Chapter 11: Reverb One 101
Decay Ratio Controls the ratio by which reverb
time is increased when a signal is above or below
the Threshold level. Dynamics behavior differs
when the Decay Ratio is set above or below 1. A
ratio setting of greater than 1 increases reverb
time when the signal is above the threshold. A
ratio setting of less than 1 increases a reverb’s
time when the signal is below the threshold.
For example, if Decay Ratio is set to 4, the reverb
time is increased by a factor of 4 when the signal
is above the threshold level. If the ratio is 0.25,
reverb time is increased by a factor of 4 when
the signal is below the Threshold level.
Threshold Sets the input level above or below
which reverb decay time will be modified.
Chorus Controls
The Chorus section has controls for setting the
depth and rate of chorusing applied to a reverb
tail. Chorusing thickens and animates sounds
by adding a delayed, pitch-modulated copy of
an audio signal to itself.
Chorusing produces a more ethereal or spacey
reverb character. It is often used for creative ef-
fect rather than to simulate a realistic acoustic
environment.
Depth Controls the amplitude of the sine wave
generated by the LFO (low frequency oscillator)
and the intensity of the chorusing. The higher
the setting, the more intense the modulation.
Rate Controls pitch modulation frequency. The
higher the setting, the more rapid the chorus-
ing. Setting the Rate above 20 Hz can cause fre-
quency modulation to occur. This will add side-
band harmonics and change the reverb’s tone
color, producing some very interesting special
effects.
Reverb Controls
The Reverb section has controls for the various
reverb tail parameters, including level, time, at-
tack, spread, size, diffusion, and pre-delay. These
determine the overall character of the reverb.
Level Controls the output level of the reverb tail.
When set to 0%, the reverb effect consists en-
tirely of the early reflections (if enabled).
Time Controls the rate at which the reverbera-
tion decays after the original direct signal stops.
The value of the Time parameter is affected by
the Size parameter. You should therefore adjust
To hear examples of reverb tail chorusing,
load one of the Chorus presets with the Li-
brarian.
