Voice Candy 1.1 has just been released, and it brings voice memo management to this very clever little voice altering program. We blogged about it when it was first released, and it looks like it has just gotten better with this .1 release. Also added in this free update is the ability to listen to the voice effects as they are applied in real time (though you shouldn't use the internal mic and speakers to do this. Can you say feedback?).
Voice Candy is $12.95 and there is a 15 day demo available.
