AriVibes allows you to perform realtime manipulatations over sound picked up by your iPhone, iPod, or iPad's microphone.
AriVibes can record and repeat the sounds you send into it, allowing you to easily build musical phrases and compositions.
AriVibes can make objects sound more percussive. Your tap on a table can have the bass of a kick drum or the brilliance of a hi-hat.
AriVibes can record your session into an audio file that you can export via iTunes.
