Best setting to use for pitch shifting a stereo mix?

Can someone advise me of the best settings to use (in Wavelab 7) to pitch shift a stereo track up or down 2-3 semitones?

Since it depends on the audio material, you have to make tries and checks with the various options.

Thanks PG, I’ve been trying different settings and it’s subtle the differences. Because it’s a pop track I think the frequency localization settings on “Best” seems to be the best.
