Since the API makes no reference to AudioSource or any client classes, perhaps
it's named too narrowly. How about just calling it AudioStream?

Done
I don't think we will want to use the same interface on both sides, of the
connection. But for now it doesn't matter as we won't need AudioReceiveStream
anytime soon.  AudioStream is also more consistent with VideoStream.
