** In your signature, John, it says something about "professional sound
reinforcement" - well that is the area of technology I work in.
If you have ever seen a working PA or SR system there in the FX rack
you will find a digital effects processor, possibly made by Yamaha, Roland,
Lexicon, TC Electronics et alia.
They all have a pitch shift function but never a frequency shift one.
Similarly I doubt there is a studio anywhere, small or large, that
does not have the same or similar units available. There are even battery
operated "pedals" that do it for guitarists.
