Our engine cascades all-pass filters from 2 to 12 stages, creating frequency notches that sweep back and forth to yield the distinct phaser swoosh.
Get started quickly with five classic presets, ranging from a subtle shimmer to deep space orbits and fast jet sweeps.
Watch the LFO sweep speed, depth, feedback, and active filter stages represented visually on our orbiting circular dial scope.

Frequently Asked Questions
An audio phaser splits an audio signal into two paths. One path is left unaltered, while the other is passed through a series of all-pass filters that shift its phase. When recombined, the phase-canceled frequencies create notches, and modulating these notches with an LFO creates the sweeping effect.
Rate changes LFO speed; Depth adjusts LFO sweep range width; Feedback feeds a portion of the output back to the input to intensify the sweeps; Mix blends the original (dry) and phase-shifted (wet) signals.
More stages mean more frequency notches and a more complex, swooshing sound. 2 stages sound like a subtle vibe; 4 stages offer classic vintage chorusing; 8 to 12 stages produce deep, rich swooshes.
