Yes, this is pitch shifting ...When you change the speed, the pitch
implicitly changes (eg. a double of speed will cause a one octave shift)
...So after you have changed the speed, say "up", you then need to change
the pitch back "down" ...hope that makes sense.

When you examine their code, you will find the details on how this is
implemented. It's not that difficult to port it over to Rockbox.
