The ACX_MICROPHONE_CONFIG structure is used to configure a microphone.
The size of all of the data in the ACX_MICROPHONE_CONFIG structure in bytes.
A combination of values from the ACX_MICROPHONE_CONFIG_FLAGS enum that describe the microphone.
A 16.16 fixed point decibel (dB) value specifying the microphone's signal-to-noise ratio. Setting this to LONG_MIN_VALUE means that this field is unsupported.
A 16.16 fixed point decibel (dB) value specifying the microphone's sensitivity. Setting this to LONG_MIN_VALUE means that this field is unsupported.
An optional ACX_MIC_ARRAY_GEOMETRY structure that describes the geometry of the microphone if it is a microphone array.
An optional pointer to an ACX_INTERLEAVED_AUDIO_FORMAT_INFORMATION structure that specifies how loopback audio is interleaved with the microphone audio.
The ACX_MICROPHONE_CONFIG structure should be assigned to the MicrophoneConfig member of the ACX_PIN_CONFIG structure and AcxPinConfigMicrophoneConfigSpecified should be included in the Flags member of the ACX_PIN_CONFIG structure.
To initialize an ACX_MICROPHONE_CONFIG structure, your driver should call ACX_MICROPHONE_CONFIG_INIT.
Minimum ACX version: 1.0
