Flanging was first done with two tape machines playing the same recording, while an engineer pressed a finger on the rim of one reel (the flange) to slow it. The two copies drift in and out of step and a sweep moves through the sound.

Here you set how fast the sweep moves, how deep it goes and how much resonance it has. High resonance gives the metallic, hollow tone.

How to use the Flanger Effect tool

  1. Add your audio file.
  2. Set the sweep speed, depth and resonance.
  3. Apply the flanger and download the swept version.
  • Psychedelic guitar and drum fills
  • A sweep across a whole section of a track
  • Sci-fi sound design

Tips for the best result

  • A slow sweep (under 0.5 Hz) sounds musical. A fast one sounds like a wobble.
  • Sounds with lots of high frequencies, like cymbals and distorted guitar, show the effect most.

Frequently asked questions

Can I flange only a few bars?

Trim those bars out, apply the effect, and join the pieces again with the Audio Joiner.

Why is the effect subtle on my voice recording?

Speech has little high-frequency content for the sweep to work on. Raise the depth and resonance.

Does it work in stereo?

Yes. Left and right are swept slightly out of step, which adds width.

Is the result louder?

Resonance can raise the level, so a limiter keeps it from clipping.
