Parameter
lRoom
Attenuation of the room effect, in millibels (mB), in the range from -1000 to 0. The default value is
-1000 mB.

lRoomHF
Attenuation of the room high-frequency effect, in mB, in the range from -1000 to 0. The default value is -100 mB.

flRoomRolloffFactor
Rolloff factor for the reflected signals, in the range from 0 to 10. The default value is 0.0. The rolloff factor for the direct path is controlled by the DirectSound listener.

flDecayTime
Decay time, in seconds, in the range from 0.1 to 20. The default value is 1.49 second.

flDecayHFRatio
Ratio of the decay time at high frequencies to the decay time at low frequencies, in the range from 0.1 to 2. The default value is 0.83.

lReflections
Attenuation of early reflections relative to lRoom, in mB, in the range from -10000 to 1000. The default value is -2602 mB.

flReflectionsDelay
Delay time of the first reflection relative to the direct path, in seconds, in the range from 0 to 0.3. The default value is 0.007 seconds.

lReverb
Attenuation of late reverberation relative to lRoom, in mB, in the range -from -1000 to 2000. The default value is 200 mB.

flReverbDelay
Time limit between the early reflections and the late reverberation relative to the time of the first reflection, in seconds, in the range from 0 to 0.1. The default value is 0.011 seconds.

flDiffusion
Echo density in the late reverberation decay, in percent, in the range from 0 to 100. The default value is 100.0 percent.

flDensity
Modal density in the late reverberation decay, in percent, in the range from 0 to 100. The default value is 100.0 percent.

flHFReference
Reference high frequency, in hertz, in the range from 20 to 20000. The default value is 5000.0 Hz.

lQuality
Quality of the effect, in the range from 0 to 3. The default value is 2.

No Return Value
