Pitch shifter
A pitch shifter is an audio processor that changes the pitch of an audio signal. Originally marketed by Eventide as the Harmonizer effects processor, advances in digital signal processors soon made higher-quality pitch shifting and harmonic pitch shifting possible.
Since the mid-1990s, formant correction has been available to avoid the "chipmunk voice" effect that typically occurs when shifting vocal pitch upwards. Pitch shifters are included in most multi-effect generators today.
