Stereo Reverb
Reverberation is a simulation of a natural space such as a room or hall. The stereo reverb
algorithm is designed to simulate various halls, rooms and reverberation plates.
Decay time defines the time it takes for the reflected sound from the room to decay or die away.
The diagram below shows a generalized reverberation envelope.
After a short pre-delay period, the echoes from the closest walls or ceiling are heard. These first
echoes, or early reflections, vary greatly depending on the type of room. Some time after the
early reflection cluster ends (late reverb delay), the late reverberation (a dense cloud of
complex wall reflections) begins and decays according to the time set by the Decay Time
parameter.
Diffusion is the amount of scattering and density of the late reverberation cloud. Rooms with
many complex surfaces have more diffusion than bare rooms.
High frequency energy tends to fade away first as a sound is dissipated in a room. The High
Frequency Damping parameter adjusts the time it takes for the high frequency energy to die
away and thus changes the characteristics of the room. Rooms with smooth, hard surfaces are
more reflective and have less high frequency damping. Rooms filled with sound absorbing
materials, such as curtains or people, have more high frequency damping.
The Low Frequency Damping parameter adjusts the time it takes for the low frequencies to die
away. This control adjusts the “boominess” of the room.
Parameter Description
Decay Time Sets the length of the Late Reverb. Range 1.5 to 30seconds
Early Reflections Level Sets the volume of the initial wall reflections.
Range: 0% to 100%
Early/Late Reverb Bal Adjusts the balance between early refections and late reverb.
Range: 0% to 100%
Late Reverb Delay Sets the time between early reflections and the onset of the late
reverb cloud. Range: 1ms to 350ms
Diffusion Sets the amount of scattering of the late reverb cloud.
Range: 0% to 100%
High Freq. Damping Sets the rate at which high frequencies die away.
Range: -10.0 to +3.0 damping factor
Low Freq. Damping Sets the rate at which low frequencies die away.
Range: -10.0 to +3.0 damping factor
