Пакет: autotalent (0.2-5)

pitch correction LADSPA plugin

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 or played on some kind of instrument. As long as you give it a monophonic source (i.e. a melody in a single, 1-channel track), you can usually expect 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.
