Pitch shifters are included in most audio processors today. A harmonizer is a type of pitch shifter that combines the pitch-shifted signal with the original to create a two or more note harmony. The Eventide H910 Harmonizer, [2] released in 1975, was one of the first commercially available pitch-shifters and digital multi-effects units. On ...
The computer algorithm allows frequency-domain modifications to a digital sound file (typically time expansion/compression and pitch shifting). At the heart of the phase vocoder is the short-time Fourier transform (STFT), typically coded using fast Fourier transforms .
Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed simultaneously by slowing down or speeding up a recording.
A pitch shifter (also called an "octaver" for effects that shift pitch by an octave) raises or lowers (e.g. "transposes") each note a performer plays by a pre-set interval. For example, a pitch shifter set to increase the pitch by a fourth will raise each note four diatonic intervals above the notes actually
The DigiTech Whammy is a pitch shifter pedal manufactured by DigiTech.It raises or lowers the pitch of an audio signal by up to two octaves, controlled with a treadle.The first model, released in 1989, was the first mass-market digital pitch shifter.

Mathur was offered a full-time job as a technology consultant at the global consultancy Protiviti before even graduating. “I was in my 20s advising much more senior people on all things tech at ...
The processor slightly shifts pitches to the nearest true, correct semitone (to the exact pitch of the nearest note in traditional equal temperament). Auto-Tune can also be used as an effect to distort the human voice when pitch is raised or lowered significantly, [9] such that the voice is heard to leap from note to note stepwise, like a ...
