This allows the implementation of just-in-time streaming scenarios; the client can keep the absolute minimum data queued on the voice at all times, and pass it fresh data just before the data is required. This model provides the lowest possible latency attainable with XAudio2. For xWMA and XMA data BytesRequired will always be zero, since the concept of a frame of xWMA or XMA data is meaningless. Note In a situation where there is always plenty of data available on the source voice, BytesRequired should always report zero, because it doesn't need any samples immediately to avoid glitching. </param>
