Flanger

A flanger is an audio effect that creates a swirling, sweeping sound by blending a signal with a slightly delayed version of itself. This delay is continuously varied, causing the sound waves to interfere with each other, producing characteristic whooshing and pulsating effects. Think of it as a shimmering or jet plane-like tone. Flangers are used in music and sound design to add depth, movement, or a futuristic quality to sounds. The effect is achieved through effects pedals or software, controlling parameters like the delay time and feedback to shape the desired sound.
