Source

A Source represents audio you can play back. You can do interesting things with Sources, like set the volume, pitch, and its position relative to the listener. Please note that positional audio only works for mono (i.e. non-stereo) sources.

The Source controls (play/pause/etc) act according to the following state table.

	Stopped	Playing	Paused
play()	Play	No change	Play
stop()	No change	Stop + Rewind	Stop + Rewind
pause()	No change	Pause	No change
resume()	No change	No change	Play
rewind()	No change	Rewind + Play	Rewind + Pause

And for fans of flowcharts (note: omitted calls have no effect, rewind does).
