Remarks
The value of this property is a KSAUDIO_MIC_ARRAY_GEOMETRY structure. This structure is defined in the header file KsMedia.h. To get the microphone array geometry, query the audio device for the KSPROPERTY_AUDIO_MIC_ARRAY_GEOMETRY property by calling the IKsControl::KSProperty method on the device. For more information on microphone arrays, download the white paper How to Build and Use Microphone Arrays for Windows Vista.
Set this property if you are using the DSP in filter mode and microphone array processing is enabled. If you are using the DSP in source mode, the DSP automatically queries the device for the geometry information.
