Formant shifting changes these peaks independently of pitch, making a voice sound:
Type: Experimental Formant/Resonance Filter Format: VST (Windows only)
This one is for the sound designers. ROXX isn't a typical "clean" formant shifter. It is a distortion box that uses formant filters (vowel filters: A, E, I, O, U) that can be shifted dynamically.
When to use it: If you want to turn a snare drum into a talking drum, or a vocal into a Dalek from Doctor Who. It handles "extreme" formant shifting much better than clean plugins because it embraces the digital grit.

In the world of sound design and vocal production, few effects offer the "alien vs. giant" magic trick quite like a formant shifter.
While standard pitch shifting changes the note of a sound (making Chipmunks or Monsters), formant shifting changes the character of the resonator—essentially altering the size of the throat, mouth, or soundbox without changing the musical pitch.
