This property can have the following values.

Value	Description
VARIANT_FALSE	Disable center clipping.
VARIANT_TRUE	Enable center clipping.

The default value of this property is VARIANT_TRUE (enabled). Before setting this property, you must set the MFPKEY_WMAAECMA_FEATURE_MODE property to VARIANT_TRUE.

The DSP uses this property only when AEC processing is enabled.
