"Autotune" has become a colloquial term for pitch correction software. Originally a trademark of Antares Audio Technologies, it now refers to a category of software that automatically detects the pitch of a vocal performance and corrects it to the nearest semitone. While professional industry standards (Antares Auto-Tune, Melodyne) can be expensive, several high-quality free alternatives exist.
