Diffusion
Diffusion sets the degree to which initial echo
density increases over time. High settings result
in high initial build-up of echo density. Low set-
tings cause low initial buildup. This control in-
teracts with the Size and Decay controls to affect
the overall reverb density. High settings of diffu-
sion can be used to enhance percussion. Use low
or moderate settings for clearer and more natu-
ral-sounding vocals and mixes.
Decay
Decay controls the rate at which the reverb de-
cays after the original direct signal stops. The
value of the Decay setting is affected by the Size
and Algorithm controls. This control can be set
to infinity on most algorithms for infinite re-
verb times.
Pre-Delay
Determines the amount of time that elapses be-
tween the original audio event and the onset of
reverberation. Under natural conditions, the
amount of Pre-Delay depends on the size and
construction of the acoustic space, and the rela-
tive position of the sound source and the lis-
tener. Pre-Delay attempts to duplicate this phe-
nomenon and is used to create a sense of
distance and volume within an acoustic space.
Long Pre-Delay settings place the reverberant
field behind rather than on top of the original
audio signal.
Hi Frequency Cut
Hi Frequency Cut controls the decay character-
istic of the high frequency components of the
reverb. It acts in conjunction with the Low-Pass
Filter control to create the overall high fre-
quency contour of the reverb. When set rela-
tively low, high frequencies decay more quickly
than low frequencies, simulating the effect of air
absorption in a hall. The maximum value of this
control is Off (which effectively means bypass).
Low-Pass Filter
Low-Pass Filter controls the overall high fre-
quency content of the reverb by setting the fre-
quency above which a 6 dB per octave filter at-
tenuates the processed signal. The maximum
value of this control is Off (which effectively
means bypass).
Dynamics II
There are five types of DigiRack Dynamics pro-
cessors: Compressor, Limiter, Gate, Ex-
pander/Gate and DeEsser.
