Members

fDecayHFRatio
Ratio of the decay time at high frequencies to the decay time at low frequencies, in the range 0.1 to 2. The default value is 0.83.
fDecayTime
Decay time, in the range 0.1 to 20 seconds. The default value is 1.49 seconds.
fDensity
Modal density in the late reverberation decay. The default value is 100.0 percent. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_DENSITY enumeration.
fDiffusion
Echo density in the late reverberation decay. The default value is 100.0 percent. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_DIFFUSION enumeration.
fHFReference
Reference high frequency. The default value is 5000.0 Hz. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_HFREFERENCE enumeration.
fReflectionsDelay
Delay time of the first reflection relative to the direct path, in the range 0 to 0.3 seconds. The default value is 0.007 seconds.
fReverbDelay
Time limit between the early reflections and the late reverberation relative to the time of the first reflection, in the range 0 to 0.1 seconds. The default value is 0.011 seconds.
fRoomRolloffFactor
Rolloff factor for the reflected signals. The default value is 0.0. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_ROOMROLLOFFFACTOR enumeration. The rolloff factor for the direct path is controlled by the DirectSound listener.
lReflections
Attenuation of early reflections relative to lRoom. The default value is -2602 mB. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_REFLECTIONS enumeration.
lReverb
Attenuation of late reverberation relative to lRoom. The default value is -200 mB. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_REVERB enumeration.
lRoom
Attenuation of the room effect. The default value is -1000 mB. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_ROOM enumeration.
lRoomHF
Attenuation of the room high-frequency effect. The default value is 0 mB. Minimum and maximum values are defined in the CONST_DSFX_I3DL2REVERB_ROOMHF enumeration.
