An audio track can be created like so:

var audioTrack = new WebAudioTrack()

This creates a single track of audio. For more than one track, or source simply construct multiple instances e.g.

var microphoneTrack = new WebAudioTrack();
var mp3Track = new WebAudioTrack();

You can then use the methods below to record and playback audio.
