Working out this morning I had the realization that every band on the radio (i forgot my headphones) was using Auto-Tune.
... It is used to disguise off-key inaccuracies and mistakes, and has allowed singers to perform perfectly tuned vocal tracks without the need of singing in tune. While its main purpose is to slightly bend sung pitches to the nearest true semitone (to the exact pitch of the nearest tone in traditional equal temperament), Auto-Tune can be used as an effect to distort the human voice when pitch is raised/lowered significantly...
Sounds a lot like what PhotoShop has been for photographers for a while now. You cannot publish a photograph any more with out extensive photoshoping. And now you too can act like a pro with iphone apps like: Tilt Shift Generator, Camera Bag, or even iTimelapse Pro. wow.
So, without further delay, please enjoy below the master of Auto-Tune, T Pain, using his hugely successful iphone auto-tune app to riff on Obama.
