Chorus - DigiDesign DigiRack Plug-ins Manual

Chorus

Chorus adds a shimmering quality to audio ma-
terial by combining a time-delayed, pitch-
shifted copy of an audio signal with itself.
The Chorus plug-in was formerly called
D-fx Chorus. It is fully compatible with all
settings and presets created for D-fx Chorus.

Gain Adjusts the input volume of the chorus to
prevent clipping or increase the level of the pro-
cessed signal. This slider is set to a default of
+3 dB. If your source audio has been recorded
very close to peak level, this +3 dB default set-
ting could cause clipping. Use this control to re-
duce the input level.
Selecting the Sum Input button sums the dry in-
put signals (mono or stereo) before processing
them. The dry signal then appears in the center
of the stereo field and the wet, effected signal
will be output in stereo.
When the Sum Inputs button is selected, the
LFO waveform on the right channel is automat-
ically phase inverted to enhance the mono-ste-
reo effect.

Mix Adjusts the balance between the effected
signal and the original signal and controls the
depth of the effect. Mix is adjustable from 0% to
100%.
Low-Pass Filter Controls the cutoff frequency of
the Low-Pass Filter. Use this to attenuate the
high frequency content of the feedback signal.
The lower the setting, the more high frequen-
cies are removed from the feedback signal.
The range of the Low-Pass Filter is 20 Hz to
19.86 kHz, with a maximum value of Off (which
effectively means bypass).
Delay Sets the delay time between the original
signal and the chorused signal. The higher the
setting, the longer the delay and the wider the
chorusing effect. Delay is adjustable from 0–20
milliseconds.
LFO Rate Adjusts the rate of the LFO (low fre-
quency oscillator) applied to the delayed signal
as modulation. The higher the setting, the more
rapid the modulation. You can select either a
sine wave or a triangle wave as a modulation
source, using the LFO Waveform selector.
LFO Width Adjusts the intensity of the LFO ap-
plied to the delayed signal as modulation. The
higher the setting, the more intense the modu-
lation. Use the LFO Waveform selector to select
a sine or a triangle wave as a modulation source.
Feedback Controls the amount of feedback ap-
plied from the output of the delayed signal back
into its input. Negative settings provide a more
intense effect.
LFO Waveform Selects a sine wave or triangle
wave for the LFO. This affects the character of
the modulation. The sine wave has a gentler
ramp and peak than the triangle wave.
