Auto-Tune

Auto-Tune is a proprietary audio 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 has allowed many artists to produce more precisely tuned recordings.

Auto-Tune is available as a plug-in for professional audio multi-tracking suites used in a studio setting and as a stand-alone, rackmount unit for live performance processing.
