Auto-Tune Evo (formerly Auto-Tune) is a multi-platform plug-in that corrects intonation problems in vocals or solo instruments, in real time, without distortion or artifacts, while preserving all of the expressive nuance of the original performance with audio quality so pristine that the only difference between what goes in and what comes out is the intonation. Over a typical pitch correction range, it is simply not possible to tell that a sound has been processed, except that it is perfectly in tune.

Automatic Mode
Most common pitch problems can be corrected by Auto-Tune 4's Automatic Mode. 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. A Retune Speed control lets you match the retune rate to virtually any performance style.

Graphical Mode
For meticulous tweaking, the Graphical Mode displays the performance's detected pitch envelope and allows you to draw in the desired pitch using a variety of graphics tools. This mode gives complete control over the correction or modification of the most elaborate expressive gestures.
