ISpatialAudioMetadataItemsBuffer interface (spatialaudiometadata.h)

  • Article

Provides methods for attaching buffers to SpatialAudioMetadataItems for in-place storage of data. Get an instance of this object by passing a pointer to the interface into ActivateSpatialAudioMetadataItems. The buffer will be associated with the returned SpatialAudioMetadataItems. This interface allows you to attach a buffer and reset its contents to the empty set of metadata items or attach a previously-populated buffer and retain the data stored in the buffer.

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.
