Hi Gambler,

There are some standalone programs that will try to do this sort of conversion and several of the big Digital Audio Workstation pieces of software have some limited capabilities. The technology will get there someday but it isn't anywhere near yet as far as I can tell.

This video explains it better than I ever could and is well worth a watch:

My son is doing Music Technology in college and he's telling me that there are tools used by major studios to do it but they still require editing. No doubt it will filter down to us but it seems that it's a few years away.

Best wishes,
Mike
