Autotalent is a real-time pitch correction plugin. You specify the notes that a
singer is allowed to hit, and Autotalent makes sure that they do. You can also
use Autotalent for more exotic effects, making your voice sound like a
chiptune, adding artificial vibrato, or messing with your formants. Autotalent
can also be used as a harmonizer that knows how to sing in the scale with you.
Or, you can use Autotalent to change the scale of a melody between major and
minor or to change the musical mode.
