Flanging is a technique used in music production to create a unique sound effect. However, there are various synonyms for flanging that can be used to describe similar effects. For example, phasing is a technique that involves altering the phase of one part of a stereo signal to create a sweeping sound. Chorus is another technique that creates a similar effect to flanging by duplicating the original signal and delaying one of them slightly. Comb filtering is also used to create similar sweeping effects by filtering certain frequencies of a signal. Additionally, some producers opt for using reverb, delay, or echo effects to achieve similar results to flanging.
