AWB is an archive format used in Persona 4 Golden, Persona Q, and Persona 5. It was developed by CRI Middleware and is the successor of AFS. Sometimes AWB may contain sound filetypes such as ADX or HCA.
You can batch extract AWB files using VGMToolbox.
Under VGMToolbox > Misc.Tools > Extraction Tools > Common Archives, choose CRI ACB/AWB Archive Extractor. Then, drag and drop ACB/AWB files. The contents will be dumped to a folder.
