Alright, so:

English audio = correct pitch

French audio = correct pitch

German audio = pitch speeded up

Italian audio = pitch speeded up

Spanish audio = correct pitch

If you want, you can send me the full audios, i'll change them to 23,976 fps with the right pitch for each one. ;)

About your audio capture, i was wondering if you used any auto gain compressor? How did you record these 5 different audios from your LDs? Because on some of them i can hear some volume variations and it seems it's due to an auto gain compressor who reduces every sounds that are too loud and creates a strange mix on the audio track.

Here's a little example where you can hear all the differences, it's in French but i guess it's not a problem. In this scene the best part to notice the auto gain compressor effect is when Luke and Ben are walking you can still hear the music from the cantina. Also, when Han is speaking there are some other volume variations. Pretty bad effect.
