Flanging was originally created in the sixties, by playing two reel to reel tape decks, both with the same sound on them, at the same time, and slowing one down by pressing a finger on the tape flange. This creates the popular jet sound heard in movies and music.

Flangers are time delay effects, similar to the chorus effect, but they normally have a shorter delay time. One or two (for stereo) modulated delay signals are combined with the original, unaltered, signal to create this effect. Because the flanger effect is a modulated delay effect, the delay changes over time. For example, the delay could sweep from 0ms to 4ms or 1ms to 12ms repeatedly.
Flangers are usually modulated by triangle wave LFOs, because they create a constant, periodic, sweeping sound that doesn’t speed up or slow down at different parts of the sound file. The MXR flanger is modulated with a sine wave. This causes the flanger to speed up and slow down at different places in the sound file.
