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 from 0-4 mS in 1/100th milli-

second increments. This parameter allows you to “tune” the

ﬂanger to a speciﬁc frequency range.

Feedback Controls how much signal is recirculated through the delay line

and increases resonance. Negative values can produce intense

ﬂanging with some signals.

LFO Rate Sets the frequency of the low frequency oscillator.

LFO Depth Sets how much the LFO affects the delay time. Increases the

animation and amount of the ﬂanging effect.

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.
