音高移位/Yin1 Gao1 Yi2 Wei4
The application of a function to alter the pitches of sounds, most commonly changing their duration as well. Pitch-shifting without this side-effect is related to time-stretching. In some machines this function can be controlled by oscillators, by hand-drawing or even by dynamic envelopes extracted from the sound itself or from other sounds. The expression designates only the effect on pitched sounds, but such a process can also be applied to non-periodic, non-pitched sounds or whole events. (Source - Rodolfo Caesar (1992).

This refers to the changing of the Pitch in either direction. Traditionally pitch shifting went hand in hand with the change of speed of a tape recorder.
With today’s digital technology, pitch shifting can take place alongside time stretching and compression whereby the duration need not be altered, only the pitch. Plunderphonics Plunderphonic composition is a specific, radical form of collage in which all materials have been appropriated from existent music. It is a politically motivated genre that is focused on the notion of free samples and challenging perceived hypocrisy of musical copyright law. The term is derived from the seminal CD by John Oswald called ‘Plunderphonics’. [EARS]
