SpatDIF, the Spatial Sound Description Interchange Format is a light-weight, human-readable syntax for storing and transmitting spatial sound scenes, serving as an independent, cross-platform and host-independent solution for spatial sound composition. The recent update to version 0.4 of the specification introduces the ability to define and store continuous trajectories on the authoring layer in a human-readable way, as well as describing groups and source spreading. As a result, SpatDIF provides a new way to exchange higher level authoring data across authoring tools that help to preserve the artistic intent in spatial music.
