Detailed Description

AudioCopy is used for certain kinds of stream join operations.fill an audio sample frame from another.

Essentially it fills the current sample buffer from another AudioSample object and requests a new object thru a virtual every time it empties. This is used in dtmf dialing, for example, to fill in the next digit tone.
