Wwise *.BNK File Extractor

This is a C++ rewrite and extension of bnkextr originally written by CTPAX-X in Delphi. It extracts WEM files from the ever more popular Wwise BNK format and from Wwise PCK file packages (AKPK).

Use ww2ogg to convert WEM files to the OGG format.

Usage

Usage: bnkextr filename.bnk|filename.pck [/swap] [/nodir] [/obj]
        /swap - swap byte order (use it for unpacking 'Army of Two')
        /nodir - create no additional directory for the extracted files
        /obj - generate an objects.txt (BNK) or files.txt (PCK) file with the extracted data

The format is detected by the file signature, not by the file extension.

BNK Format

• See the original Delphi code for the initial file specification
• See the XeNTaX wiki for a more complete file specification
• See the bnk.bt file for 010 Editor specification
• See the bnk.ksy file by ADawesomeguy for a Kaitai Struct specification

PCK Format

• See the pck.bt file for 010 Editor specification
• Streamed and external files are extracted as <id>.wem
• Embedded sound banks are extracted as <id>.bnk and then unpacked into a directory of the same name
• If a package holds more than one language, every language gets its own directory
• Encrypted packages are not supported

Supported HIRC Events

• Generic event type logging
