Editing Audio files - OpenNaja/cobra-tools GitHub Wiki

When editing audio files you must first install WWise. the files used by the game are .wem format which can be converted from .wav files using WWise software.

once you have a .wav file you want to convert to .wem, follow this video tutorial: wav to wem conversion tutorial using WWise

backup your ovl and aux files

unpack your audio ovl (with the aux files present in the same folder) and identify which .ogg file you want to replace. (if you have errors unpacking the oggs, select show temp files to export the vanilla files as .wem instead to obtain the filenames)

rename your converted .wem file to match the ogg you want to replace.

inject the wem file and save over the old ovl.

place the new ovl and aux files into the game directory
