Abstract

Personal devices with loudspeakers can be orchestrated to increase immersion from low channel count reproduction systems. A trial production was conducted to investigate the content creation workflow and delivery mechanism for orchestrated devices. The content (a 13-minute science-fiction drama entitled The Vostok-K Incident) included: a stereo bed; elements only replayed from auxiliary devices; and elements that could either be in the stereo bed or replayed from auxiliary devices. A bespoke production environment was established, including plug-ins for authoring the metadata needed to utilize the rendering ruleset. Ambiguity in the reproduction system, coupled with flexible and complex metadata authoring requirements, made the production challenging and time-consuming. Future work will focus on refining the production process and developing delivery tools.
