Melodyne is in a tight battle with Autotune for control of the vocal editing industry. But between the two, I’d have to give them my recommendation. Melodyne allows you to fix the tuning of your vocals in a natural way, allowing you to focus on emotion and excitement in your recording sessions rather than pitch.
Melodyne Editor is the most popular version, but if you’re okay with only being able to tune monophonic sources (that means no chords), then Melodyne Assistant is a great, cheaper option.
