They also make a free (and very good) ready-to-use pitch shift
AudioUnit called "DiracFxAU" that comes with full project source code,
you might want to check that out. It's part of their DiracLE package:
http://dirac.dspdimension.com
If you don't want to use their DiracFx API I bet you can plug their
public domain code into that AU and use that. There is an active forum
at http://www.surroundsfx.com/forum/viewforum.php?f=18 that has been
very helpful to me when I wanted to do the same thing a few years
back.
Their tutorial code isn't optimized and they don't recommend it for
use in actual products. There are several popular libraries that use
it nonetheless such as FMOD, so I bet with a little extra work you
should be able to get it to work for you as well.
Hope this helps!
