Flanger
The Flanger animates and adds a swirling, mov-
ing quality to audio material by combing a time-
delayed copy of an audio signal with itself.
The Flanger uses a through-zero flanging algo-
rithm that results in a tape-like flanging effect.
This technique delays the original dry signal by
256 samples, then modulates the delayed signal
back and forth in time in relation to the dry sig-
nal, passing through its zero point on the way.
Gain
Adjusts the input volume of the flanger 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 and 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 phase in-
verted to enhance the mono-stereo 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%.
High-Pass Filter Controls the cutoff frequency of
the High-Pass Filter. Use this to attenuate the
frequency content of the feedback signal and
the frequency response of the flanging. The
higher the setting, the more low frequencies are
removed from the feedback signal.
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.
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.
The Flanger plug-in was formerly called
D-fx Flanger. It is fully compatible with all
settings and presets created for D-fx
Flanger.
