AES67-2023, "AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability" has been published

High-performance media networks support professional quality audio (16 bit, 44,1 kHz and higher) with low latencies (less than 10 ms) compatible with live sound reinforcement. The level of network performance needed to meet these requirements is typically available on wired local-area networks and is achievable on enterprise-scale networks, but is generally not available on wide-area networks or the public internet. 

The most recent generation of these media networks use a diversity of proprietary and standard protocols. Despite a common basis in Internet Protocol, the systems do not interoperate. 

This standard provides specific recommendations for interoperability. The standard focuses on defining how existing protocols are used to create an interoperable system. No new protocols have been developed to achieve this.
The standard is expected to be useful for commercial audio applications including fixed and touring live sound reinforcement. It is also expected to be useful for distribution within broadcast, music production and post-production facilities.
This standard depends on established network protocols (see clause 2). These protocols can include additional options that are not required by this standard. Robust implementations of AES67 will tolerate these additional options.

Any behavior details not described in the main part of this standard are in some cases clarified in Annex G (PICS), by means of the respective evaluation criteria.
