MicDroid is a small Android app that produces the pitch correction effect made famous by T-Pain. 

 It's based on the AutoTalent pitch-correcting LADSPA plugin, by Tom Baran, with more information available from his personal site here.

The app is available under the name 'MicDroid' in the Android Marketplace, and the source is available from github.

License information for MicDroid can be found on github as well.
