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	X-axis component of early reflections panning vector
y	Y-axis component of early reflections panning vector
z	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	X-axis component of late reverberation panning vector
y	X-axis component of late reverberation panning vector
z	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	(0.04 / 4.0 / 0.25 in sec) Modulation time
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
