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.
