spatialaudiometadata.h contains the following programming interfaces:
Interfaces
| ISpatialAudioMetadataClient Provides a class factory for creating ISpatialAudioMetadataItems, ISpatialAudioMetadataWriter, ISpatialAudioMetadataReader, and ISpatialAudioMetadataCopier objects. |
| ISpatialAudioMetadataCopier Provides methods for copying all or subsets of metadata items from a source SpatialAudioMetadataItems into a destination SpatialAudioMetadataItems. |
| ISpatialAudioMetadataItems Represents a buffer of spatial audio metadata items. |
| ISpatialAudioMetadataItemsBuffer Provides methods for attaching buffers to SpatialAudioMetadataItems for in-place storage of data. |
| ISpatialAudioMetadataReader Provides methods for extracting spatial audio metadata items and item command value pairs from an ISpatialAudioMetadataItems object. |
| ISpatialAudioMetadataWriter Provides methods for storing spatial audio metadata items positioned within a range of corresponding audio frames. |
| ISpatialAudioObjectForMetadataCommands Used to write metadata commands for spatial audio. |
| ISpatialAudioObjectForMetadataItems Used to write spatial audio metadata for applications that require multiple metadata items per buffer with frame-accurate placement. |
| ISpatialAudioObjectRenderStreamForMetadata Provides methods for controlling a spatial audio object render stream for metadata, including starting, stopping, and resetting the stream. |
Structures
| SpatialAudioMetadataItemsInfo Provides information about an ISpatialAudioMetadataItems object. Get a copy of this structure by calling GetInfo. |
| SpatialAudioObjectRenderStreamForMetadataActivationParams Represents activation parameters for a spatial audio render stream for metadata. Pass this structure to ISpatialAudioClient::ActivateSpatialAudioStream when activating a stream. |
| SpatialAudioObjectRenderStreamForMetadataActivationParams2 Represents activation parameters for a spatial audio render stream for metadata, extending SpatialAudioObjectRenderStreamForMetadataActivationParams with the ability to specify stream options. |
Enumerations
| SpatialAudioMetadataCopyMode Specifies the copy mode used when calling ISpatialAudioMetadataCopier::CopyMetadataForFrames. |
| SpatialAudioMetadataWriterOverflowMode Specifies the desired behavior when an ISpatialAudioMetadataWriter attempts to write more items into the metadata buffer than was specified when the client was initialized. |
