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 ...
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.
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.
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 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 .
MXR also had a line of professional rackmount effects used by the likes of David Gilmour, [6] Stuart Adamson and Mike Rutherford. The first product introduced was the Digital Delay, which had delay times from 0.08ms to 320ms, but users could purchase additional plug-in memory boards that were user-installable and could increase delay times to ...
In spite of the name, most electronic chorus effects do not accurately emulate the acoustic ensemble effect. Instead, they create a constantly moving electronic shimmer. Some pitch shift pedals create a slightly detuned unison effect which is more similar to the acoustic chorus sound.
Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano). Pitch correction devices do this without affecting other aspects of its sound.
