Yeah, out of time and tune? Eek… Seriously, though, I’ve found Vari-Audio and Quantize in Cubase to work fairly well. Depending on what you’re going for, you could edit the audio from there. However, again depending on your project, correcting for time and tuning may be a good way to show a vocalist a) where they are having trouble, and b) provide a “perfected” take to practice to. It is interesting that even good singers, when singing original material, can’t nail it until they “know” the melody.
