Auto Tune

So a while ago someone took a live Beyonce performance and "tweaked" it in autotune to make it sound completely out of tune, to the extent that it's blatantly obvious to everyone who hears it. Or at least, everyone except for Howard Stern, who took it at face value and played it nationally across the states. Take a listen.. obviously been messed about with but it goes to show how much you can do with a vocoder..
