autotalent 0.2-3 (ppc64el binary) in ubuntu trusty

 Autotalent is a real-time pitch correction plugin. Users can specify
 the notes that a singer is allowed to hit, and Autotalent makes sure
 that they do. Autotalent may be used for more exotic effects, like
 the Cher / T-Pain effect, 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.
 .
 Autotalent was designed from the ground up to process musical melodies,
 whether sung by voice or played on some kind of instrument. As long as
 one gives it a monophonic source (i.e. a melody in a single, 1-channel
 track), he can usually expects pretty good results. So this means that
 if you're in the business of processing vocal harmonies, you should
 apply it to each monophonic vocal part separately. If in the spirit of
 experimentation you're daring enough to try tuning or pitch shifting
 an entire chord using one instance of the plugin (again not what it's
 meant for), you'll hear gritty nastiness.
