How do Shadertoy's audio shaders work?
<p>To start off, I couldn't really find any appropriate community to post this question in so I picked this one. I was wondering how the audio shaders of the popular webGL based shader tool worked, because when, even though I had obviously heard of 'normal' GLSL shaders, I first heard of shaders for procedurally generating audio, I was amazed. Any clues?</p>
