Maybe someone may find this usefull.

I have attached xtl files to extract WEM sounds from both "base-generic-*.rmdblob" and "stream0-generic-*.rmdblob" files (only files which are atleast 100kb in size). The xtl files are compatible with game version 1.0.14.

Processing those WEM files will save you additional 200mb. I removed in total 5 of the WEM files which are not encodable, which leads either to infinite encoding the files (temp files will grow infinitely), or they are just finished instantly, which will lead to broken files if you decode them back to original.

Maybe you have to edit file paths.

Bad WEM files in question:

"base-generic\data_pc\audio\media\152227780.wem"
"base-generic\data_pc\audio\media\526830619.wem"
"base-generic\data_pc\audio\media\577391364.wem"
"base-generic\data_pc\audio\media\880082258.wem"
"base-generic\data_pc\audio\media\908534589.wem"

1. Command to extract WEM files with xtool

:WEM base-generic
if not exist "extracted_data\base-generic" (
mkdir "extracted_data\base-generic" )
xtool extract "aw2_base_generic.xtl" "base-generic-000.rmdblob" "extracted_data\base-generic"
xtool extract "aw2_base_generic.xtl" "base-generic-001.rmdblob" "extracted_data\base-generic"
xtool extract "aw2_base_generic.xtl" "base-generic-002.rmdblob" "extracted_data\base-generic"
xtool extract "aw2_base_generic.xtl" "base-generic-003.rmdblob" "extracted_data\base-generic"
