Type: UINT32 Read: InputLevel calculated for the input to the compressor, in u8.23 format (-0x0000_0000 to 0x7FFF_FFFF). The eight integer bits allow the equalizer section to have a gain of up to 48 dB prior to the compressor, without clipping. compGainReduction
Type: UINT32 Read: Calculated attenuation for the compressor, in u1.23 format (-0x00_0000 to 0x80_0000). This is a linear multiplier; a value of 0x40_0000, which corresponds to 0.5, is a gain of -6 dB or a gain reduction of 6 dB. Reserved4
Type: UINT32 Reserved. compGain

Type: UINT32 Reserved. compRelease
Type: UINT32 Write: Release rate for the compressor, in u1.23 format (-0x00_0001 to 0x80_0000). This is the amount by which compGainReduction is incremented for each sample period when the compressor/expander is in the release phase. If compLogGain is set, compRelease is shifted right to align bit 23 with the most significant bit of the current value of compGainReduction; this causes the increment to be exponential. The value 0 is not valid for this member and will cause incorrect operation. Reserved7
Type: UINT32 Reserved. compExpand
Type: UINT32 Write: Refer to SHAPE_EQCOMP_EXPAND_MODE. compLogGain
Type: UINT32 Write: Refer to SHAPE_EQCOMP_LOG_GAIN. This causes the attack and release phases to decrement and increment the gain reduction exponentially, to make it linear in logarithmic space; that is, linear in dB. compSidechainMode
Type: UINT32 Write: Refer to SHAPE_EQCOMP_SIDECHAIN_MODE. compMode
Type: UINT32 Write: Refer to SHAPE_EQCOMP_COMPRESSOR_MODE. compEnable
Type: UINT32 Write: 1 == enabled, 0 == disabled. compThreshold
Type: UINT32 Write: Threshold value, in u1.23 format (-0x00_0000 to 0x80_0000). Reserved8
Type: UINT32 Reserved. compAttack
Type: UINT32 Write: Attack rate for the compressor, in u1.23 format (-0x00_0001 to 0x80_0000). This is the amount by which compGainReduction is decremented for each sample period when the compressor/expander is in the attack phase. If compLogGain is set, compAttack is shifted right to align bit 23 with the most significant bit of the current value of compGainReduction; this causes the increment to be exponential. The value 0 is not valid for this member and will cause incorrect operation. Reserved9
Type: UINT32 Reserved. compOneOverRatio
Type: UINT32 Write: Slope for the compressor, in u1.15 format (-0x0000 to 0x8000). This is the reciprocal of the traditional ratio control on compressors. For a ratio of 1:1, set compOneOverRatio to 0x8000. For a ratio of 4:1, set compOneOverRatio to 0x2000. The value 0x0000 is a ratio of infinite:1. compGainTarget
Type: UINT32 Write: User-settable target for the output (makeup) gain. During one audio frame, the gain will ramp from the current value to compGainTarget, in u3.13 format (-0x0000 to 0xFFFF).
