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.

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°
