Webgl-based audio processing stream.
var AudioShader = require('audio-shader');
var Speaker = require('audio-speaker');
//Create shader stream based on sound processing function
AudioShader(`
vec2 mainSound( float time ){
return vec2( sin(6.2831*880.0*time)*exp(-3.0*time) );
}
`)
//Send generated sound to speaker
.pipe(Speaker());
API
API is fully compatible with shadertoy to copy-paste and run it’s code locally. Note that shadertoy limits output sound to 60s
, whereas audio-shader runs till it is stoped.
It also might be found helpful to use glslify to get code inserted neatly:
//index.js
var Shader = require('audio-shader');
var Speaker = require('speaker');
var glslify = require('glslify');
Shader(glslify('./sound.glsl'), options?).pipe(Speaker());
//sound.glsl
vec2 mainSound( float time ){
return vec2( sin(6.2831*440.0*time)*exp(-3.0*time) );
}
Audio-shader can also be used as a processing stream. It inherits audio-through, which is basically a transform stream, so it can be used with other node streams.
var MusicXML = require('musicxml-to-pcm');
var Processor = require('audio-shader');
var Speaker = require('speaker');
MusicXML()
.pipe(Processor(`
vec2 main (float time) {
//TODO test this example and document it, shadertoy is down
return vec2();
}
`))
.pipe(Speaker());
