Audio-ISSUE-31 (activeSourceCount): AudioContext.activeSourceCount [Web Audio API]

Raised by: Philip Jägenstedt
On product: Web Audio API

https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#dfn-activeSourceCount

"currently playing" is not sufficiently defined.

Possibly, is it the number of AudioBufferSourceNodes with playbackState == PLAYING_STATE. However, which AudioBufferSourceNodes? After creating them, the spec doesn't define any association with the AudioContext, so it's not clear how to count them.

Seemingly, only AudioBufferSourceNodes are included in the count, but given the name including Oscillator and MediaElementAudioSourceNode ought to also be included, given that they also have playing states (directly or indirectly).

Finally, what is the use case for activeSourceCount? If it can be dropped, the above issues become moot.
