It builds on D4.1 “Requirements for representation, archiving and provision of object-based audio”. It lists the formats which are selected for ORPHEUS and describes the interim status of the implementation of these formats. On the production side, formats like BW64, ADM, NMOS, UMCP are used and explained. BW64 is also used for archiving. For provision or distribution MPEG-H and AAC + ADM metadata are selected. Both solutions use MPEG-DASH for streaming.
