Re-pitching PAL to correct 4% speedup

Can anybody advise on the best method to correct the pitch on PAL film sourced 25fps audio to adjust for PAL speedup? I'm informed it's around half a semitone.

Can it be accomplished with the AUPitch filter? Or would it be best to use Soundtrack?

My settings would do you no good. I wasn't converting from NTSC to PAL. I was fitting a 1 hr, 3 min video into a 1 hr time slot, and I only had to adjust the pitch to make sure the speaker didn't sound like a Teletubby. If I were converting NTSC to PAL, I wouldn't do it by speeding up the clip. It's the wrong way to go. I would do a frame-rate-conversion, using an application like JES Deinterlacer, or the set of Natress filters for FCP.

If you have to do it this way, you probably have to do it by ear. I'm not sure the FCP pitch adjustment numbers correlate to any actual mathematical equation.
