Pitch control

Pitch Control (English pitch control, pitch adjustment) is a function in reproducing apparatus to active primarily to control the pitch or the velocity and to keep for a certain period. Record players, tape machine, music software, synthesizer, as well as sampler etc. offer this function.

With turntables and tape machines, the rotational speed of the platter or the sound wave is increased or decreased by the pitch control. As a (usually undesirable ) side effect is the change in velocity. A DJ uses the function to synchronize the music of two different records tempo-wise. To change the tempo without affecting the pitch, there is the possibility of temporal extension, see time-stretching. But this feature is turntables and tape recorders are not available.

Software media player need no pitch control normally. Some computer jockeys who handle digital audio files on the PC, use the function analogous to the turntable.

For audio editing programs usually a permanent change in pitch (English pitch shift) is made. Even with the setting in the video section will pitch control application. To only change the tempo but is usually carried out a temporal extension.

With synthesizers and samplers is with the pitch control ( also called pitch shift or transpose ) the possibility to transpose the notes on a keyboard up or down. Are usual shifts to half steps. To tune or out of tune notes fine then used to fine-tune (English fine- tune). For samplers pulling up or scaling down the pitch of a voice recording to 12 semitones or more used to be, either to create a Mickey Mouse voice or a devil voice, the pitch regulation here is not absolutely necessary because the keyboard itself the samples per higher or lower after key plays and thus enters the effect no later than one octave of itself. Here at the Mickey Mouse voice, the voice is not only higher, but also faster. Conversely, in the devil 's voice, which will also slow down then. The speed can then correct again with time stretch.

The pitch control ( English pitch control ) is not to be confused with the pitch bend, where you typically continually bends the sounds and generally does not hold in a certain pitch.
