IMiniportWaveRTInputStream interface (portcls.h)

The IMiniportWaveRTInputStream interface represents the input wave stream that flows through a pin on the KS filter that wraps a WaveRT rendering or capture device. IMiniportWaveRTInputStream inherits from the IUnknown interface.

A driver can implement this interface for better coordination of audio dataflow from the driver to OS. If this interface is available on a capture stream, the OS uses methods on this interface to access data in the WaveRt buffer. IMiniportWaveRTInputStream is supported in Windows 10 and later.
