Core Effects Descriptions

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 1/100th millisecond incre-
	ments. 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 0% 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°
