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.

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.

For more information on dynamic range control, see the Web article Windows Media Audio Professional Codec Features.
