Vocal Pitch & Formant Shifter · macOS AU / VST3

Drag any vocal down to the abyss.

A phase-vocoder pitch and formant shifter that moves pitch and vocal-tract character independently — so an octave-down vocal stays loud, crisp and cutting, never a chipmunk or a muddy blur.

The signature

Pitch and formant, moved apart.

The phase-vocoder engine shifts pitch and vocal-tract character independently, with cepstral formant tracking and transient preservation so consonants stay crisp. Push both down and you get a demon, not a chipmunk or a mud-covered growl.

One control, one octave down — the ABYSS move.
