Voloco

Voloco is a voice-processing app that combines automatic tuning, pitch-shifting, and vocoding. Voloco can be used in real-time with headphones. Without headphones, Voloco can still record and playback processed vocals.

Voloco's automatic tuning algorithm can tune output to the user's choice of six scale types in any key. Voloco currently supports recording segments of audio up to six minutes in length and stores them as mono 22050 hz WAV files on the user's SD card.

TIPS

* Keep the mic close to your mouth and at an angle so that your breath does not directly hit it.
* Using external speakers will probably result in reverberation effects that can be rather fun.

Thanks for trying Voloco! If there's a problem, please file a bug report.
