    openmusic-array-to-audiobuffer

    Handy function to generate Web Audio Buffers given an array of sample data

    Usage

    Given some audio sample data in an array, you want to convert it into a buffer that can be assigned to a BufferSource node. This is how you do this:

    var arrayToAudioBuffer = require('openmusic-array-to-audiobuffer');
    var audioContext = new AudioContext();
    var sampleData = makeWhiteNoise(44100);
    var buffer = arrayToAudioBuffer({
        context: audioContext,
        data: sampleData
    });
    var bufferSource = audioContext.createBufferSource();
    bufferSource.buffer = buffer;
    bufferSource.connect(audioContext.destination);
    bufferSource.start();

    See demo/main.js for a working example.
