The ORPHEUS consortium has identified a number of standardisation bodies and contribution areas which are highly relevant for ORPHEUS. The targeted standardisation bodies have in common that they develop standards related to object-based audio. Thus, ORPHEUS is focusing its standards-related efforts to the selected bodies, in order to achieve maximum impact.
The standardisation activities by ORPHEUS so far have been focused mainly on four organisations, including three standardisation bodies – ITU-R, ISO/IEC MPEG, and ETSI-DVB – and the EBU as a standards-related organisation. In Q4/2017, new activities in the AES Standards Committee have started. In respect to these standardisation bodies, ORPHEUS partners performed the standardisation activities summarised in the table below.
| Standardisation body | Contributions | Involved partners | Standard impacted by ORPHEUS |
| ITU-R 6B | Work on updates on ADM Metadata | FHG, BBC, IRT | ITU-R BS.2076, ITU-R BS.2094 |
| ITU-R 6B | Contributions on a streamable version of the ADM | FHG, BBC, IRT | Not yet defined, under development |
| ITU-R 6C | Work on the topic of a standardised baseline renderer for object-based audio (RG33) | FHG, BBC, IRT | Not defined |
| ITU-R 6C | Work for standardisation of object-based loudness calculation | FHG, BBC, IRT | ITU-R BS.1770 |
| ISO/IEC MPEG | MPEG-H 3D Audio (audio codec) | FHG | ISO/IEC 23008-3 |
| ISO/IEC MPEG | MPEG-H, DASH (transport container) | FHG | ISO/IEC 23009-1 |
| ISO/IEC MPEG | Contribution to MPEG-I discussions on immersive media formats | b<>com | MPEG-I |
| EBU | Contributions to SP-FAR (Future Audio formats & Renderer) group meetings, planning of “Object Based Audio” workshop | BBC, IRT, FHG, b<>com | Does not apply, as EBU does not define formal standards |
| ETSI-DVB | Work on document ETSI 101154 to get a next generation audio part | FHG, BBC, IRT, b<>com | MPEG-H & AC-4 |
| AES Standards Committee | Contributions to drafting will be made, and guidance given, as becomes necessary to ensure compatibility with the ORPHEUS architecture, in particular with ADM (Rec. ITU-R BS.2076). | BBC | AES-X242 (Streaming audio metadata over IP networks) |
