How can i make a microphone work live?

I don't know if this is what you're looking for. But this video shows you how to "Auto-tune" your voice (FOR FREE). Check out the Youtube video here a href="http://www.youtube.com/watch?v=mpEPFc_1ibA&list=PL996F2FA9DD114106." rel="nofollow"http://www.youtube.com/watch?v=mpEPFc_1i…/a
