Sound language compiling to WASM

Designed to be useful for writing sound formulas / audio processing code for various audio targets, such as AudioWorkletProcessor, audio engines, individual audio nodes etc.

Initially inspired by zzfx, bytebeat, hxos, web-audio-engine and others, but soon it became clear that JS limitations are no-go for sound processing and it needs something more foundational with better low-level control, which WASM perfectly provides.

Examples

Encoding Video

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

/**
 * An utility function to create views. Views are objects that abstract the DOM.
 *
 * It's a very thin layer that will allow to write frontend tests if
 * needed and get rid of jQuery
 *
 * The idea of this function is to reduce boilerplate: instead of creating
 * by hand the elements we need with jQuery, we just provide the selectors
 * and it returns an object with the same shape.
