The Math Behind Music and Sound Synthesis

We hear sound because our ears can detect vibrations in the air, which come from sources like everyday objects, speakers and other people talking. Why do certain musical intervals sound the way they do? How are electronic music instruments made? This video will be all about sound frequencies, wave shapes and the math behind it all.

@11:30 I want a 1 hour version of this Nice vid, new sub here 👏👏

[@Testgeraeusch]

I started making electronic music around 2011 when my friend showed me a java programm that would make the speaker play a series or beeps. I started off writing music exclusively as rows and rows of ascii code that would then be read by some newer version of the software provided by that friend and generate a .wav file from that. The catch was: every instrument had to be defined as a math function of time. Coming from that perspective, i can tell you: Sound design is a lot harder than just adding some waves. I tried, and i failed a lot. I was so happy the first time i managed to make a decent FM bass that the sound cougth me completely off guard. XD Even worse, i was never really into games or chiptune stuff; i was just to lazy to install FL studio or something similar that would make me some "professional" tunes. I eventually switched to linux multi media studio around 2015, but came back to that raw saw&square sound last year. Now i'm trying to make the most out of it and see if this weird software where every sound is pure math-hell could be used for educational purposes. The new version featues a simple syntax for microtones and even has some basic filters. And we simplified the syntax a lot. I'm currently preparing a bunch of slides for a small presentation or vid about the math of the so called microtonal intervals and natural/non-12TET tuning systems. But my channel isn't exactly an educational channel, so it may as well be a waste of time or just something for myself to spend the time in lockdown. But if you are curious/interested in this stuff i could send you a .zip with the software and some demo files for easier demo sounds than the ones you used for this vid (like playing actuall 400Hz tones or really perfect fifths ;) ). Have a nice day and stay save :)

[@chiaramartin8426]

Sounds interesting!! Could u send the .zip to me?

[@VRchitecture]

Did you try live coding with SoundPi, SuperCollider or sth like that? I guess with such background you should do really well in tweaking stuff in realtime )

[@Testgeraeusch]

@@VRchitecture I'm seriously considering just abusing a pico for that; didn't find the time though. But i borrowed a friends touchscreen once for a live performance on an t+-integrated virtual microkeyboard where i could only press one key at a time, so it's getting there XD still no real time manipulation, but one could type in the instrument definitions as you play and the new notes use the new parameters. It was just inteded as a quick testing feature, but it is possible to perform with that... ^^

[@tobitdesmet]

Lol I would love to have that software! I'm really into microtonal stuff (due to Jacob Collier 😏) but all regular programs are too grid-based for that. I would love to be able to use something like this!

[@jwgmail]

what is the name of the java program?

[@SilentShiba]

Dude you crushed it. The visuals really made it easy to learn, and I liked listening to the song you made at the end.

[@EnderMega]

This is incredible, the "editing" since you made the graphics library, the story telling, the content in it, everything was awesome.

[@antipainK]

Wow, you explained it far better than anyone else! I needed this kind of scientific explanation of music, all other people talk about "rules" and that "you have to feel it, just redo it over and over and you'll get it". This filled the empty space in my soul 😍

[@melihbostan9159]

I also needed this explanation and I feel smarter for understanding this. I guess we are all geniuses with a right teacher :)

[@BlessedCobra]

This is beautiful. I’ve always wondered how music is mathematically structured-especially electronic music-and this video offers a brief yet clear introduction of the core concepts. And the culmination of everything we learned at the end with all the waves coming together genuinely brought tears to my eyes. Thank you.

[@Brotyx]

wow, I love the fact that this video is so detailed and explains everything so well! I normally don't leave comments on videos, but I really feel like I should do it here for the algorithm! :)

Man, this is absolutely golden. I've been looking for a video like this for ages

[@thebaconbreadful]

This gave me such better understanding of music it is crazy! It just immediately clicked with me thinking about how our brains superpower is abstraction. It also finally made a lot of sense that culture impacts our musical understanding and preference. Especially why the rough integer approximation in a triard is working if you consider western music theroy. I would love a follow up video talking about a few of those things. Awesome work! It really inspired me and probably will help me understand many more things in the future.

[@fireemblem2770]

Glad this stumbled upon me, I have always wanted to learn about the mathematics of music, not just the addition needed in notes but stuff like this. Thank you!!

[@seekerofmeaning]

The way you explain that is clean like a professional mix ;) Thank You!

[@hvandermillen3237]

Man, I have seen so many people try to explain this, but you did it the best by far. Specifically I was always confused about how the square, triangle, etc. waves could be the "sum" of a bunch of sinusoids, it didn't really make sense looking at the shape. But this video paired with the calculus class I am taking really helped me understand where that comes from. Thank you so much!
