Represents a buffer of spatial audio metadata items. Metadata commands and values can be written to, read from, and copied between ISpatialAudioMetadataItems using the ISpatialAudioMetadataWriter, ISpatialAudioMetadataReader, and ISpatialAudioMetadataCopier interfaces. Use caller-allocated memory to store metadata items by creating an ISpatialAudioMetadataItemsBuffer.
This interface is a part of Windows Sonic, Microsoft’s audio platform for more immersive audio which includes integrated spatial sound on Xbox and Windows.
