class UReverbEffect : public UObject

Variables

Type	Name	Description
float	AirAbsorptionGainHF	Air Absorption - 0.0 < 0.994 < 1.0 - lower value means more absorption
bool	bBypassEarlyReflections	Bypasses early reflections
bool	bBypassLateReflections	Bypasses late reflections.
uint32: 1	bChanged	Transient property used to trigger real-time updates of the reverb for real-time editor previewing
float	DecayHFRatio	Decay High Frequency Ratio - 0.1 < 0.83 < 2.0 - how much the quicker or slower the high frequencies decay relative to the lower frequencies.
float	DecayTime	Decay Time - 0.1 < 1.49 < 20.0 Seconds - larger is more reverb
float	Density	Density - 0.0 < 1.0 < 1.0 - Coloration of the late reverb - lower value is more grainy
float	Diffusion	Diffusion - 0.0 < 1.0 < 1.0 - Echo density in the reverberation decay - lower is more grainy
float	Gain	Reverb Gain - 0.0 < 0.32 < 1.0 - overall reverb gain - master volume control
float	GainHF	Reverb Gain High Frequency - 0.0 < 0.89 < 1.0 - attenuates the high frequency reflected sound
float	LateDelay	Late Reverb Delay - 0.0 < 0.011 < 0.1 Seconds - time difference between late reverb and first reflections
float	LateGain	Late Reverb Gain - 0.0 < 1.26 < 10.0 - gain of the late reverb
float	ReflectionsDelay	Reflections Delay - 0.0 < 0.007 < 0.3 Seconds - the time between the listener receiving the direct path sound and the first reflection
float	ReflectionsGain	Reflections Gain - 0.0 < 0.05 < 3.16 - controls the amount of initial reflections
float	RoomRolloffFactor	Room Rolloff - 0.0 < 0.0 < 10.0 - multiplies the attenuation due to distance
