It got even more exposure to the masses when an iPhone app hit the Apple App Store courtesy of music artist T-Pain and master music app developers Smule. MicDroid for Android is a work in progress and it isn't as snazzy as the iPhone's I Am T-Pain app, but it'll get the job done with pre-recorded sound samples.
Just put your mouth up to the mic, record yourself singing something, then use the supplied options to pitch and tone correct to your satisfaction. You're just a few touchscreen taps away from potentially joining the ranks of today's YouTube viral video makers.
Jay-Z tried to say a year ago that Auto-Tune was D.O.A. but given the release of MicDroid and the popularity of I Am T-Pain, Auto-Tune fans of the world can go on and brush that dirt off their shoulders.
