Flanger
A flanger is a very short delay line whose output is mixed back together with the original
sound. Mixing the original and delayed signals results in multiple frequency cancella-
tions known as a comb filter. Since the flanger is a type of filter, it works best with
harmonically rich sounds.
A low frequency oscillator is included to slowly change the delay time. This creates a
rich, sweeping effect as the notches move up and down across the frequency range. The
amount of feedback deepens the notches, intensifying the effect. You can invert the
feedback signal by choosing a negative feedback value. Inverting the feedback signal
creates peaks in the notch filter and deepens the effect.
Parameter
Description
Delay
Sets the initial delay of the flanger in .01 millisecond increments. This
parameter allows you to “tune” the flanger to a specific frequency
range. Range: .01ms to 4ms
Feedback
Controls how much signal is recirculated through the delay line and
increases resonance. Negative values can produce intense flanging
with some signals. Range 0% to 100%
LFO Rate
Sets the speed of the flanger sweep. Range: .01 Hz to 10Hz
LFO Depth
Sets how much the LFO affects the delay time. Increases the animation
and amount of the flanging effect. Range 05 to 100%
LFO Waveform
Selectable between Sine or Triangle wave.
LFO L/R Phase
Controls the stereo width by adjusting the phase difference between
the left and right sweeps. Range: -180° to +180°
