"Phasing" redirects here. For the compositional technique in which a repetitive phrase is played on two musical instruments in steady but not identical tempo, see Phasing (music).

A phaser is an electronic sound processor used to filter a signal by creating a series of peaks and troughs in the frequency spectrum. The position of the peaks and troughs is typically modulated so that they vary over time, creating a sweeping effect. For this purpose, phasers usually include a low-frequency oscillator.
