Antares Auto-Tune 3 Pitch Correction Software

Engineers can banter back and forth for eons about the good vs. evil scenarios involving pitch-corrected vocals. The bottom line? If you know what you're doing (and believe me it takes a lot of practice), pitch correction can both save an injured vocal and be totally undetectable. There are lots of examples on the radio of obvious pitch correction, so it gets a bad rap. What you aren't hearing are the other songs that use it so well you don't know it's there. All engineers have to record sucky vocalists from time to time. Where do you spend your energy? This little plugin can save your ass!
