Flanging is an audio effect created by mixing a signal with a slightly delayed copy of itself, then slowly varying that delay over time. This produces a characteristic swooshing, jet-plane, or “whooshing” sound. How it works- Two nearly identical signals are combined.- One is delayed by a very short time, usually just a few milliseconds.- The delay is modulated, often with an LFO.- The two signals interfere with each other, causing comb filtering: - some frequencies get boosted - others get cancelled- As the delay changes, the notches in the frequency response move, creating the sweeping effect. Typical controls- Delay time: very short, often 0.1–10 ms- Depth: how much the delay varies- Rate: speed of modulation- Feedback: feeds part of the output back in for a more intense effect- Mix: balance between dry and effected signal Sound examples- Jet flyby / sweeping metallic effect- Thickening and movement on guitars, vocals, drums, synths Difference from chorus- Flanging uses shorter delay times and stronger comb filtering- Chorus uses slightly longer delays and aims for a thicker, less metallic soundIf you want, I can also explain:1. how to make flanging in a DAW, or 2. the difference between flanging and phasing.
