Flanger<br />
A flanger is a very short delay line whose output is mixed back together with the original<br />
sound. Mixing the original and delayed signals results in multiple frequency cancellations<br />
known as a comb filter. Since the flanger is a type of filter, it works best with<br />
harmonically rich sounds.<br />
A low frequency oscillator is included to slowly change the delay time. This creates a<br />
rich, sweeping effect as the notches move up and down across the frequency range. The<br />
amount of feedback deepens the notches, intensifying the effect. You can invert the<br />
feedback signal by choosing a negative feedback value. Inverting the feedback signal<br />
creates peaks in the notch filter and deepens the effect.<br />

Parameter Description<br />
Phase<br />
Out<br />
Delay Sets the initial delay of the flanger from 0-4 mS in 1/100th millisecond<br />
increments. This parameter allows you to “tune” the<br />
flanger to a specific frequency range.<br />
Feedback Controls how much signal is recirculated through the delay line<br />
and increases resonance. Negative values can produce intense<br />
flanging with some signals.<br />
LFO Rate Sets the frequency of the low frequency oscillator.<br />
LFO Depth Sets how much the LFO affects the delay time. Increases the<br />
animation and amount of the flanging effect.<br />
LFO Waveform Selectable between Sine or Triangle wave.<br />
LFO L/R Phase Controls the stereo width by adjusting the phase difference<br />
between the left and right sweeps.<br />
