MFPKEY_WMADRC_AVGTARGET Property
Specifies the desired average volume level of output audio content.
Constant for IPropertyBag
g_wszWMADRCAverageTarget
Data Type
VT_I4
Default Value
See Remarks.
Remarks
You can set this value on the decoder for the purpose of dynamic range control, but it will have an effect only if the MFPKEY_WMADEC_DRCMODE property is set.
Note
Setting the average target value is not recommended. Adjusting the average value does not affect the difference between loud and soft sounds. Instead, it cuts or boosts the overall average volume which may cause undesirable distortion during playback.
If you request dynamic range control from the decoder when this property is not set, the codec will compute a default value.
Use the MFPKEY_WMADRC_AVGREF and MFPKEY_WMADRC_PEAKREF properties to compute appropriate values for this property.
