The Flanger Effect.
Flanger uses two parallel time-modulated delays to create anging effects.
Flanger's delays can be adjusted with the Delay Time control. The Feedback control sends
part of the output signal back through the device input, while the Polarity switch (+ or
-) sets the polarity. Delay Time and Feedback can be changed simultaneously using the
effect's X-Y controller.
Periodic control of delay time is possible using the envelope section. You can increase or
decrease the envelope amount (or invert its shape with negative values), and then use the
Attack and Release controls to dene envelope shape.
Flanger contains two LFOs to modulate delay time for the left and right stereo channels.
LFOs can have six possible waveform shapes: sine, square, triangle, sawtooth up, sawtooth
down and random. The extent of LFO inuence on the delays is set with the Amount control.
Flanger's LFO speed is controlled with the Rate control, which can be set in terms of hertz.
