Constants

eAVDecDDOperationalMode_NONE

No dynamic range control or dialogue normalization (dialnorm). This mode should be used only for signal tests.

eAVDecDDOperationalMode_LINE

Line mode. Dialnorm is enabled with a reference level of -31 decibels full scale (dBFS). Dynamic range control is applied, and high-level/low-level scaling is enabled. To set the high-level scaling factor, set the AVDecDDDynamicRangeScaleHigh property. To set the low-level scaling factor, set the AVDecDDDynamicRangeScaleLow property.

eAVDecDDOperationalMode_RF

RF mode. Dialnorm is enabled with a reference level of -20 dBFS. Dynamic range control is applied. High-level/low-level scaling is disabled; instead, the maximum dynamic range reduction is applied.

eAVDecDDOperationalMode_CUSTOM0

Custom mode 0 (analog dialnorm).

eAVDecDDOperationalMode_CUSTOM1

Custom mode 1 (digital dialnorm).
