Actually couldn't decrypt around ~100 sounds, so if you can't find a sound what you looking for there is a change it's in that 100 sounds. Anyway if someone wants to try to decrypt them i can provide the extracted files. The files are revorbed oggs that means some of the sound players may not play all the files correctly (Like winamp), try to use a proper player which plays oggs properly, or convert them to mp3 (I didn't wanted to do that myself since it would make the pack size 3-4 times bigger). If anyone can find more demon like announder sounds like what you can find in the "!" folder let me know please, i would like to use thoose files for future development for my wow addon:
