rs2-audio-extractor

Decode Wwise audio files to Ogg format while preserving original file names and project structure where possible.

Works with Rising Storm 2: Vietnam & Killing Floor 2. May also work with other games that provide Wwise metadata (txt) files.

Good performance by taking advantage of multiple CPU cores by using multiprocessing.

Usage

Show help:

extract.exe --help

Parse files in WwiseAudio and write output in output in Ogg format:

extract.exe "C:\...\WwiseAudio" "C:\output"

Troubleshooting

ww2ogg errors or errors opening decoded files

The program output directory will have paths longer than the max default Windows path limit.

Fix by enabling Win32 long paths and rebooting.
