Formant shifting is the "secret sauce" for modern vocal production. Unlike basic pitch shifting, which just moves the note up or down (the "chipmunk effect"), formant shifting mimics changing the physical size of a singer’s vocal tract. Lowering the formant makes a voice sound "deeper" or more masculine without changing the melody, while raising it creates a "brighter" or more feminine character.
