Depends what point on the spectrum you refer to by "how". Implementation, creativity, or the focus and discipline required to combine the two? :P
I had a quick look; as always with the presentations on this website, all the un-minified JavaScript is right there for you to pour over: https://ciechanow.ski/js/sound.js
So that covers the implementation: a giant pile of WebGL to power the rotatable boxes and animate effectively using the GPU, alongside in this case a bunch of Web Audio code.
Unfortunately that doesn't cover the focus/discipline part, which I would definitely appreciate some pointers on... one of these days I'll find some that fit within my ADHD address space xD
