Int32 RecomendedBufferSize
To ensure skip free recording an playback, audio buffers must have some minimum size.
Returns: Int32 - Recommended buffer size in bytes
Remarks:
The size depends upon sampling frequency, quantization, and number of channels. The function will return buffer size (byte count) being power of two and at least 0.2 second long. This value can be directly assigned to the BufferSize property.
