The theorem also said you need to multiple every sample to a infinite function call sinc function to be able to recover the same wave form. The important word is "infinite function". It is impossible to calculate infinite function because that would take infinite time. So you always need to stop some where just like when you use Pi. Higher sample frequency will make calculation many times near to "infinite function". So same DAC chip with same computing power suppose to have easier time with higher sample rate in theory.
I noticed when I converted some of my masters to mp3 the mp3 file sounded more scratchy bright than the same track with a 24 bit wav. It was noticeably different in the high frequencies.
After some trial and error I eventually fixed the problem by applying a high cut filter to the inaudible high frequencies in the track. From this I surmised that these inaudible frequencies were being mapped to audible frequencies by the mp3 codec.
I’m not saying that high definition audio is superior because it handles frequencies, but rather curious why this happens? Why does the mp3 dithering not handle the mapping more gracefully?
Probably a bug in the mp3 encoder, maybe they are resampling the audio using a naive averaging algorithm
My dog has been upsampling my music. I am pissed.
Excellent, excellent video explaining the trivial quest for high res. I've played with various rates in my DAW and have not heard differences. Now I understand why. Thanks, Justin; my hard drives appreciate you....
If you're a music listener, you're not going to hear an improvement going from 320 kbps MP3 to lossless FLAC. Save the hard drive space and invest in better equipment (headphones, amps, speakers, etc.)
All my music is “mixed for bats 🦇”... “can I have a dollar now?” 😎
I always record in 48 kHz/24 for two simple reasons.
1. All my gear supports 48 kHz, so whatever interface I choose to use it’s working with 48 kHz.
2. If the recordings will be used in a video I will have a perfect sample match. If you use 44.1 kHz with a 24 FPS video each frame will have 1837,5 samples, so if I cut both the video & audio when the grid in PT is set to frame the cut will be between two samples. This is avoided with 48 kHz.
So, that’s my approach, I use 48 kHz for practical reasons, not audible.
Valid reasons for sure!
Same for me, I work in 48 for practical reasons, the TV/media business works with this sampling rate and expect you deliver your tracks/stems in 48k/24b.
If you guys are that kind of person whose doesn't hear any difference between "Apple Digital Master" versus CD, you may be definitely deaf. Even from the former Mastered for iTunes quality, from the same AAC quality it DOES A BIG DIFFERENCE over CD quality. Why the people doesn't notice any difference? The MASTER it does matter at all.
I record in 47.924khz at 23 bit, send it to you and dont tell you about it
@@JnL_SSBM Yeah. That's the masstering, not the sampling rate or bit depth.
You are right. There's not much a point for super Hi res other than selling really expensive gear to people who don't know any better. The one advantage I'm seeing is you have a lot of very affordable devices coming into the market which offer tremendous quality. I'm speaking of desktop dacs costing less than 200$. And current audio is getting way better than it was 10 years or 20 years back
Brilliant. Anybody interested in music should watch this.. and understand it.
Yeah, and here are two conceptual things that are often misunderstood:
1. There are no stair steps. Digital audio is entirely smooth, continuous, and analog once it goes through the low-pass filter. That’s the whole point of the filter, is it turns everything at the upper frequencies into pure, smooth sine waves, filtering out all the squareness (which are just the upper partials).
2. It only takes two samples to accurately reconstruct any given sine wave at or below that frequency, perfectly in terms of frequency, amplitude, and phase. Sine waves have a particular shape such that you can mathematically reconstruct the whole thing just from the two samples.
Bingo! You are exactly right.
Either a given frequency can be reproduced perfectly at a given sample rate (minus some noise, which is determined by the bit depth) or it can’t be reproduced at all. It’s a bit of an all-or-nothing affair.
Thanks for the comment,
Justin
@@SonicScoop Thanks for the video! Clearly explained, and your 10-year challenge is exactly the kind of real-world experiment I keep using to point out how people really can't hear the difference (though I wasn't aware of yours until now).
@ReaktorLeak Great example!
@ReaktorLeak Thank you for this analogy👍
What's misunderstood is anti aliasing/mirror effect requiring low pass filters which he mentions in this video, but doesn't go through much detail. If you pay attention he is staying that the mastering process could benefit for higher frequency rate on the recoding session in terms of having a easier time filtering high frequo based on equipment used and recording in higher bit rate gives you much more headroom so there is less likely clipping while recording. I think the majority of people missed the boat on this. In other words, if you actually record in a higher bit rate with higher frequency rates where higher frequency noise with high enough amplitudes could enter the mix and a higher chance of clipping, it would make a difference.
Very good summary, I totally agree!👍 Especially concerning our golden time of audio quality! Unfortunately I can't imagine what we can expect from future developments🤔. The great leaps in improving audio quality are behind us. But luckily we are now able to concentrate fully in our creativity without be concerned about quality - even at home! I remember recording on noisy tapes in the 80ies. Everything today was science fiction at those times (a DAW running on an tablet!!!)
Thank you for interjecting some reason and science into this area. On a somewhat related note, I've noticed that many people equate "pristine" audio with detail. But audio that is very revealing of detail is not necessarily perceived as musical or all that pleasing to the ear. (I came across at least one blind study that arrived at the same conclusion).
True. Witness the love of the sound of vinyl - which has a smaller signal to noise ratio than 16bit digital audio, has more stereo crosstalk, and changes its frequency response and harmonic distortion characteristics according to how far towards the centre of the disc the needle happens to be.
Not pristine at all by comparison to digital audio, but people love it.
@@latheofheaven1017 Great points.
The fact that you had no uptake on your listening challenge from 10 years ago is very telling.
i agree about your main point, but i can definitely hear the quality difference between full cd and 320kb mp3.
I'd like to point out a big missconception here: quality matters if it's higher or lower sample rate, the lower sample rate the lower the quality that is a scientific fact judging by how the quantization works. The big point that all seem to miss is that beyond 44.1kHz one would not be able to tell the difference and basically is pointless to have so much storage space spent for nothing.
Exactly! 22K is pipe dream for most people; most adults hear in the 10 - 16K range, dependant on age, and the music doesn't sound 'different' just because we've lost a few KHz here and there! If cymbals still zing, and ting like they should, then excessive high frequency recording is a waste.... I know in some circumstances that there are higher frequencies that work with others to give a certain order of distortion that resonate well (certain harmonics) that if missing would destroy the feel of the music and maybe even notes being played, but these are all recorded within the 'lowly' 16/44.1 redbook solution, so it's not an issue!
As you say, storage space for needlessly high 'resolution' files is just pointless!
I love good old analogue, but I also love my (well recorded/mastered) CD's... :-)
Great video. I’ve had the same concerns myself and you properly articulated why. The best ever hifi upgrade I did was buy a Nord One Up amp. This was a game changer for my PMC OB1s speakers. I have heard differences between formats but not in ABX tests. What I mean is the Linn 96/24 for example sound great but think the real reason is the the audience for these are people who care about music and the producers bother to mix the tracks well in the studio. i.e. don’t dynamically compress the music. Place instrument well etc. It’s not the format it’s the production. Madonna immaculate conception on cd sound just as “interesting” and alive as any 96/24 recording do.
Thank you. Thank you. I’ve been dealing with these toks my entire life.
I really appreciate you taking the time to explain this in a way a layman like myself can understand. I was finding myself obsessing a bit on trying to get these higher bitrates and it was frustrating. I am at peace now with how things truly work. Especially someone like me who listens to music on bluetooth!
This is a very fin topic.
Someone should have a discussion with the hi-fi (consumer) industry about this and then with the audiophile listeners using converters at 768 sample rates when listening to lower sample rate files.
Thanks so much for clearing this up. A while ago I did the 320kbps mp3 vs wav test and could not hear a difference at all... With high grade converters and headphones! I thought my ears were to blame.
You are not alone! Being human is to blame, not your ears :-)
Good on you for actually doing the blind listening test. A lot of people with surprisingly strong opinions on this never actually do that.
Listening to Spotify premium 320kbps Vs CD quality music (Tidal) is a big difference in musicality. I can EASILY hear the difference between the two. With lower end equipment though that detail that you gain may not be as obvious to your ears. Going back from Tidal CD quality and higher to Spotify premium actually sucks it's so noticeable
@@zachunter2357 Hey Zac, you must have excellent ears! Maybe it also depends on the mix. I will redo a comparison to double check :)
@@georgearrows7701 also remember that the sound coming out from your headphones/speakers is going to be affected by everything that it goes through between the source and the end point. So if your pc has a shitty DAC it will lower the quality, a worser power source will also affect it. And also, the mastering of the track will affect it too. Start a free trial on a hi-fi service and listen to some different tracks. Do a side by side comparison
@@zachunter2357 That's the thing. I am using a pretty expensive semi-pro interface (RME Babyface Pro) + pretty good headphones (Slate VSX) and don't really hear it. Anyway, I will do the comparison again because this has been bugging me for years.
Good talk. As a matter of fact, nothing touches say, a 2" Studer and a vintage Neve console. Of course also the old outboard gear. There's a reason for all the modeling algorithms of that vintage analog gear. Yes, analog has a "smearing". But, digital lacks some body that analog has.
Meant to mention. There's nothing like the saturation sound of hitting 2" tape really hard.
Some good examples of that "tape hit hard" sound: "Best Friend's Girl" by the Cars, "Bicycle Race" by Queen, Both produced by Roy Thomas Baker. He would have the engineer hit the 2" 30ips master really hard and said 'if the recording head glows red, we have a hit.'
@@RadioCamp 👍
I wish I knew half of what you talking about. Really just wanted to know if I wasting money with tidal Master plan. If hi - fi would have been adequate. Or if I'm just imaging Spotify not sounding good from my system.. Last two mins most useful for me. Listen to what works for you. Sound advice
Well illustrated, on top of all that we should consider the frecuency response of microphones (good old SM57 does not go over 15 kHz), preamps, etc. Just saying,
24/44.1 the way I roll...
Thanks Justin - Cheers,
mvh
Absolutely BRILLIANT tutorial! Thank you so much for sharing this knowledge!
Years ago, I was tracking thru 18bit motorola converters. I was dropping the teac four Trac drum tracks down to digital. I noticed it sounded much more like the tape in 24bit than sixteen bit my sampling rate was 44.1 in both cases. I learned 24bit is better for resolution. However I had to mix down to 16 bit digital in this case. My hardware could only handle 16 in the multitrack window.
I listen to MP3s on an almost 20 year old Zune with Beyerdynamic studio monitor headphones and the sound quality is flat out amazing. 44.100/16bit is more than enough to capture and reproduce sound that humans can hear and a good ripped Mp3 sounds nearly identical.
I was running this video in background, and that 15kHz startled me, I thought something was wrong with my head. Anyways, it was mathematically proven that you only need double sample rate of what your maximum recorded frequency is, and that would give you accurate reproduction. Any errors in audio are not likely and negligible. Search for Nyquist theorem. 44.1 sample rate can be used to reproduce frequencies up to 22.05kHz. Only a few people, if any at all, can perhaps hear that. Noise for dogs.
I enjoy your explanation. BRAVO
Outstanding info and delivery!
My argument for using 24 or 32 bit float is just headroom, I can record really quiet sources and then gain them up and compress the living shit out of them and the noise doesn't come into that audible range. For consumer side I go 48/24 because it is standard for video.
Higher sample rates introduce less latency when monitoring natively via the DAW. Once tracked at high sample rate for low latency, there is no need to introduce sample rate conversion, which will cause degradation.
I do a lot of sound design and multiple renders of audio. Stretching, bouncing etc and have recorded at 96k for the last 12 years for that reason. Also my clients want 48k almost 100% of the time so the conversion is seamless this way. I think some of the “myths” of higher SR are leftovers from when converters weren’t as good (maybe), like early aughts. But if you really wanna hear a marked improvement, get a master clock. That was an eye-opener. I run 96/24 with Lynx Auroras and a Big Ben-that’s enough! But this video gets into consumer habits, and listening-and I agree. CD is fine and I really prefer vinyl. But it’s apples and oranges comparing processing digital audio with delivery specs vs listening to music. My .02.
Absolutely, for sound design or sample libraries where you’ll be time stretching audio or pitch shifting down significantly, higher sample rates make sense. That’s one of the special cases mentioned near the end of the video. And if you’re working primarily with video, 48k there is the norm, so may as well deliver it that way instead of sample rate converting a 44.1 file.
Thanks for the comment,
-Justin
Ah I wrote this literally 1-2 minutes before that caveat, haha. I also agree with the many other attributes mentioned as to creating good recordings, or rather, the Things That Make SR And Bitrate Moot. Like bad preamps, oppressive, stark, reflective rooms, poor levels, and questionable choices-the list goes on!
Man, I'm 34 and I still use a tascam 4 track cassette recorder and a Alesis 3630 compressor for my music, and people that hear it don't tell me, nobody will like your music because it was recorded on a tascam cassette recorder and a Alesis 3630 compressor
Becuz: the resolution of good quality tape and agood cassette machine and analog outboard gear is better than a lot of digital stuff. Especially when you start using plugins.
Great point, also if the music is great all the techy things don't matter as much. LIke, what is the best mic? The one with a real artist in front of it. WHIle i've heard some crappy recordings done in garageband. I've heard some great stuff as well. Its more so the music, and the person turning the knobs.
Thank you Justin, this comforts me in my unashamed attitude of "If it sounds good, it's good"! I have a question about the "Air Band" on Maag plugins, I really like the "brightness-not-harshness" it allows my 58 years old ears to perceive and appreciate on instruments and mixes. I usually use 4-7dB @ 20k and only recently used 15k on the EQ2, should we be cautious of unheard frequencies causing aliasing generated by the plugin at 20 or 40k?
Good to hear! Aliasing should’t be a problem and should be filtered out if everything is working properly.
But there’s a chance that to you get ears you might be boosting more HF than you realize :-)
It could be good to double check things on a frequency analyzer to make sure the super high end you have trouble hearing doesn’t look to crazy relative to references.
Either that or visit a high school classroom, draw your nails across the chalkboard to get their attention, and then ask them for feedback on your mix ;-)
Hope that helps!
-Justin
I think there is a better low bitrate formats than the mp3 like m4a aac, ogg, because the spectral analysis sometimes shows that some mp3 converters screw up the songs by cutting too much frequencies. So you still get 320kbps but in reality it's less.
I remember converting the black album cd in the '00 to various kbps mp3, starting from 32kbps to a variable which at that time was up to 220 kbps I think. And the sound depended a lot of the speakers. In the PC starting from 128 kbps sounded good, but in the hifi equipment to a properly bass sound must had be the variable, not less.
Even if actual 320 kbps mp3 is said to be enough, I consider quality cd, be WAV, be FLAC, etc, the most honest format to sell music, just in case, the original, nothing removed.
Sounds reasonable to me! Though I understand why people don’t want 4x larger CD file sizes on their devices or streaming sites for practical reasons.
-Justin
So, Justin, I see you've changed back to another JZ Mic which looks like the V67! Nice choice!
As for the topic, I really enjoyed listening to this and your perspective. I have to admit that I was somewhat of a numbers-fan and thought that bigger meant better. However, after listening to you it made sense to me in that you really won't hear the difference on the listening end of the sound. And I'm convinced that you need some really high-quality headphones to even attempt it....if you can. I've tried and didn't hear a difference. I am going to have to do some really close comparisons when I do get a chance to see if I can capture the differences between the two resolutions. Again, thanks for this video Justin!
When he played the 15k sound at 8:23 I thought there was something wrong with my headphones
Same lol
flac is lossless. A great mathematical data compression trick. I remember it translating even highest samplerates lossless in audio information.
The rest I enjoyed a lot.
First time watching your videos. So relatable. I’ll watch all today and all my family members and neighbours will too 😂. Thanks a lot
Totally agree. In fact I could perfectly record at 16 bit and be really happy.
Love your content bro. I'm 28 years old and can hear clearly from 30hrz to 22khz. I tried many app from play store and that's my hearing rage. However that higher frequency I perceive them as noise.
@StringerNews1 scientists lie too.
Thank you. Your video helped me staying with Spotify for the UI, multi-platforms (Connect) and international songs selections. Honestly tried Apple Music and Tidal and just not getting any additional benefits.
Yeah, 320kbps is a pretty amazing consumer format. Improvements from there have routinely been shown to be existent in double blind listening tests, so whichever service you prefer for other reasons is probably the more important variable. Glad you found a choice that makes you happy!
Very best,
Justin
I use to bounce my music from Cubase (6) to a 44.1kHz/16Bit wave file, then drag it onto my iPod mini, go out to smoke a cigarette and gaze into the distance. It occured more than once to me, that I was bouncing out an 320kBps MP3 and was not aware of it. The funny thing is: That iPod makes it a blind test without my provision - it doesn't show or tell you in any way which format is being played back. BUT: My nearly 40 years old ears seem to reveal it - whenever I listen to one of my productions and I have the feeling it's not uncompressed sound... guess what: In fact it would be compressed, really. I would yet have to fail on that one to conclude an MP3 sounds just as good as a PCM. But don't get me wrong: I agree wholehartedly to what you say in this video.
Thanks for this post! I’d love to hear your perspective on apple digital masters, I feel like they sound better but I don’t know the engineering behind it.
One benefit of using 96 instead of 48 at recording is the AD converters allow me better headroom.
Not sure how to explain this in technical terms other than what I see when I clip the sound at 48 compared to 96.
Another benefit of higher sample rates is signal latency.
Although I've never considered 96 being “super high resolution.”
Headroom and dynamic range is a function of a bit depth, and of the analog components of your converter. Sample rate just doesn’t play into it, in theory or practice.
If your converter works differently at the two sample rates for some reason, that could be possible I guess. I’d like to know why. That seems like an odd design. But that seems unlikely. If anything, it could be slightly less easy to clip a lower sampling rate because you are dealing with less signal overall because the reduced supersonics and lower anti-aliasing filter.
Have you done any properly controlled tests of this where you can absolutely confirm this is the case? Please share if you can! I’d be curious to know more.
As I’m sure you sneaky know, we all think we hear things that we aren’t really hearing. It’s happened to all of us. I’m sure you’ve had the common experience of fiddling around with an EQ knob, thinking you were changing the sound subtly, until you realized it wasn’t engaged, or you weren’t on the right channel. That’s just part of being human.
As powerful as we can develop our listening skills, it is true that our minds will always be more powerful still.
If you have a test you can share that confirms this, I’d be very interested to see it. Thanks much!
Hope that helps,
Justin
@@SonicScoop Many thanks Justin!
I noticed it when running outboard reverbs both at 48 and 96.
At 96 I had more headroom before the signal clipped in the converter, RME ADI-8 DS Mk3 via ADAT to/from Apollo 8.
So it was purely by eyes I noticed about signal not clipping at a certain level.
Nothing else was engaged or changed so I was a bit surprised myself.
Probably more to it than headroom being changed then : )
I'm like you-being aware of the sound while fiddling and thinking yup that's a tad better-and realising the plugin wasn't active : )
I have that perspective when listening to anything these days but trying to explain how the brain fools us is a difficult task but I'd be happy if you talked more about that, blindtesting, do we actually hear the difference we think we hear etc etc.
Thank you very much. Now I can stop searching for "better sound" that I cannot hear and stick with my humble music streamer and Cambridge Audio.
Another well-reasoned and delightfully delivered info download! Thanks, Justin!
Try as I might I have yet to be able to hear the difference between cd quality and the high res audio, which could explain why sa-cds never took off. I’ll have to try the MP3 320k to see, but I know that at 256k I can tell but it’s really difficult.
Great info, thanks!
You're sorta right and sorta wrong. When testing my fave synth at 2441 and 2496, I was shocked at the difference in clarity. Always good to start at the highest possible quality and then Downsville, if needed ... that's my 2 1/2 cents.
I think I mention in the video that synthesis is one of the reasons you might reasonably use a higher sampling rate :-)
The other thing is that although we do have the best audio formats available to consumers now, they don't listen to music in any way to take advantage of them. Phone speakers? Laptop speakers? Alexa speakers? People aren't really even listening in stereo.
It’s true, people can listen on some pretty garbage speakers these days! But on the other hand, if they wanted to, really great sounding speakers and headphones are available at a much better fidelity and a much lower price than ever before in history. That’s kind of awesome.
Let’s not romanticize the past too much either though. Back in the day, most consumers also listened on total garbage speakers and hardware, often as bad or worse than the laptop speakers of today :-)
But people have very fond memories of listening to music on their terrible tiny old transistor radios, or even today on their phones and laptops or even a single shared earbud with friends.
As cool as good audio is and can be, music is ultimately way cooler and way more powerful.
Hope that makes sense,
Justin
@@SonicScoop Hey Justin. You're right of course. Transistor radios were shrill and distorted. I inherited a basic little reel-to-reel machine when I was about ten, which only had one speaker (even though it was a stereo tape head). But then we also had a radiogram! The turntable in it ran at 33rpm (or less), not 33/3rd. I only realised when I took my albums over to a friend's house, and at first thought their machine was running fast. But everyone else's was the same, so it was our radiogram that was wrong.
I would somewhat argue against that, I would say that a lot more people have headphones that sound good, compared to how many people had good sounding headphones or stereo systems in the past. So while some listening, does take place on sub par playback equipment, a lot of people actually also listens to equipment that is far superior to the typical listening equipment just a decade or more ago.
However, that is an issue, that mixing and mastering focuses so much on speakers rather than headphones, as most listening with quality equipment these days is actually with headphones, compared to the past when stereo speakers were the dominant listening environment of quality. This causes a lot of issues with the stereo representation, where speakers provide a channel crosstalk that doesn't exist in headphones, and the fact that we can't tell the direction of low frequency sounds in a room, but if if is only sent to one headphone we can.
This should be a mandatory lesson for anyone trying to understand digital audio. At least now I know I'm not crazy after reading the audiophile garbage everywhere. The marketing has gotten out of control & sadly pushes over taxed hardware basically to scam consumers. 32bit float @ 192Khz even for most science is insane, But if you need Auto Tune on every song "Go For it" Clearly cheaper than actual lessons on how to stay in key. In my experience going from 16bit to 24bit was a great improvement - Beyond that I can't tell the difference - at least not with a decent recording. Yet the Audiophile branding just keeps pushing the envelope "I think They-- They whom ever They are-- Have flown the koo koo's nest. The test of who's audio sweep sounds better than the next -- Great I'm 50 & still stuck hearing an 18 & 19 Khz whistle out of $10K speakers being sold as "THESE are the Golden Turd" VS my old Polk Audio's I've been mixing with for 30+ years. GTFO.... This vid IS true Factual Gold THANK YOU... Also helps be understand why the headphone market is so wacked as well.
@nicksterj Well the difference between 16bit & 24bit is a huge difference in the quality on guitar ad/da - Going from the 80's 16 digital crap compared to today is night & day. No one I know is jumping to drop their new Samplitube or Helix to grab a late 80's Zoom pedal because they can't tell the difference. There is an Absolute difference, But the jump to 32 bit isn't proving to have the same effect.
Well done on this video! I have been singing this same song for years on forums and with students. As a delivery medium, why do you need more than 100dB of dynamic range? (dithered 16 bit). The part I think many still struggle with, and I can see it in some of the comments here, is not understanding the bit depth of a session. (Speaking about Pro Tools here, but I believe other DAWs are similar). If set my session to 16 bit and fill it with 16 bit files, we are not operating in a 16 bit world. Every DAW these days has at least , a 32 bit floating mix engine. You are mixing and outputting a 32 bit signal IN SPITE OF THE FACT THAT IT MIGHT BE MADE UP OF 16 OR 24 BITS FILES. The bit depth of the session only relates to the bit depth of any files you record into the session or any files you import that require conversion.
I started as an engineer in the 80s. 60db headroom was about what we had. When the 16 bits came in no one could believe how low the noise floor was. All DAWs now have 32 bit internal buses and some even have 64 bit summing. No one seems to understand. I still deliver projects at 24 bits as otherwise, people don't think they are getting their money's worth. This is to make vinyl from lol
I have 100s of classical cds at 16 41k. The biggest difference I can hear is not in the quality of the amplifier, the DA converter, the headphones, the full tube amp, the toroidal transformer... It's in the microphones, mic placement, instruments, studio preamps and mastering.
I do think a small difference is gained however in SACD.
I use tune in and very happy with it, and it's free on my onkyo
Great discussion/explanation...... thanks for putting these concepts into their correct context.....
i don't seem to hear anything above 16khz. when i was a boy having equipment that had frequency range up to 12khz was quite good. and everything sounded just fine - percussion etc. for example a sharp boombox. or a turntable with a built in amplifier. they sounded just fine.
Thank you I just discovered your channel, this was a great video!!
another win for Justin C!!! Great resolution analysis sir!!!
Most of the difference to music quality appears to be down to the recording and mastering process, in my personal experience.
While 320 kbps MP3 might be hard to distinguish from 16/44.1 FLAC... I wonder whether that's not really dependent on the hardware to a good degree. The better setup, the easier the perception of transients and hence space, distance etc., might be. I can for sure tell that the quality difference between streamin of something lossy like through Spotify versus lossless like through Tidal, is night and day, in clear favor of the latter. That is though probably also mostly due to Tidal sourcing the tracks much better.
I've been custom-upsampling (like 64M taps sinc filter using SoX) my FLACs to 24/96 (for my phone) and 24/768 (for my home setup) because it gives me a bit more refined, clearer and smoother highs, which I actually hear the difference in (although the differences are kind of subtle, they won't really hit one in the face), and that's comparing FLACs, and even that on mid-fi equipment, nothing that breaks the bank. MP3 is really out of the picture there. Sorry for not having done the double blind test experiments! Will for sure try that though.
Also, today's delta-sigma DACs and even some other DAC tech like R2R tend to oversample themselves, unless you supply them a high-enough input stream. Save for Rob Watt's M-Scaler or something in that league, the small chips of these DACs that need to do their resampling in real time can't really compete with an offline process that takes a few minutes per track on a modern CPU core and a good 6 GB of RAM to finish...
And another very clear benefit of oversampling to mention is that today's music that gets released is most often overly loud and already digitally clipped, which means informations is already lost in there, mostly impacting the higher frequencies. A proper upsampling process (after digitally lowering the volume beforehand, sometimes by as much as a whole third), can reconstruct the waveform and partially undo the damaging effects of digital clipping. Perhaps it is this that justifies the oversampling hassle to me, since the space storage and the bandwidth between my home NAS and my living room computer doing the audio playback, is not really an issue.
Hey man SUPER VIDEO !!! I thought how strange he says a frequency and I hear it, it is early in the morning and while enjoying a cup of tea and coffee I first listen to EWF Shining Star, All About Love, Yearin Learin, at a low volume level , to also train my hearing .. and check where Mick Guzauski pops up .. but yesterday this video of you also put my checklist ... ha ha ha I thought I can hear it well played back 3x yesss I hear it everyone ;-) thanks for the unconscious test.
Here is a blind test that will change your mind, Justin. Listen to a 320k vs. a wav or flac (create both from the best same source) of The War on Drugs' "Lost in the Dream." I have, and for a fact, I can tell you there is a specific character that shows the difference. I challenge you to notice it, it can be deciphered in the first minute of the song. Another stunning mix was Morning Phase, equally decipherable. The sense of detail and SPACE that is destroyed by 320k is obvious to me, at least.
Most won't notice, so don't stress, that is true. But when you personally want the best, why not go ahead and mix for that. Try to hear it, try to make it.
Interesting to hear! What are you using to listen to the these properly double blind?
I can tell you that I have had similar experiences in sighted listening tests.
For instance, when I created a similar listening test for our readers, I could have sworn up-and-down that I could hear the difference when listening sighted, and that so many people were going to get it right.
But as soon as I properly jumbled them up so I didn’t know which was which, those differences seemed to evaporate like a mirage.
Ultimately, the results of thousands of responses to our online test were no better than chance:
www.trustmeimascientist.com/2012/04/02/take-our-audio-poll-do-we-need-higher-definition-sound/
If you can consistently distinguish this, that would be amazing! No one in the world as of yet has been able to show that they can consistently distinguish between 320kbps and any higher resolution format in a proper double blind listening test.
I’m not saying that it can’t be done. Just that it never has been yet on record. If you can do it, that would be amazing. I’d happily write a glowing full length article about you and how you are able to do this so we can share it with the world.
I’ve had this challenge out for almost a decade now, and so far no one has done it yet. It would be awesome to finally put a bow on it.
What software or hardware solution are you using to do proper double blind listening tests on your end? Is it an ABX tester? That could do the trick.
Thanks,
Justin
PS: Here’s the original challenge on my old blog. It’s been seen tens or hundreds of thousands of times, shared all around forums and all that, but no luck yet! Be our champion :-)

@@SonicScoop Well I went, prepared to be humbled, but the links for Line 'em Up and Kite of Love are broken.
I did find in another of the articles the foobar can have an ABX tester plugin, I'll do that. My previous tests had my wife switching the tracks; a program that does that will be fun, so thanks very much for that.
Also, please know I meant no disrespect, I love your channel and learn what I can from it :)
320k MP3 isnt a "hi res" format - its still a compressed (althogh half decent) file. Im pretty sure Justin is referring to higher sample rates and bit depths.
To me... Other than Sample Libraries or Bats... The Higher Sample rates are best for Audio Restoration where you are capturing Archived Media... and Forensic Audio
Exactly what i been looking for
Last week I switched to high sample rate for my mixing template. Not for that "super high quality" sound (actually when the files were recorded at 48kHz than they CAN NOT be converted to higher samples rates with all that extra information) but for the digital processing I use. Some of them have oversampling but some simply don't. And those plugs which don't have oversampling CAN achieve a more accurate harmonic saturation/distortion. It depends on how well the plug-in was coded. So the sampling rate of my project is high but my exported file is still 16Bit 44.1kHz/48kHz. The only downside is the processing power - but hey with this "trick" you convince yourself using less plug-ins 😉
If it works for you keep on doing it! I would suggest that you eventually do an experiment though, just for fun and certainty. Try this:
Bounce your mix from your 48k session. Then, copy your entire session from 48K to 44.1 K. Then, bounce that otherwise identical mix as well, to the same bit depth and sample rate.
Now, load both up into an ABX tester and see if you can hear the difference!
This would be one way to confirm that you were actually getting the benefit you hope you are getting. Maybe you are, maybe you aren’t. I don’t know!
I have recommended this to a friend who worked at 88.2, and they have found that they couldn’t tell the two files a part. In some cases they stop using 88.2, in some cases they didn’t.
But in no cases so far did they hear anything like the kind of difference that they thought they would.
Maybe your situation will be different. In either case, if you try it, please share the results here! A lot of people would be interested to hear them I think.
Thanks and I hope that helps!

I downloaded audio from a song posted to TH-cam and then listened to the CD version of it a few months later. I was shocked how some of the percussion sounded very clicky on the CD and warmer on the mp3! I’m not sure what YT does to the audio when uploaded but it definitely didn’t make it sound bad ☺️
TH-cam probably removes more high frequencies than is needed, especially with its standard resolution videos, which often have bitrates as low as 128kbps for sound. Unfortunately, they don't offer any 320kbps audio that would be indistinguishable from any higher resolution.
Their 256kbps versions, which can only be found on their HD videos, is not bad at all, but the codec is not as good as those from other audio focused sites from what I have found.
Unfortunately, I doubt that you downloaded even the 256kbps file from whatever sketchy side served up the download, so you could be missing a lot more high frequency in the YT download than is ideal.
Go check the file and let us know what bitrate you got. I'm guessing maybe 128kbps?
Hope that helps make sense of it!
-Justin
Great video and description of the whole high sample rate argument and how it reflects to the quality of the sound. It also explains why my interface sounds better at 48khz and up. There is an endless thread on GearSpace on the whole subject.
#GearSpace??? LOL.
i can notice the difference between mp3 320 and the cd track via a RME dac and monitor audio pl200 floor standing speakers ,only very slight differences ,because i listened to the Cd ,i prefer it ,otherwise if I just have the mp3 file ,i wouldn't complain .
What are you using to do double blind ABX tests?
…Are you doing double blind ABX tests?
End consumers getting the file in the same format it was recorded/mixed avoids a Sample Rate Conversion, which can mean less degradation. Higher sample rates give a more accurate trace of the analog/electrical wave form.
If you want to avoid sample rate conversion, don’t use the unnecessarily high sample rate to begin with :-)
As far higher sample rates “giving a more accurate trace of the waveform”, I’m sorry but this is incorrect.
That’s the exact misconception that we start off the video with, on purpose.
There is just no mechanism in physics by which increasing the sample rate can do anything except for increase the highest frequency you can reproduce.
It’s a bit of an all or nothing affair: Either a given frequency can be reproduced perfectly at a given sampling rate, minus some noise (which is determined by the bit depth) or it can’t be.
This can be confirmed for yourself with proper testing.
Similarly, there is no mechanism by which increasing bit depth can do anything but lower the noise floor.
If you believe that there is, that would be an amazing breakthrough discovery and science!
I mean, could you explain the mechanism by which anything else could occur?
I hope that helps,
Justin
@@SonicScoop when you have more samples per second, there is less rounding going on as the digital waveform tries to approximate the analog voltage (input).
A hypothetical infinitely sample rate would track the voltage perfectly, to the atomic level or beyond. There would be no rounding, at that point. Its calculus. Approximation of a circle using discrete values. More "steps" equals a closer approximation to the continuous curve.
Why not use less noise, noise is not typically desired. Even if not audible, it has interaction with the audio. There is no universal reason to not be technically better. If for no other reason, than archival purposes.
If you null test an mp3 @ 320kbs, and a 24/96 file, there is no residual sound?
Interesting discussion.

@ReaktorLeak im talking about the capture at the ADC stage. Voltage to binary. A "perfect" conversion would track the voltage fluctuations down to the electron. Otherwise your missing information at conversion. ie the information that would otherwise be in between samples, is not recorded, it is ignored, the waveform jumps to the next discrete value, the analog signal is continuously variable. Up to the limits imposed by the hardware.
Trace the outline of a circle with straight lines, once with 1" lines, another with 1/4" lines. The shorter more frequent lines give a "truer" representation of the circle. This is akin to sample rate. More samples, more accurately traces the voltage functions aka the analog audio waveform.
@ReaktorLeak you cannot recreate the circle however, because samples are discrete values (straight lines) in your example you would have a triangle. The samples cannot reflect the "inbetweens". The voltage change happening in between samples. "Reconstruction" of the inbetweens ends up in averaging. You don't "know" the voltage fluctuations, your guessing them based on the two points. A momentary transient occuring between two samples, would be ignored. It would go undetected, and get rounded/averaged away. The samples can't dectect things in between samples. They are akin to steps, not curves.
Calculus shows us that more discrete values (samples) more accurately trace a curve than less.
Its just like frame rate in video. 29fps is fast enough to fool the eye, until you slow it down. Higher frame rate is always truer to continuously varible.
@ReaktorLeak you can perfectly re-create the circle IF know ahead of time its a circle. If you do not know its a circle it could be any possible configuration of lines between those 3 points. A converter doesn't "know" the voltage fluctuations in between samples.
Its NOT just about what frequency you can hear up to. If you can't hear it your equipment might not be up to snuff, or youtube, or BG noise is masking the sound. This discussion totally ignores the psycho-acoustic dimension as well as harmonic granularity.
I’m sorry, but that’s just not correct. That’s the exact misconception that we start off the video with, on purpose.

Justin, loved it.
Three questions:
. A famed producer (I believe it was Aerosmith's producer said that excessively high resolution audio was allowing us to hear details in the original recording that weren't there and therefore were a bad thing. True/false?
. Jimmy Page said the Zeppelin catalog was recording at such fidelity it's future-proofed for years (or more to come). Page specifically said for future "higher audio standards," which as they're in the future don't yet exist. True/false?
. I thought the sound on VHS was/is pretty groovy. Isn't VHS tape a NON digital format? Hence, the sound is 16 bit which as you noted no one can really distinguish from 24 bit. Hence, analog can reproduce in the instance of VHS sound as close to the source as digital? Not a trick question.
P.S. I think one big misconception you blew-up in this video, is that if you record say, a giraffe making a sound at a zoo - whatever sound they make at 16 bits and you record it at 32 bits - most folks, including many professionals, believe that at 32 bits of 'resolution' you'll hear greater fidelity with 32 bits. You'll hear a better sounding giraffe, as well as the sound of garbage rustling on the ground. A better wind sound. Maybe human speech, better, from visitors to the giraffe enclosure.
Yes, I think those first two examples come from a misconception about how this stuff works.
There are a lot of people who are great musicians, producers-and in some cases, audio people-who don’t really understand the situation fully.
They usually have never done double blind trials on any of this, and often don’t exactly understand what’s going on under the hood. But that’s ok. They can be tremendously great at what they do and be mistaken about this. I was once.
Jimmy Page is an amazing guitar player. That doesn’t mean he knows how digital audio files work, or that he’s done blind listening tests at various sample rates or bit depths.
That’s not really a criticism. You don’t need to know any of that to be a great musician, or even a great producer or mixer.
If you had to pick between being amazing at guitar or production and knowing how digital audio works, the first too are way more badass :-)
VHS CAN be digital (see ADAT) but is usually analog yes. (Technically you could record digital signals on a reel to reel take machine, and some companies made such machines early in.) But yeah, generally analog in both cases without getting too nerdy about it :-)
Analog formats actually have lower dynamic range and higher noise floor than 16 bit. Good vinyl would be the equivalent of about 11 bit in that regard if I remember correctly. I’d imagine VJS would be around there or lower in effect, but I don’t know right offhand.
Generally speaking, any analog formats are going to sound less like the source than a 16/44.1 file. The only thing that comes close is an absolutely excellent tape machine running at 30ips. That might come close to sounding as close to the source as any reasonably well built 16/44.1 system, and would be orders of magnitude more expensive.
But analog can sometimes sound damn COOL, even if it doesn’t sound exactly like the source. A less than stellar tape machine running at 15ips could sound more badass than the original source. That’s subjective. But it probably won’t sound as close to it as even a basic stock AD converter built into a laptop. That’s objective.
Hope that helps,
-Justin
@@SonicScoop Thanks for such a thoughtful answer!
I find the only benefit of hi-res releases are that the albums normally receive a better mix, Metallica's Death Magnetic is a great example... the retail CD is a brick walled mess victim of the loudness war and due to the compression it's actually tiring to listen to it, the 24bit/88.2khz hi-res release just sounds better due to the mix and lack of compression, so I just converted the flac files to 16bit/44.1khz and burnt myself a CD that sounds better than the one I parted with cash for..
100% this. Of course it’s not a benefit of the hi res format, but having a better mix is a huge reason I buy hi res.
Yes, that is a valid reason to repurchase etc. It's a shame however that people are being convinced they should buy because of the numbers and not because of the fact you get a better mastering or better recording.
If you convince everyone it's the numbers that matter, they will rebut every CD ever owned by them and it also attacks the second hand market.
Imagine reprinting a book and encouraging everyone to rebuy because the new print has a HD font that will improve your immersion in the text.
Thank you, Justin , this podcast has changed my view on everything))
Done quite a few tests and there are subtle differences in the amount of air or silence you hear in great audiorecordings in CD quality compared to compressed mp3s or AUCs leading to better separation of instruments. This is more apparent the more the file is compressed where reverb or room tails disappear. Lossless compressed sounds like CD quality even through good DACS(use a RME babyface). I cant hear any difference in quality beyond CD quality. The differences people hear is most likely technically related…some ADDAs just record and play back more reliably than others. So in all I completely agree, going beyond CD sound quality is just a waste!👍
@nicksterj MP3s didnt exist when the debate about digital vs analouge sound started. First time I heard it was with the arrival of the CD format. The whole record industry went bananas trying to quickly digitize their music catalouge to cd with varied success. As you say, a well mixed album and mastered(this is something you really did to fit the dynamic limitation of an LP). Unfortunately almost all popuplar music today is compressed, autotuned, grid quantized and overmixed to death in the loudness war….
@nicksterj saw the resurgance of vinyl already in the 90s, but now its bigger than in a long tume. Same thing happenings ng with film cameras for example…..guess its just how thingswork. Off course the motivation will be something like sounds better, better colours, better control over gear. Dont know if you followed the development of syntesizers, it has just come around to be back at the 70s…..people search for differnt stuff and are nostalgic at the same time.
@nicksterj I didn’t say that the sales of LPs were high in the 90s, there were plenty of used record stores. Many artists started to release LPs again way back early 2000s and there have been a small audience buying these as collectables. And you are right, now it has exploded, its common to be 20-30 something owning a record player….most wont argue around sound quality…..they just keep it next to their vintage camera and dumbphone.🤣
@nicksterj there were quite a few stores popping up close to Carnaby street London very early, were completely surprised that people even cared at the time, it might be that memory plays me and this was early 2000s...seems sales really took off again mid-late 2000s in many countries with a peak in the 2020s in according to wiki. On the jazz scene it's pretty common that the artists bring their Vinyls these days. Not so strange when there is simply no revenue at all from streaming services....
This is super interesting Justin. It means I can start a 44khz project in my DAW instead of a 48khz one and use the CPU and RAM saved for distortion, analog emulation, etc to make it all sound more interesting. My main concern would be the Nyquist frequency: when using certain plugins that may not have a resampling option, working at 44khz would be worse than doing so at 48khz as some artifacts would be more noticeable and hard to clean up? Thanks a lot for this episode!
Oversampling is needed only to reduce the aliasing caused by plugins that can introduce harmonics, so saturators, clippers, brickwall limiters, fast compressors etc.
Working at 48KHz doesn't really get rid of aliasing at all, you always need oversampling to do that anyway: if harmonics are introduced to a 15KHz sine wave, in instance, the harmonics produced will be 30KHz, 45KHz, 60KHz, 75KHz, 90KHz, 105KHz etc and that's just up to the 7th harmonic and 192KHz would not be enough anymore so you need to have a sample rate that allows those harmonics to be correctly described.
Whatever harmonics go beyond the Nyquist frequency are mirrored back below the Nyquist frequency.
In instance, if you're working at 48KHz and you use a non oversampling saturator on a 15KHz sine wave, the 2nd harmonic will be 30KHz, and it will be mirrored back and appear at 18KHz (30KHz - 24KHz = 6KHz, and then 24KHz - 6 KHz = 18KHz).
@@kelainefes thanks for the math and clearing up the concept, very well explained.
I agree with all except between 320 MP3 and 16b 44,1 wav. I hear a difference.
That would be amazing! No one on the planet to date has yet been able to show that they can consistently distinguish between 320kbps any higher resolution format in a proper double blind listening test.

@@SonicScoop when I DJing electronic music on radio, quite loud, I felt that wav was more punchy. I remember John Digweed said it too but he's one of the most respected DJ on earth (the first guy who released a DJ mix in cd with Sasha) he play on the biggest systems. When it's techno and playing loud, it seems to me to be punchier, clearer, cleaner . But maybe you are right I'm the wnner asshole's cup. It was when I was 25, maybe today I would not see the difference. Thanks for this video.
This theory is true with speakers mind.
I tweeter able to go to 30k or 40k plays the 20k better because 20k is now not right at the physical throttle of 20k because it will begin to drop off at the point before stopping.
Although that theory only counts if that is the purpose of the tweeter hitting above 20k.
Physically it does give it space.
It's why 3 ways and above do a better job...
But that is there being more speakers handling less spectrums at the sametime.
This a phycical thing so the diffrence does lay in this... the audio is best to not go above 20k even though they can handle more.
There can be a diffrence in headroom with audio coming back in from highend analog equipment but not going out into it.
With that said the diffrence is so little that the complication of downsampling that afterwards is kind of pointless.
Consumer products are focused on going out which is pointless sending out anything over 20k.
There is a diffrence with some plugins mixing down to two channels but then again the diffrence here is the sound you are looking for.
There's a gain in the sound of analog emulation plugins (some of them, not all of them), but going out to analog in a high bit rate doesn't make sense.
So I would bounce each track that is better in a higher bit rate then turn down the bit rate to 48 to go back out to analog.
That is a bit of a headace though for such a tiny diffrence but that would be good for anyone with no real analog equipment.
But when it comes to the resolution at the end... then 44.1 and 48 is more than enough.
I stick with 48 due to the flexibility with video
This was a video with bits I hadn't thought about before that really relly helped me re remeber things and add a little extra in those thoughts
So, 24/48 as a standard. 32/96 for post-production RX, if necessary (the elimination of digital distortion). Eh???? I suppose the only thing that comes to mind is the air at the top for 3D resonance (psycho-acoustics?). Having a 32/96 interface, causes me to ask, why not? I get the file size argument, but being that the end product is going to be crushed by the streaming services, why not produce at the higher rates as an offset to the crushing that is going to occur on Spotify, etc. I am fine with 24/48. Really, the only real argument remains the file size within the production computer. Thanks for the emotional battle I now have to have with myself. Yeah. And you did just blow that lunch date with Neil Young. Thanks for always giving me so much to think about!!!
An excellent explanation. Like you and sub you. Can you tell me what is tape cassette Hzs. I always likes stereo quality. CDs quality is enough.
Great video!
Excellent
Great, informative video !
I'm going to simply trust my ears, I can hear the massive differences between speakers, and headphones of course, and yes my two external DACs do sound different to me (not one better than the other, but different). But can I hear the difference between high resolution audio and standard resolution music? No, I can't! So basically I don't care, standard works amazingly well for me.
I heard the 14KkhHz but not the 15.... I'm in my late 40s.
We all can perceive above 20khz
There’s a new reasearch that shows activity in the brain. The activity is where the brain perceives localization
The test was conducted with 20khz to 100khz and also most of the 66 participants preferred the music with ultrasonic content
Are you talking about a study from Japan in the 1990s, in which there was a potential preference for one piece of music (gamelan chimes) based on subjective readings of brain scans, but for none of the other pieces of music in the test?
That same single study from the 1990s with flawed methodology, dubious conclusions, which found no difference for all other musical selections, and which has never been replicated?
If it’s something other than that, please let me know! 🙃
Genuine question. I heard somewhere that 96k is a requirement for film sound/music.
1. Is that true?
2. What benefits (for film) does it give to have audio in such high resolution?
48K tends to be the standard in video production that is used most commonly in my experience. This is mostly because the math works a little bit better between 48K samples and 24 frames per second. That way, you always have an even number of samples for each frame. That’s pretty much why that standard was adopted. Hope that makes sense!
I use Wave 48K at 32 float because I believe if I yell too close to the mic, and it goes way into the red by accident, it won't distort. When I export to MP3, it still sounds good. Am I wrong?
Cool and valid content as always. Thanks
I've been saying for quite a long time, anything beyond 24-bit 48kHz (chose this really only because it's what you'd see on DVD's and Blu-Rays) is useless outside of production environments.
Hi
Great video? Does 360 degree reality audio really a good experience for audiophiles?
Really, I mean REALLY great episode!
this is AWESOME! next time I'd love to hear some peak compression on your voice to make things just a bit more audible :)
also, my cat looked at me funny when I unmuted the video at around 8:45 😹
Usually there is a whole chain of compression, limiting and EQ on the voice, but there was a glitch with Premiere' s export where none of it actually got printed.
By the time it was uploaded, getting thousands of views and discovered, it was too late to change it 🤷 TH-cam doesn't allow you tor replace audio or video unfortunately.
Ironically, the only complaints about this video's audio quality is that we didn't degrade it ENOUGH by making the audio less pure with tons of compression, EQ and limiting.
Kind of shows what really matters in audio. In a literal sense, this uncompressed and untreated audio is more "real" and "high fidelity" than a voice that has gone through normal amounts of audio treatment for this kind of format.
