What is an XWMA file?

An .XWMA file is an XWMA Audio file.

XWMA Audio is a Microsoft audio file format designed for use with the XAudio2 sound system. It serves as a compact, compressed audio container that wraps Windows Media Audio (WMA) bitstreams so they can be efficiently streamed and decoded in real time by games or other media applications on Windows.

Files of this format are created by tools or runtimes that generate audio assets intended for playback by XAudio2. They hold compressed WMA audio data - typically WMA version 2 - inside a RIFF-style container, along with auxiliary data like packet size or seek-table information to allow seeking and efficient streaming. During playback, XAudio2 uses the file's format headers to allocate and decode audio into PCM output for output to speakers or mixers.

A basic XWMA Audio file begins with the standard four-character code "RIFF" at offset 0, indicating the RIFF container, and contains an "XWMAfmt" header at offset 8 to denote that it is the xWMA variant.
