+SysVAD Virtual Audio Device Driver Sample
+========================================
 
 The Microsoft SysVAD Virtual Audio Device Driver (SYSVAD) shows how to develop a WDM audio driver that exposes support for multiple audio devices.

+DelayAPO | Sample APO that adds a delay to the input samples.
+KwsAPO | Sample APO that uses KSPROPERTY_INTERLEAVEDAUDIO_FORMATINFORMATION to determine if the keyword spotter pin is interleaving loopback audio with the microphone audio and identify which channels contain loopback audio. If it is interleaved the APO will strip out the loopback audio and deliver only the microphone audio upstream. Because channel data is removed, the APO negotiates an output format which is different than the input format.
