Flanger
The "flanger" effect is similar to the chorus, but its history is different. It was developed by coincidence
when someone (according to legend it was actually John Lennon!) briefly slowed down one of the reels
of two tape machines that were linked together.
The result: the rather brief delay of the second signal compared to the first resulted in cancellations within
the frequency spectrum, leading to a so-called comb filter effect (the sum of both signals creates "peaks"
and "lows" in the spectrum that look familiar to the teeth of a comb).
Flanging is basically a chorus effect that modulates a shorter delay time (under 10 ms). Flangers are not
meant to double or disembody a sound like chorus does, but aim to manipulate its frequency range.
When the "Feedback" parameter is turned up, a familiar flanging effect is produced – the sound
characteristics of a jet engine warming up.
Flanger parameters
Speed
: Modulation speed.
Depth
: The overall amount of modulation.
Feedback
: The volume of the internal feedback loop.
Mode:
Normal
: Flanging.
Dual
: Two parts, panned left and right.
Quad
: Four parts, alternately panned left and right.
Quad pan
: Like "Quad", but the "Depth" control also sets the intensity of the signal's pan movements between left
and right.
