What is an AWB file?
An AWB file is an audio package used by various Sega Dreamcast, PlayStation 2, GameCube, and Wii video games developed by CRI Middleware. It contains ADX or ADX2 formatted audio that is typically used for sound effects, music, and dialogue featured in a game.
You can use VGMToolbox to unpack the AWB file in Windows. AWB files that contain audio saved in the ADX2 format store multiple .HCA or HCA-MX files. HCA files are encoded with the High Compression Audio (HCA) proprietary codec and HCA-MX files are encoded with the HCA-MX codec.
NOTE: AWB files are typically seen with .ACB files in the game installation directory.
