Hi Tony.
I don't mean to be rude, but you really are not up to speed on all this. I've had singers in my Studio who should have been shot and put out of their misery, yet they leave the Studio sounding amazing.

For years I've been using pitch correction, adding Vibrato, Breath, Growl, Rasp and many other aspects of Voice Modelling Technology to singers voices. I even have Gender Change technology by where a guy can sing and do female harmony to his own songs.

The only thing this video demonstrates is just how little people are aware of what has been on the market for the last 10 years.

I'm really shocked by that...!!!!

Regards
James.
