Example usage of Web Audio API

main.js

define(['audio'], function (audio) {
    
    var mp3s = {
        'track1': 'foo/bar/1.mp3',
        'track2': 'foo/bar/1.mp3',
        'track3': 'foo/bar/1.mp3'
    };

    audio.init(mp3s, function() {
        // this callback will fire when all the mp3s
        // have been preloaded and are ready to play
        // (so perhaps a loading animation can be removed)
        //
        // you could then call audio.startAll(shouldMute)
        // (which will begin all tracks simultaneously, optionally muted)
        //
        // or you could call audio.toggleTrack('track2')
        // which will mute/unmute a given track
    });
    
});
