There are utilities that can do pitch shifting for you, but how much do you want to alter the key? If you try to do more than, say, two half-steps, the quality of the base song will suffer. And, certain instruments stand up better than others. I have never been able to pitch-shift an acoustic guitar well, for example.

Of course, I have to say that I have not used any audio editor with the Elastique algorithm BIAB now uses. Maybe things have changed.
