Remarks
This is a legacy XMA1 format structure. The information provided should be used for reference only and not be used in new content.
XMAWAVEFORMAT was the structure used in XMA version 1 files. XMA2WAVEFORMAT was used in early XMA2 files. It is not placed in the usual fmt RIFF chunk but in its own XMA2 chunk. For more information about XMA2, see Overview of XMA2. For an overview of the audio architecture of XBOX One, see The sound of the future: The audio architecture in XBOX One.
