AES67 is a technical standard for audio over IP and audio over ethernet interoperability. The standard was developed by the Audio Engineering Society and first published in September 2013. It is a layer 3 protocol suite based on existing standards and is designed to allow interoperability between various IP-based audio networking systems such as RAVENNA, Livewire, Q-LAN and Dante. It also provides interoperability with layer 2 technologies, like Audio Video Bridging (AVB).[2]

AES67 promises interoperability between previously competing networked audio systems[3] and long-term network interoperation between systems.[4] Since its publication, AES67 has been implemented independently by several manufacturers and adopted by many others.

Development[edit]

The standard was developed by the Audio Engineering Society beginning at the end of 2010.[5] The standard was initially published September 2013.[6][7][8][9] A second printing including a patent statement from Audinate was published in March 2014. An update including clarifications and error corrections was issued in September 2015.[1]

The Media Networking Alliance was formed in October 2014 to promote adoption of AES67.[10]

In October 2014 a plugfest was held to test interoperability achieved with AES67.[11][12] A second plugfest was conducted in November 2015[13] and third in February 2017.[14]

In May 2016, the AES published a report describing synchronization interoperability between AES67 and SMPTE 2059-2.[15]

In September 2017, SMPTE published ST 2110, a standard for professional video over IP.[16] ST 2110-30 uses AES67 as the transport for audio accompanying the video.[17]

In December 2017 the Media Networking Alliance merged with the Alliance for IP Media Solutions (AIMS) combining efforts to promote standards-based network transport for audio and video.[18]

In April 2018 AES67-2018 was published. The principal change in this revision is addition of a protocol implementation conformance statement (PICS).[19]

Adoption[edit]

The standard has been implemented by Lawo,[20] Axia,[21] AMX (in SVSI devices), Wheatstone,[22][23] Extron Electronics, Riedel,[24] Coveloz Technologies,[25] ALC NetworX,[26] Audinate,[27][28][29][30][31][32] Archwave,[33] Digigram,[34] Sonifex,[35] Yamaha,[36] QSC,[37] Neutrik, Attero Tech,[38] Merging Technologies,[39][40][41][42] Gallery SIENNA,[43] and is supported by RAVENNA-enabled devices under its AES67 Operational Profile.[44]

Shipping Products[edit]

Over time this table will grow to become a resource for integration and compatibility between devices. The discovery methods supported by each device are critical for integration since the AES67 specification does not stipulate how this should be done, but instead provides a variety of options or suggestions. Also, AES67 specifies Multicast or Unicast but many AES67 devices only support Multicast.
