What is Auto-Tune?

Auto-Tune is a pitch correction software developed by Antares Audio Technologies that is used to adjust the pitch of recorded vocals or instruments. It works by detecting the pitch of an audio signal and automatically shifting it to the nearest correct musical note based on a selected key or scale.

Auto-Tune can be used in different ways depending on how its settings are adjusted. When used subtly, it corrects small tuning imperfections in a vocal performance while preserving a natural sound. When the retune speed is set very fast, it creates a distinctive robotic or synthetic vocal effect that instantly snaps notes to pitch.

Since its introduction in the late 1990s, Auto-Tune has become widely used in modern music production. It is commonly applied to vocals in pop, hip-hop, and electronic music, both as a tool for improving pitch accuracy and as a recognizable creative effect.
