Creates a sweeping, whooshing filter effect with a metallic, ringing sound.
Flanger applies a modulated whooshing sound (resulting from phase reinforcement and cancellation) to the input signal. A comb filter, frequency modulated by a sine wave, is used to create this effect. You can specify the range of frequencies over which the filter sweeps, and how fast the filter sweeps up and down. The amount of resonance can be controlled, and the mix ratio of the input signal to the effected signal can be adjusted (wet/dry mix).
See the Adjusting Contraption Properties section for information about using sliders, knobs, presets etc.
Specifies the minimum and maximum frequencies that the filter sweeps between, ranging from 20 Hz - 4000 Hz.
Specifies how fast the filter is swept up and down in pitch between the minimum and maximum frequencies, specified by Range. The rate ranges from 1 cycle every 100 seconds to 100 cycles per second.
Controls the amount of feedback. Higher values of feedback cause the flanger to ring or resonate producing a more noticeably pitched effect.
Controls the ratio of input vs. flanged signal.

The flanger effect was originally produced by using two slightly out of sync reel-to-reel tape machines playing the same sound. By leaning on the flange of one of the tape reels, the speed of one of the tape decks could be slightly altered, resulting in subtle phase cancellations between the sounds played from the two tape machines. This contraption is a digital implementation of a flanger.
