XACT is a Microsoft audio authoring tool for Windows. An XACT wave bank groups multiple sound files into one runtime data file that can be included with a game.
The bank contains the audio data and information needed by the XACT audio system. It works with the other files in an XACT project, including sound-bank data that refers to sounds in the wave bank.
XWB files are associated with older Microsoft game-development toolchains, including XNA and DirectX-based development. They are legacy runtime assets rather than general-purpose audio files.
Use Microsoft XACT on Windows to work with an xwb file. The file is normally used through the XACT project that created it rather than opened as a standalone recording.
Because an XWB file is a game audio bank, common media players generally cannot open it directly.
Microsoft XACT can export compiled XWB wave bank files to other formats. To obtain standard audio, use the original source recordings from the XACT project.
Extracting individual sounds from an existing bank requires a tool that specifically supports that bank's XACT data; conversion is not always possible.
