What about audio?

[1j01]

how about... ✨ audio 🔉 ~!

Like html5bytebeat (note: link plays sound), but with Shadershop's GUI for editing waveforms.
Or Shadertoy, which has audio shaders. But, you know, combined with Shadershop.

It would probably be good to have different views... like a view that's synced with the what you hear, in addition to the one you use to manipulate the wave function.

📦 audio-shader? could be useful, maybe
