I use phase cancellation all the time (in Ableton). If I'm processing a sound and making a very wet or distorted sound, I reverse the polarity and mix it back alongside the original channel, and because effectively all of the tones that haven't been changed are cancelled, all that's left is the new processed sounds - its basically like always having a dry/wet mix. Fun shit.
I don't want to sound picky but triangle waveforms don't have all harmonics but only odd number harmonics, the fundamental being number one and so on... Anyway a great application for phase cancellation you haven't mention is the making of accapellas. If you have an instrumental and the orginal track, put them mono and reverse phase of one of the 2 and you get the accapella.
Phase cancellation is fun. I've used with two audio files, one instrumental and another one with singing, to subtract things from it by inverting the other one.
Technically, you're right about phase being essentially the start of the wave. In a more specific sense though, phase refers to the offset of the wave relative to the origin. Another way to think of it and much more relative to sound design is that it's the fraction of the wave that has passed relative to the start of the wave and the wave's cycle (aka period, period being the time it takes the wave to return to its starting position).
Yea balanced cables are one of those brilliant yet simple ideas. Basically the source sends the sound out twice, once with the phase flipped. At the destination, the flipped signal is flipped again and the two are combined (internally they're subtracted, but same thing). Because you flipped the phase of the signal twice (at source and at destination), it doubles. Because you flipped the phase of the noise once (no noise at source), the noise cancels. The technical term is "differential signaling," it's used all over the place in electronics and computers.
Congrats on your new production series, dude. This is super duper exciting. Your tutorials are the ball. I guess that most of the things you'll cover here already are on your tracks from scratch so it's a great way to attract new viewers that don't have as much time as I do to watch an entire 1 hour video.
SeamlessR The trumpet is a great example of harmonics! Without pushing any keys you can play a low C, low G, C, E, G, Bb, high C, high D, high E, etc. just depending on how fast your lips vibrate. The keys just pitch all of those notes down by semitones.
Hey Seamless, it's actually XLR that uses Balanced audio to cancel noise with Phase Cancellation, XLR has 3 connections, Hot, cold, and earth, and the Hot and cold cancel each other out, where as on a TRS the 3 connections are Left audio , right audio , and earth. This is why DI Boxes often turn TS or TRS cables into XLR cables, because it's getting Unbalanced audio signals from instruments or microphones (standard audio signal) into a balanced XLR signal (a signal that uses phase cancellation to eliminate noise) Also this is also why XLR Is almost always mono and TRS (not TS) is stereo compatible Hope this helps :)
Awesome video, as always. Just a little detail about a thing you said. I wouldn't normally comment about something like this but you asked me to in the end of the video xD. You said that a balanced cable is not a stereo cable. That depends on how you use it, what comes before and after the cable. You can use a balanced cable as a balanced mono cable, but also as a stereo one. Headphones have a TRS 1/8 inch connector right. And some mixing consoles have a single 1/4 inch jack for effect returns so you can use just one balanced cable from the outboard gear to the console, using it as a stereo cable.
Cheers this is the most cohesive explanation of phase cancellation and interference I've ever heard BTW doesn't a filter work by phase shifting the frequencies, causing cancellation at certain frequencies?
So is distortion then also a result of phase cancellation because it is adding harmonics to the sound? Also, could you do a tutorial on the haas effect, how to use it to pan and how to avoid phasing occuring when making a sound mono after using it? A tutorial about mono compatibility would also be nice.
Very good video. I took electrical engineering classes in college where we studied wage forms and how their phases which actually impacts performance of electronics. Having waveforms cancel each other out isn’t a good thing in EE because the resultant signal is linear and not useful. One comment, you aren’t hearing the “difference” of the signal but actually the “addition” of the signals. Though if you change the phase 180 degrees and then subtracted it I suppose you would be right :)
Okay i'm just learning about this over the past couple if days, couldn't figure out why my final spread was sounding so fucked up, but I'm curious, Are phase cancellation and phase alignment the same thing ?
+RellyAlexander That's hard to answer because phase is over time and cancellation is technically only reversed polarity. You may be talking about time align. phasing is a shift in the wave form over time. Time align is more a shift in the beginning of the wave to start at the same time as something. Drop a stone at opposite ends of a pond and the waves over lap each other that is cancellation. Drop 2 stones in different areas at the same end that is phase alignment ish the waves still clash not as much that is phasing. Drop 2 different sized stones in the same spot at the same time you get one even wave completely different from them individually without clashing. Time alignment. In other words there may be more than one issue going on for you to look at.
***** If this went straight over your head, I think you should get more familiar with your software first. Start with videos/articles about Synthesizers, Bass and Drums, and just play with your software for a couple weeks.
I have a question about ASIO4ALL... when I select it in FL Studio it makes my sound not work for everything except FL..... lol am I doing something wrong? I do have the audio setting (realtek) the same in system and in FL (under ASIO4ALL).
Asio driver does this for everyone. Not sure why but if you want to hear (or speak) something outside FL you need to use your primary sound driver. But i wouldn'trecommend it because primary sound driver is pretty bad usually.
GeekyGamerChik In order to reduce FL Studio's latency (i.e. playing notes within a few milliseconds of when you push buttons), it needs to make sure that nothing else can "distract" your hardware from playing sound through FL Studio. If it didn't, you would hear occasional glitches from the hardware trying to process more than it can handle. Usually, there's a delay between hardware and software, to allow for processing time of multiple applications, but ASIO tries to minimize that by reducing the number of applications that can request access through the hardware.
Hi seamless, thanks so much for this video - it was really helpful! Just wanna ask: how do you prevent phase cancellation in mono? Like, sometimes if you're applying a stereo effect, it sounds good in stereo, but when you put it in mono it kinda screws up.
Oh, so now I wanted to do a Boards of Canada style randomly detuned sound with 3 sines and everyone being permanently and randomly detuned and ended in heavy phase cancellation "pumping". Sigh. Seems like there is nothing I can do because the harmonic concept does not like full randomness.
min 3 real right, funny when you do music on headphones and dont hear it on the speakers. nice tutorials, if you have some music left i always need for animation background sounds, get your name named for sure, just to buisy to do all ;P
In physics we'd call it interference, but I guess in sound design you don't want to use that word because it'll make people think of weird stuff going on in your cables ;)
I thought "harmonics" were overtones. The math I learned was this,, The harmonic range goes like this EG, A, 440 khz the harmonics that come off this note, are 550,660,770,880,990 etc, so multiplying by 1 1/2 . That does not suggest that the higher the base note the higher the frequency of harmonics because the formula does not change the higher the base note.
No the harmonics are integer multiples so from 440 Hz then 880, 1320, 1760 Hz etc. But yes harmonics and overtones are different words for the same thing.
"And it's possible that some of the stuff I said was total bullshit." *mind=blown*
XD after 14 min "I probably just said a lot of bullshit" like bruh I was taking notes, Now I'm about to fail my exam.

Did I say triangles had all the harmonics? If I did I misspoke and meant to say Saw waves.
oh right! my bad!
Can you further explain how to do this? I tried and it did not work
SeamlessR I think people (not you in this case) get mixed up between Triangle and Saw waves. I know I used to.

Wow we can use this to create future bass chords?

ShopSongs You're a fucking moron. Both XLR and TRS can carry balanced signals since they are both two-channel cables.
mandokir I didn't say XLR couldn't carry balanced signals, I was just saying that it's XLR cables can use balanced signals to cancel out noise :P
ShopSongs You were talking out your ass and still are.

what synth should i get if i want to make music like madeon i only use sylenth now
This is great! Thanks for clearing that up! :)

Hey SeamlessR! Have you ever considered doing one to one tutorials through remote access?
Quick question: If I'm brand new to music production should I be starting here? I had very little idea about what you were saying.

hey! could you make Baby bash - Fantasy girls Bassline?
thank you so much
Thanks
what happens if i pan a signal to R and the same inverted signal to L?Do i hear cancellation?
This was extremely helpful :D
Thanks for everything!
Thank you so much brother!
Man you're the best !! thank you keep doing what your doing !
A detailed video about phase cancelation. Plz
so,
that's where that noise I hear when playing sine waves on the keyboard is from
that's Mind Blowing

hey! Very impressive channel! :) this little video also made me realise things and fill the gaps .. thanks! :)
hey SeamlessR do you have these videos on DVD or for download?
SeamlessR is this how noise isolation headphones work e.g: when it plays the reverse of the noise outside so that you as a listener do not hear it?
***** haha i get mixed up with them both XD thanks
Correct me if I'm wrong but doesn't you use the phase cancellation when bringing out vocals using the original track and the instrumental? :)
For the love of god, please make Production Basics a reoccurring thing.
lmao that makes fm make a lot more sense! I thought there was some mystical and unseeable lfo making the waveform change pitch like that xD
Seamless, what kind of production studio headphones do you use?
so why doesn't phase cancellation happen in other synth generators like 3xosc.
It does... why do you think that?
i thought all of this would fly over my head but the first few minutes intrigued me.
now i know what the hell sine waves and saw waves are lol
