Getting Started

1. npm install audiosynth
2. var AudioSynth = require('audiosynth');

Usage

var AudioContext = window.AudioContext || window.webkitAudioContext;

var context = new AudioContext();
var synth = new AudioSynth(context);

// Default oscillator wave is sawtooth

synth.setOscWave(0); // Sine Wave
synth.setOscWave(1); // Square Wave
synth.setOscWave(2); // Sawtooth Wave
synth.setOscWave(3); // Triangle Wave

// function(MIDINote, amplitude, filterOffset, currentTime)
synth.playNote(69, 1.0, 1.0, 0);

// Turn up stereo delay
synth.setDelayFeedback(0.5); 

// Set delay time to tempo
synth.setDelayTimeTempo(110, 0.25);

// Set notes using traditional note names
synth.playNote(synth.noteToMIDI('A', 4), 1.0, 1.0, 0);

// Set filter cuttoff
synth.setFilterCutoff(0.2);

// Increase amplitude release time
synth.setAmpReleaseTime(0.7);

// Set filter envelope modulation amount
synth.setFilterEnvMod(0.8);

// Set filter attack time
synth.setFilterAttackTime(0.6);

// And so on
