Note: This tool is primarily used by the PES modding community to convert .wav files to .adx (the audio format used by PES games) or to extract/import commentary, chants, and music.
Open the target .awb file from your game directory (usually found in the dt40_all.cpk or similar archive).
Note: Always check the readme; some packs require the converter to extract the files into the correct common folder.
Conclusion
Edit → Normalize to set uniform loudness (helps stadium chants blend).
