Nice work, Alex. Lots of great info here, especially the warning to leave some of the ambiance when doing noise reduction. I used to think it was cool to kill everything but the dialogue. Then I realized that the real world doesn't sound like a studio 99.9% of the time.
Let me just mention that both of you guys are my Sound Gurus! I have learnt so much from you @Curtis Judd and now @Alex knickerbocker is just taking me to the next level ! 🤍
Would you consider doing a tutorial with several examples of field audio with different background noise/problems and showing us how you would "fix" them? I'd love to see how you would use these tools that you've showed us on more amateur-recorded audio.
I was worried when you started talking about cables...then totally won me over with Canare. YES. Quality cables without all the snake oil. Wonderful.
Haha, no snake oil here! Trying to get real info and quality recommendations out there, no brand marketing nonsense.
@@axk Good on you. I've been a guitar player for ~15 years, but I'm also an electrical engineer, and the number of times that I've seen snake oil either peddled to people or being praised is a sadly large number. Having debates with people about Cable A and Cable B being electrically and physically the same, but people still swear by cable A because it's the "cool" cable brand.
That's what lead me to find Canare, it's got all the robust quality (I have cabled I've toured with and used on all sorts recording projects for years still going strong!) and very little of the marketing crap. Just good ol' quality stuff. :)
Loving the videos, too, thanks for taking the time to make them. I love audio stuff, but I find that audio for cinema and video projects is very different in some nuanced ways from audio for recording bands or live sound. Thanks for helping me learn!
i like your fix it on set, versus fix it in post approach...however, my last shoot was done outdoors where there was heavy traffic on the street and since it was near LAX, a crap tone of loud airplanes flying overhead ever couple of minutes. it was a nightmare and heavily relied on heavy noise reduction in post.
Thank you for your video!! Izotope RX Elements is on sale right now its around 20$ definitly worth it. I bought it primarly for automatic phase rotation. To adjust phases and gain a little more room for the peaks in order to less compress the audio. But noise reduction is also very cool.
Next time you say something like the order you should do some actions, I would recommend adding a text layer with that list, because this way is easyer to learn the steps.
Anyway I love what you do.
Keep it up!
Can do! Thanks for the feedback, definitely trying to make this stuff easier to understand.
7:31 regarding the noise control: I tried the noise control in Rx Elements, Final Cut X trial and Davinci Resolve free and, I would say that I am nit an expert, but personally the noise canceling from final cut and Resolve sounded subjective much better than the one of rx elements. An strangely RX Elements didn’t recognized any noise while the both videoediting programms did. Also the both video editing programms I mentioned above filtered noise quite well and like you say, I didt the same newbie mistake and added too much of noise canceling and effects, which results in artefacts or robotic voices.
There is a great tutorial from Davinci Redolve for Fairlight. It’s direct from BlackMagic and you learn so much as a Newbie, thats great.
Now I think a healthy workflow is much more importthan, this plugins. You need to really understand the matter and also learn badcis of physics of sounds. Just doing magic-pill plugins or tutorials won’t really make your Audio really better. It even can trash it more if you use plugins in the wrong way.
I would everyone recommend to take yourself time to learning this subject and do Audioediting and Mastering with lot of time, patience, care and open-mindedness to learn.
I got rx elements free with my tascam dr-10l. Definitely a great tool
Really appreciate this video. Thanks for your overview of the elements package!
This was incredibly helpful, thank you! Subscribed, thumbs up, and notifications on. Awesome info man.
Why don't you give the information on the Cubase software: Wavelab? can you please p[provide these methods on Wavelab?
What is the diffence between the standard RX and the Advanced RX?
Hi Alex! Thank you for a great video! I was wondering, what do you think about Wavelab’s Restore Rig in terms of noise reduction and other repairing tools. Do you consider it a good plug-in? What do you like about it and what you don’t?
I have a lip ring that sometimes clicks against my tooth when talking. It doesn't happen a lot but maybe the declicker might help?
What do you suggest for De-Hum?
Does it work on Final Cut Pro X?
Please add some examples. I think the value is seeing the actual before and after.
The best noise reduction is a good microfone ;)
@Andrew Richards My spell checker flagged "orlmost". What are you using?
Like, thx
I hope i can give you 2 million subscirbers so this get noticed
You look like Jose Gonzalez. lol
I’ve been using your EQing techniques and it’s really helped the sound of my videos. And here’s another great video! Not too long ago I made the rookie mistake of over doing some noise correction to try and remove a hum, but only ended up exchanging the hum for a muffled/slightly modulated voice. Not good.
I love you in S.O.A.D. jajajaja can you do this tutorials with Adobe Audition?
Just got RX elements for $29 on sale!! I’m using a zoom h5n .... is there a better recorder around the same price bracket?
Podcastage *and* Curtis Judd are here?
Waiting on Julian Krause, Audio University, Audio Haze, In the Mix, Dark Corner Studios, Listen Labs and The House of Kush.
Who did I miss, audiophiles?
So basically declicking will leave the ASMR and Mukbang community powerless.
The plug in can be inverted by checking the output noise only box creating a track they would blow their minds.
David Hasbrouck oh Lord Jesus no 🤣😂
Very good points....but, one word. IZOTOPE. (Hogwart's for Audio...)
What a coincidence, in late 2019 a Zoom H4 and a broken lavallier ruined about 40 episodes of a podcast. Last year I decided to buy RX9. With a mixture of RX and Auphonic, I'be been able to completely restore the files to an enjoyable level.
The Rx-Elements is just on sale for BlackFriday. Maybe it’s just an marketing trick but I bought it these days. It was reduced 29$ and all Elements in an production suite were for 49$. They also had a bigger production sweet in sale for something around 400$. This is with the standard Rx ad other production software by iZotope.
Like it sounds izotope has serval sales a year, this time in april when this video were released and now in november in face of this buy nothing day. Actually I love the idea of the buy nothing day, but if you a creative and all your equipment costs so much, it’s very seductive if the stuff is on sale. Even if consumerism is a trap. You buy stuff you not need to impress people you don’t know.
As a forensic audio professional, I think your explanation and presentation was very good! Doing several sweeps with low settings always beats one massive noise reduction pass.
Great video Alex. Any thoughts on this article though? people.xiph.org/~xiphmont/demo/neil-young.html It argues that, unless you're planning on slowing down the audio, it can actually be harmful to record at more than 48khz.
hello! my problem in recording is my background noise are crickets and that's pretty impossible to practically prevent them (and I cant hire an exterminator because I know they'll come back in the future and I'm a broke student), will you help me remove the cricket sounds?
Haha, well, an EQ can do more exterminating than you’d think. Usually crickets (if it’s only a few and not thousands) emit chirps at consistent frequencies. If you use the sweeping technique in my EQ tutorial, you can find those frequencies and notch them out pretty well.
If you need to be heavier hades than that, Izotope RX’s Voice Denoise or Spectral Denoise would be the way I’d go. It all depends on how intense or sparse those crickets are.
I’m reminded of the dialog in the film Man of Steel. If you’d heard how bad the cicadas were before those recordings got cleaned up…
@@axk this gives me a bit of hope! I actually have a sample recording of the crickets while I was singing one line. I'm using it as a practice or demo but I havent found the right way to actually remove it (which I used spectral and voice denoise), so I'll come back to your videos :))
5:00 -- Also, it's due to people who don't drink enough water every day, so they are dehydrated; and when they speak, their mouth makes this kind of extremely annoying weird mouth noises.
dude good video thanks. But what other tools? You're all like I use other tools for that........ yeah it's a super secret mystery. lol
hey alex, dialogue sounds gated to me in nearly all hollywood movies. is the dialogue really gated in cinema movies in addition to gentle noise reduction?
Totally depends on the dialog mixer’s technique. Some mixers employ expanders, some ride faders differently, some use noise reduction more aggressively than others, it really comes down to the tastes/techniques that each mixer prefers.
Also sometimes depends on the listening environment! Theatrical spaces have different requirements than headphones, for example, and that can lead to things being problematic in headphones that would never reveal themselves on big theater systems.
@@axk thanks for your quick answer, alex! i just noticed it recently with most hollywood movies i saw. i have to mix my first feature the next weeks so i wanted some reference. really could need some of your experience on this one! wish you great success bro! keep up with the high quality content.
Which Izotope tool can fix UPSPEAK?
Can you use this to remove lav mic rustle that occurs during vocals in a film scene?
but aware to not use declick on xhosa and other click languages 😂 Actually I loved this click at 5:13 better without declick than with. But I understand that in a dialogue when it pops out it can be distracting and annoying.
@Alex Have a look at the excellent Spectralayers Pro from Steinberg.
You're great at this Alex, really enjoy the no nonsense approach. The "vlog style" video isn't useful for me when I'm searching for information on how to improve. You, Curtis Judd, Bandrew and a few others always keep on topic and relay information so well. My go-to sources for audio for sure. Love it!
Bought elements months ago on the cheap from a B&H deal offer. Thanks for getting me to actually install it. Hard to walk away from Audition due to its Premiere linking. Time to put on my big boy pants.
Hi great video , I was just about to buy a Zoom H4n Pro ...why did you refer to them in that way? Have they high noise/floor level or something else i've missed? :)
Great starting comment ..get the perfect recording first.
Noise reduction dangerous.
Can confirm
Advanced cost 1000 and more dollar. :-/
Can you state some budget options beside rx elements?
What's a good way to do noise reduction live?
Alex, your videos are amazing and have been a *huge* help for me. I'm just starting a small video production business and, while I'm comfortable with the visual side of things, I realize how important audio is and that I'm severely lacking in experience there. Your videos have already helped me to salvage audio from a shoot I did inside a very loud indoor stadium with absolutely awful acoustics that I was worried would be completely unusable.
Keep up the great work!
I'm really interested in your stories with the Zoom H5, H6, what happened there? They seem to be pretty popular recorders. I think a general "2020 review" video of the H5 and H6 would get popular (especially if you explain why you wouldn't use one).
Yeah me too, I'm considering buy the Zoom H5
Wow. I just hit subscribe because of potoatojet... This is the first of your videos I’ve actually watched, and I’ve hit the bell button.
Shit, I just bought an H5
Ha, you can get good sound out of the H5. It’s just not great for recording quiet stuff where you need to turn up the gain a lot. But for just general use, you’ll be fine!
@@axk My man! I'll work with what i've got for now, i'm learning it all anyway. Any chance you have some wisdom to drop on us about audio interfaces? Last I remember you were using the Mbox, but firewire isn't so common anymore. Love the channel!
Great video! It inspires me to get back into editing. Thank you!
Have a iPhone and a Zoom H5n And been trying to record sounds around the apartment
My question is is it true or not before and after recording your subject should I record just silence .and if so why is this ?
Great information, thanks!
I am converting Vinyl records to digital format. The main issues are static and clicks. Do you have a video on how to convert Vinyl to digital, and remove static and clicks? The record player was upgraded which made a huge difference, but we still have the aforementioned issues.
That’s actually one of things that the people at Izotope got started with! RX Elements would be a great application to use and it’s not too expensive.
What is the eq you use called again ?
you r on point ...
Great video man. Keep up the great work.
Nice to see you here, love your videos too!
Love you both 😍
You're soooo supportive to other audio content creators. And that, my friend, is noble as hell!
Hey Alex! loving your videos. Super helpful. I was curious if you would do a video on how to set up audio for one or two person interview. I run into a lot of challenges when out in the field doing interviews or walk and talks. I typically run sennheiser or lectrosonic for transmitters and receivers.
Alex, love your videos as they are incredibly helpful and I am already applying your tips. But, the extreme darkness on the left side of your face is pretty distracting. I like it dark, just not that dark
Hello! I love your advices, but most of us can only afford to work in an audition, is there something equivalent in an adobe audition?
There's a sale now!
Interesting video, thanks. I can't remember if it was your previous video or an Audacity wiki where I found out the spectrogram is a great way to see clicks, mouth noises, and things like computer chair creakiness. That was a huge help when I go through audio by hand (like you were saying you do to target clicks), though I'm not sure how to effectively clean everything up. I'd assume the tool you mentioned does a better job with less effort than Audacity. Clicks that happen in the middle of the word seem really difficult to improve on. Another problem right now I think is that I'm too careful about preamp/levels while recording so I have the camera or zoom H1+ext mic down too far, which might not give as much headroom when editing as I could be getting. I think I have a theory gap I need to work on, so I can effectively use each tool and know how exactly to adjust parameters instead of just messing with them until it sounds a bit better.
I remember I used DeClip to completely restore Red Hot Chili Peppers' "Californication" album to proper listenable state with no clipping and burned it to a CD-R to listen to instead of the original master.
Thanks!!! Finally you have done it. noise reduction is always a problem... the name of the effect sounds good but I agree record well is the best solution. MB
Does this work in resolve? it isn't listed on isotopes site specifically?
Izotope has VST and AU versions of its plugins that work just fine in DaVinci!
Liked and commented on the first one, happily will like and comment again 👏Keep up the great work. I really do appreciate videos like these
Alex, have you made, or are you intending to make a video tutorial on ROOM TONE for dialogue scenes (not interviews)? Would love some advice on the proper levels to set room tone at when editing. I feel like I am always struggling between a dead sounding video with no room tone or a noise floor that is too high in the attempt of trying to create atmosphere. If you already made a video that discusses this then just point me to it. Thanks brother! Really appreciate your vids.
RX elements has been a revelation in editing and processing my ambient/dawn chorus type recording. Being able to 'see' particular birds/animals/machinery/wind noise etc is just awesome. I find the 'de hum' can be used as a high pass filter quite effectively. The only thing I"d like to be able to do that Izotope doesn't appear to do is crossfades. Also, I love the ability to listen to before/after/original etc as I go to make sure I'm not taking away from the fidelity of the recording.
Great Tutorial by the way! I love experienced people like you who share their professional knowledge! Thankd to Potato 🥔 Jet ✈️ for introducing you!!!
10:32 Order to use plugins: De-Clip, De-Hum, De-Click, and then De-Noise.
That makes each plugins the least amount of wirk and remains the integrity of your recordings.
Just explored your channel coming from Potato Jet his channel. I love your passion and deep knowledge that you show about editing audio in your channel. First thing is that some videos are very interesting like this one, but the tools aren't free so I can start experimenting with the basics. If you could provide a free toolset to start with the basics that would be great! Another remark is that sometimes you repeat a lot of the same (the lavalier tape in the clothes) which makes me skip ahead. And then I'm wondering what your goal is with the videos, you go in-depth about the topics but not enough for me to easily repeat your steps. And then if I need to Google anyway to reproduce your steps, I'm will get a lot of double content since all that will be repeated in step-by-step tutorials. Just wanted to leave this feedback instead of saying nothing and not coming back! I really appreciate all the great content!
10:20 de-clip -> de-hum -> de-click -> de-noise
Another option for cables is DIY. It's not too hard (for full size 3pin XLR anyway). You can build a nice cable from Canare cable and Neutrik connectors for a fraction of the price of a pre-built cable from a quality cable company. BUT, there's the time cost, the cost of a soldering iron (I've found it worth investing in a good $100ish iron) and solder. And you make sure you don't make cold solder joints, but that's not too hard. If you just need a couple cables, spend the money and buy them. If you need a lot of cables (rigging up a lot of rack gear, large productions, long cables) it can be worth the investment. Also, if you do have a termination go bad, at worst you lop off the connector, and spend around $5-10 for a new one, and re-terminate it, instead of buying a new cable.
Hey Alex, love the video. Question for you. How do you reduce or get rid of computer fan noises in your audio without losing much quality? I'm using a blue yeti mic with a pop filter and I'm using Audacity to edit.
Alex, I absolutely love your videos, and I use the parametric EQ trick for reducing bad resonances all of the time. I do have a question for you, would it be at all possible to request that you cover how to use audio gates? I am recording a podcast and I have a tendency to breathe in loudly/frequently and I am trying to remove my horrid gasping for air. Keep up the amazing work, it is a joy learning from your experience!
Great video ! Beaucoup de bonnes informations. Merci.
Thanks, Alex. Now if I ever recorded my voice in my videos, I'll follow at least some of these guidelines, since I prefer freeware.
Teacher, can you ask for Chinese subtitles in each of your videos? Because I like and need every knowledge you share very much! Thank you, teacher!
Love the channel Alex. Great content and great explanations! Thanks! Question: Will recording a podcast on a Mac with Reaper through a Tascam USB interface produce good audio? Or is it better to use a standalone digital recorder? Thanks again.
9:49 Can you explain the spectrum analysis with more time and breath? I really would love to understand it more!
Thank you for this tutorial. How can I fix a hoarse voice, i mean, to clear a segment of hoarse voice. What module can i use for that. Thank you
Alex, I have really enjoyed learning from you! Audio is something I really like, but know the least about. I am very new to film making, but I see that for this “controversial” video you used very harsh lighting. Nice touch. Was that intentional? Great video.
Thnx for your video Alex. Can you tell us something about de-reverb/echo cancelation?
Teacher, can you ask for Chinese subtitles in each of your videos?
Would you use these after Eq, compressor and a de esser? Or before them.
Appreciate your concise professional content!
would love to see what you think of the tools for sound that are available in Fairlight (Davinci Resolve) and how you would use them
I have about 14 different recordings of a woman having sequel encounters with a couple of guys at work however this female worked in a loud kitchen area of a restaurant and I've been using rx7 advanced to do my best to bring out the whispering & sexual sounds being made which I captured from the cell phone that was in her back pocket.
Rx7 advanced is helping me but it's been a long time since I've mixed & mastered music or cleaned up audio so its been a little rough.
I'd love to send these clips to someone who could possibly help me clean them up.
I can clean a few of them that didn't have a lot of background noise by trying to listen to just the audio being captured closest to the phones microphone by doing my best to get rid of the noise being captured in the background in a distance.
So far I've cleaned a couple that I can hear exactly what I'm needing to hear however I have several more id like to hand out to see if anyone else would like to give it a shot of cleaning up these audio clips to reveal the sexual noises wispering/talking and so on being made by the woman & man & some of the people in the background who knew this was going on as their conversations have also revealed alot of what's going on in the office or walk in as well.
what's your problem?
its her karma and it will hit her someday
why are u interfering
let it be
RX Advanced its such a powerful tool
Great job, thank you! As a solo filmmaker, this is exactly the right thing I was looking for. In last couple of videos you've covered pretty much everything. There's just one more thing I keep having to deal with when working with interview audio - room echo. I usually don't have much choice when selecting interview location and a little time to set up. Are there any simple practical things to pay attention to when recordin in a room with lots of echo? Like mic placement or anything else? And how would you deal with post-production of such voice recording? Again, thanks for your work, it' awesome!
Yeah room echo or reverb. I'm still looking for the right tutorial to help me with that.
Really great way to present things and the Q&A session at the end is a blast!
This man is a gem. Thank you
DeHum I've found to really affect the content of audio, making it sound really garbled. I'd rather use standard denoise to eliminate humming along with broadband noise
thanks for answering my questions on the last vid!
let us know why did the zoom recorders ruined your audio! what other handy recorders would you recommend?!
