is a time delay effect in which the dry signal is mixed with a briefly
delayed version of itself.
If this short delay is in the region of 0 - 20 milliseconds the ear
will not be able to resolve the two signals separately but will hear them
as one signal with phase
|The flanging effect is made most noticable when the delay
time is modulated by a low
frequency oscillator (LFO).
This has the effect of causing the frequencies of the phase cancellations
and accentuations to shift up and down the frequency spectrum providing
the characteristic "swishing" effect.
Flanging is aurally very similar to phasing
which creates a similar effect through the use of phase-shift circuitry.
