# Web Audio Track

This is an easy to use plugin that enables you to record and play back a single track of audio.  You can also load audio from a url and concatenate audio from recorded sounds and external audio files into a single audio track.

#### [Click here](https://danielstorey.github.io/WebAudioTrack/index.html) for the demo

```

var audioTrack = new WebAudioTrack()
