AES67 is an open standard for audio over IP and audio over ethernet interoperability. The standard was developed by the Audio Engineering Society and 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]

Adoption[edit]

The standard has been implemented by Axia,[16] Wheatstone,[17][18] Riedel,[19] Coveloz Technologies,[20] ALC NetworX,[21] Audinate,[22][23][24][25][26][27] Archwave,[28] Digigram,[29] Sonifex,[30] Yamaha,[31] QSC[32] and is supported by RAVENNA-enabled devices under its AES67 Operational Profile.[33]
