Flanging

Flanging is an audio effect created by mixing a sound signal with a slightly delayed version of itself, then continuously changing that delay. This causes the sound to shift in tone, creating a characteristic sweeping, whooshing sensation. It resembles a swirling or jet-like sound and is often used in music and sound design to add movement and texture. The effect depends on the precise timing of the delay and modulation, producing a vibrato-like pulsating sound that enriches the original audio.
