Antares Auto-Tune RTAS PC

Auto-Tune provides two different approaches to pitch correction.
For most common pitch problems (and correcting live performances in real time), Auto-Tune Automatic Mode instantaneously detects the pitch of the input, identifies the closest pitch in a user-specified scale (including minor, major, chromatic and 26 historical and microtonal scales), and corrects the input pitch to match the scale pitch.
