SpatDIF, the Spatial Sound Description Interchange Format, is an ongoing collaborative effort offering a semantic and syntactic specification for storing and transmitting spatial audio scene descriptions. The SpatDIF core is a lightweight minimal solution providing the most essential set of descriptors for spatial sound scenes. Additional descriptors are introduced as extensions, expanding the namespace and scope with respect to authoring, scene description, rendering and reproduction of spatial audio. A general overview of the specification is provided, and two use cases are discussed, exemplifying SpatDIF’s potential for file-based pieces as well as real-time streaming of spatial audio information.
The full paper will be made available when the conference takes place.
