Waves tune real time.

New Waves tuning plugin for live and recording vocals.

I think we've all possibly sung at times and been out of tune. Be it that you're tired or can't hear what you're singing, Waves have developed a new plugin that actually tunes the notes of your choice in real time and not that awful Auto tune sound but natural vocal tuning. I guess it would save expensive Studio time for vocalists that don't have good pitching. Check out the video near the end.
