The Audio Engineering Society today published AES67, an effort that has been watched closely by participants in the audio over IP and broadcast networking worlds. Work has been ongoing under the name “AES-X192.”
The document aims to provide “comprehensive interoperability recommendations in the areas of synchronization, media clock identification, network transport, encoding and streaming, session description and connection management,” according to the abstract.
“High-performance media networks support professional quality audio (16 bit, 44.1 kHz and higher) with low latencies (less than 10 milliseconds) compatible with live sound reinforcement. The level of network performance required to meet these requirements is available on local-area networks and is achievable on enterprise-scale networks. A number of networked audio systems have been developed to support high-performance media networking but until now there were no recommendations for operating these systems in an interoperable manner.”
As RW has reported, the document was being developed as part of project AES-X192 within a task group on high-performance streaming audio-over-IP interoperability, and the effort was led by Kevin Gross,a media network consultant with AVA Networks, which developed the CobraNet standard. About 100 members, including several major console and router manufacturers, took part in the project.
AES offers its standards free to members and sells them to the public. Look for more Radio World coverage about the new document shortly.
