MFPKEY_WMADEC_DRCMODE Property

Specifies the dynamic range control mode that the audio decoder will use.

Constant for IPropertyBag

g_wszWMACDRCSetting

Data Type

VT_I4

Default Value

0

Remarks

This integer value ranges from 0 to 2. The greater the value, the smaller the dynamic range of the uncompressed audio output. A value of 0 signals the codec to perform no dynamic range control, that is, the codec will not alter the inherent dynamic range of the encoded content.

If this value is set to 1 or 2, the codec will use the following properties to determine the needed dynamic range control:

• MFPKEY_WMADRC_AVGREF
• MFPKEY_WMADRC_PEAKREF
• MFPKEY_WMADRC_AVGTARGET
• MFPKEY_WMADRC_PEAKTARGET

If you do not provide target values, the codec will provide its own.

Requirements

Minimum supported client	Windows XP
Minimum supported server	Windows Server 2003
