If an AWB file is accompanied by an ACB file, then AcbEditor.exe can be used to dump the contained AT9 or ADX files. Simply drag the ACB onto the EXE. To repack, drag the resulting folder onto the EXE. You can get it here.

AWB Tools
The AWB Unpacker/Repacker is able to extract and repack AWB files without an associated ACB file. Extraction can be done by dragging the AWB onto the AWB_unpacker.exe, but repacking must be done through the command line. It can be found here.
