If you have tuning issues or want that ‘Auto-tune’ effect then there are a couple of obvious contenders, the most obvious being the daddy of them all, Auto-Tune Pro. It’s managed to stay ahead of the rest by heaping in some wonderful and easy to implement features, over and above that classic vocal effect and has almost become the ‘Hoover’ of plugins along the way. That said, if you want the quick, down and dirty version then Soundtoys’ Little AlterBoy impresses us with its simplistic but beautiful approach to not only Auto-Tune style effects, but brilliant male to female and female to male formant editing and more.
