Auto-Tune is a proprietary auio processor created by Antares Audio Technologies which uses a phase vocoder to correct pitch in vocal and instrumental performances. It is used to disguise inaccuracies and mistakes, and – due to its increasing use in modern music – has allowed many artists to produce more precisely tuned recordings. While Auto-Tune is only one out of many commercial pitch correction packages, auto-tune is frequently used in the media as a blanket term to describe any audio processing with a similar effect, perhaps because it was the first product allowing pitch correction in real time.
