Replacing audio of audience?

[singup]

Is it possible to add custom chants etc to the audio? I would like to make them louder.

Yes mate. You'd have to download Ravioli tools, use that to browse the game's sound files, find the sounds you want to edit/replace, extract them, then use Sound Injector to inject them back in after adding the sound ID to the data.xml file.
