I'm not familiar with the app, but in sound production, autotune is a recording software plug-in that will alter a sung vocal note to the closest tone in a given scale. When used correctly it can cover singing mistakes almost imperceptibly. When used with a heavy hand it "forces" the pitch change and sounds robotic. The Black-Eyed Peas used the latter effect in "Boom, Boom, Boom" if that gives you a point of reference.
Thank you. I had no idea what we were talking about.correct. "i am t-pain" is a voice transformer. it automatically tunes your voice so that it is on key. i remember looking for a similar app when i first got my droid but could not find one or atleast one that had a good review for it. i would def. look at the apps reviews before taking the plunge because in most cases you can tell if the app is worthy of downloading it or not just by seeing what people had to say about it.
