AUTOTUNE
Auto-Tune
Auto-Tune is an audio processor created by Antares Audio Technologies, which uses a proprietary device to measure and alter pitch in vocal and instrumental music recording and performances through use of a phase vocoder. It was originally intended to disguise or correct off-key inaccuracies, allowing vocal tracks to be perfectly tuned despite originally being slightly off-key.The above text is a snippet from Wikipedia: Auto-Tune
