variabelpitch

Variabelpitch refers to a technology primarily found in audio playback devices and software that allows for the alteration of the speed at which an audio signal is reproduced, consequently affecting its pitch. This is distinct from technologies that only alter speed without changing pitch, or those that only alter pitch without changing speed. When pitch is varied, the duration of the audio is also affected. For example, playing an audio file faster will result in a higher pitch and a shorter duration. Conversely, playing it slower will result in a lower pitch and a longer duration. This functionality is commonly found in music production software, DJ equipment, and some digital audio players. It enables creative manipulation of sound, such as creating sound effects, adjusting tempos for musical performance, or correcting minor timing errors in recordings. The underlying algorithms for variabelpitch processing aim to maintain a natural sound quality while allowing for significant deviations from the original playback speed and pitch. Early implementations might have produced noticeable artifacts, but modern algorithms have greatly improved the fidelity of variabelpitch adjustments.
