\subsection{Detailed Description}
Audio\-Copy 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 {\bf Audio\-Sample} {\rm (p.\,\pageref{class_audio_sample})} 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.
