ISpatialAudioMetadataWriter interface

Provides methods for storing spatial audio metadata items positioned within a range of corresponding audio frames. Each metadata item has a zero-based offset position within the specified frame. Each item can contain one or more commands specific to the metadata format ID provided in the SpatialAudioObjectRenderStreamForMetadataActivationParams when the ISpatialAudioMetadataClient was created. This object does not allocate storage for the metadata it is provided, the caller is expected to manage the allocation of memory used to store the packed data. Multiple metadata items can be placed in the ISpatialAudioMetadataItems object. For each item, call WriteNextItem followed by a call to WriteNextItemCommand.

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.
