Phasers make synths sway

Transcript

A phaser splits the sound, shifts one path with all-pass filters, then mixes it back with the dry signal, so peaks and notches appear and move across the spectrum. The rate control sets how fast the sweep moves, while feedback feeds some output back in to make the notches deeper and more resonant. On a pad, dry audio sounds still and plain, but phased audio adds that watery, swooshing motion that producers use for guitars, vocals, synths, and ambient textures. Quick checklist: classic house, use a slow rate, moderate depth, and enough feedback for a lush sweep; modern ambient, go slower, widen the stereo feel, and keep the motion subtle.
