Park Road Post used it to clean up the sound in the Beatles Get Back videos. I don't know the details, and I haven't seen the original or Get Back, but apparently the sound in the original was terrible. They used 'AI' to do things like pick out George's (or whoever it was) voice from the rest so they could EQ it separately
