It's a very complex process to extract the phase files. In fact, I wouldn't be able to explain it all by myself. It took me days to figure it out (even with the turorials). Then you would need to locate the .mid files (for music) or .wav files (for sound effects) that are needed and convert them to .ogg (for the wiki) using some kind of audio conversion software.

Anyway, I don't think the sound files are a real high priority right now.
