Remarks

Noise filling adds a small amount of noise to portions of the signal where center clipping has removed the residual echoes. This results in a better experience for the user than leaving silent gaps in the signal.

This property can have the following values.

Value Description
VARIANT_TRUE Enable noise filling.
VARIANT_FALSE Disable noise filling.

 

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.
