Reverb Presets Library

Reverb Presets Library

The Reverb Presets Library can be found in the DataBase View and contains Reverb Sound Entity scene objects. 

The presets can be accessed through a Reverb Volume Entity (see the tutorial here). 


 

Tools


 

Add Preset 
Adds a new Reverb Preset 
Remove Preset 
Removes the selected Reverb Preset 
Preview Preset 
Plays a sample sound (Editor/Sounds/) with current preset reverb settings (see s_mpegcompression) 

 

Preset Window

The Preset Window contains all the reverb presets of the game. 

You can access the parameters for a Reverb Preset by clicking on it. 

Parameters Window

The parameters are derived mainly from the I3DL2 specification which can be found on IASIG.org or in FMOD help. In some reverb implementations some parameters are completely ignored. Numbers describe min, max, and default values. All intensity levels or relative attenuations are expressed in hundredths of decibels (millibels, mB). All times are expressed in seconds. 

 

nEnvironment 
(-1 / 25 / -1) Sets all listener properties by preset. -1 = OFF. 
fEnvSize 
(1.0 / 100.0 / 7.5 in m) Environment size 
fEnvDiffusion 
(0.0 / 1.0 / 1.0) Environment diffusion 
nRoom 
(-10000 / 0 / -1000 in mB) Room effect level for both early reflections and late reverberation (at mid frequencies) 
nRoomHF 
(-10000 / 0 / -100 in mB) Relative room effect level at high frequencies 
nRoomLF 
(-10000 / 0 / 0 in mB) Relative room effect level at low frequencies 
fDecayTime 
(0.1 / 20.0 / 1.49 in sec) Reverberation decay time at mid frequencies 
fDecayHFRatio 
(0.1 / 2.0 / 0.83) High-frequency to mid-frequency decay time ratio 
fDecayLFRatio 
(0.1 / 2.0 / 1.0) Low-frequency to mid-frequency decay time ratio 
nReflections 
(-10000 / 1000 / -2602 in mB) Early reflections level relative to room effect 
fReflectionsDelay 
(0.0 / 0.3 / 0.007 in sec) Initial reflection delay time 
fReflectionsPan 
 
X-axis component of early reflections panning vector 
Y-axis component of early reflections panning vector 
Z-axis component of early reflections panning vector 
nReverb 
(-10000 / 2000 / 200 in mB) Late reverberation level relative to room effect 
fReverbDelay 
(0.0 / 0.1 / 0.011 in sec) Late reverberation delay time relative to initial reflection 
fReverbPan 
 
X-axis component of late reverberation panning vector 
X-axis component of late reverberation panning vector 
X-axis component of late reverberation panning vector 
fEchoTime 
(0.075 / 0.25 / 0.25 in sec) Echo time 
fEchoDepth 
(0.0 / 1.0 / 0.0) Echo depth 
fModulationTime

fModulationDepth 
(0.0 / 1.0 / 0.0) Modulation depth 
fAirAbsorptionHF 
(-100 / 0.0 / -5.0 in mB) Change in level per meter at high frequencies 
fHFReference 
(1000.0 / 20000 / 5000.0 in Hz) Reference high frequency 
fLFReference 
(20.0 / 1000.0 / 250.0 in Hz) Reference low frequency 
fRoomRolloffFactor 
(0.0 / 10.0 / 0.0) Like rolloffscale in System::set3DSettings but for reverb room size effect 
fDiffusion 
(0.0 / 100.0 / 100.0) Value that controls the echo density in the late reverberation decay 
fDensity 
(0.0 / 100.0 / 100.0) Value that controls the modal density in the late reverberation decay 
nFlags 
Modifies the behavior of above properties, do not change this 
sTailName 
Used to specify a special gunshot tail name for that reverb. Currently disabled
