This archive contains all (I think) audio files that exist in the game. They are all converted to ogg, renamed with their original names, and placed in their original directories for easier location of that effect/music/ambiance you're looking for. 

Instructions for replacing audio here (WEM): http://nomanswiki.ga/Replacing_Sound_Files
