<hr><a name="_details"></a><h2>Detailed Description</h2>
<a class="el" href="classost_1_1_audio_copy.html">AudioCopy</a> is used for certain kinds of stream join operations. fill an audio sample frame from another.
<p>
Essentially it fills the current sample buffer from another <a class="el" href="classost_1_1_audio_sample.html">AudioSample</a> 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.
