Facility on some sound playback devices for changing the speed of playback, and thus the pitch or frequency of the sound, to match an existing sound, or to fit a particular timeslot. Some Professional CD players have tempo controls which speed up the playback, and then compensate for the resulting increase in frequency using a pitch change. This results in the ability to match the beat of a CD in a disco situation, without the "Pinky and Perky" effect.

A method of controlling a wind turbine's speed by varying the orientation, or pitch, of the blades, and thereby altering its aerodynamics and efficiency.

Is useful for practicing with musical instruments, dancing and language lessens. DJs will also love this feature. You can control the pitch by the chromatic semitone or by dB with 0.1% pitch. The total range of the pitch control is +2 semitone to -48 semitone for normal PITCH mode or +12.5% to -98.5% for fine pitch F.PITCH mode. This is made possible by continuously sampling the data at 44.1khz and changing the interval of data pickup. The disc rotation speed is not changed.
This allows you to adjust the speed of the platter/ record, if necessary.
A few CD and CD-R/RW decks let you increase or decrease the playback speed in precise increments — a great feature for DJs, musicians, and aerobics enthusiasts.
Allows you to increase or decrease the speed of playback in order to raise or lower the music's pitch.
This pitch control permits the user to vary the tape speed in playback. By changing the tape speed, the pitch (frequency) of the recorded sound can be changed when playing back tapes.
A variable speed pitch control (or vari-speed) is a control on an audio device such as a turntable, reel-to-reel, tape deck or CD player that allows the operator to deviate from a standard speed (such as 33â…“ or 45 rpm in the case of a turntable). The latter term "vari-speed" is more commonly used for tape decks, particularly in the UK. Analog pitch controls vary the voltage being used by the playback device; digital controls use digital signal processing to change the playback speed or pitch.
