openmusic-sample-player

Provides an abstraction on top of BufferSourceNodes so samples can be played without regenerating the node when ended

Usage

Install first: npm install openmusic-sample-player.

Then you can use it in your code:

var SamplePlayer = require('openmusic-sample-player');

var audioContext = new AudioContext();
var player = SamplePlayer(audioContext);

// suppose you have a BufferSource in `buffer` already

player.buffer = buffer;

// if you want to make it loop
player.loop = true;

// and start playing!
player.start();

Multiple plays can be scheduled:

var now = audioContext.currentTime;
player.start(now + 1); // play in 1 second
player.start(now + 2); // play in 2 seconds
player.start(now + 3); // play in 3 seconds
// ...
player.stop(); // stop all scheduled plays

Attributes

Each instance of SamplePlayer has some attributes you can access:

loop (Boolean)

loopStart (Number)

loopEnd (Number)

pitchBend (AudioParam)

Demo

Run npm install so it installs stuff for the demo. Then gulp build, and then you can open build/index.html for the demo.

If you do changes in the code, you'll need to rebuild the demo. Use gulp build or gulp only for running build and setting up a watch loop that automatically rebuilds the demo as you change its files.
