Play back audio data stored in an AudioBuffer
summary (oneliner)
Typically connected to a Ops.WebAudio.AudioBuffer, which holds the sample / audio file.
In contrast to the Web Audio AudioBufferSourceNode, which can only play back an AudioBuffer once, this op can play back multiple times (every time the playback finished a new AudioBufferSourceNode is being created internally).

Inputs
The audio buffer (typically from an audio file) which contains the audio data. In most cases you need to create a AudioBuffer op to load your audio sample and connect it to this port.
Playback Controls
When set the playback is started
When set to true the sound will start to play as soon as the AudioBuffer is loaded.
Weather or not the playback should start from the beginning once the end has been reached. Please note that some browsers have problems doing a perfect loop with certain file types. If you e.g. use an MP3-file as AudioBuffer Google Chrome might produce a slight gap between the loops. Ogg-files sometimes work better.
