Globetechnology | Delivering perfect pitch:
[T]he music industry is divided over the use of computer hardware called autotuners, used by acts such as Britney Spears and N Sync ... Pop stars and punk bands alike are piping their voices through the hardware, which corrects and improves their vocal pitch during concerts and on records. Well, they are called NSync, not NTune. I think it's cheating, at least on stage. In the studio it's a different matter; it's more like being lazy (or having to put down a track in too short a time).
