The Audio Engineering Society held its second annual Plugfest this past November at NPR studios in Washington, with nearly a dozen manufacturers in attendance, each working toward the goal of audio interoperability. Telos Alliance Chief Science Officer Greg Shay was on hand, and says despite the attendees being competitors, there was a spirit of cooperation that made the event a success.Read More
In the past, audio processing and monitoring required the purchasing of multiple, specialized hardware to support each function in the air chain. But now, thanks to the increase in the speed of Ethernet connectivity, and IT-based processing power, many of these same processes can be condensed and supported over IP. Audio in particular is making a move to the IP realm with the recent AES67 standard bringing interoperability between manufacturers. Even with this standardization, Audio over IP (AoIP) is still not being used to its maximum potential in the broadcast space.Read More
Part 1: Nerves and Networking
At 11:59 P.M. on a Sunday in April, 2002, I was sitting on the thinly carpeted floor of the NAB convention hall watching as a software guru fed lines of code into his IBM Thinkpad. The next morning, the doors of the hall would open, and our newest product – a console surface with an IP-connected DSP mixing engine – would be displayed for the examination of broadcasters from all over the world.Read More
Topics: Audio over IP
If you’ve been paying attention the past few years (and even if you haven’t!), you’ve no doubt heard about AES67, the IP-Audio networking standard adopted by the Audio Engineering Society in 2013. The standard has been a topic of conversation nearly everywhere since it was ratified.Read More
When the Audio Engineering Society published the AES67 standard for Audio over IP in September 2013, it symbolized the culmination of years of development work by people across the broadcast industry. But for Telos, it symbolized not just an industry standard, but the realization of the vision of our founder, Steve Church. As such, we were proud to have been involved since the project’s inception, and have seen it through to fruition.
Greg Shay, Chief Science Officer at Telos, began working on Audio Over IP (AoIP) 18 years ago in order to help the professional audio community close the loop on a pressing challenge: moving large amounts of audio data more efficiently, while retaining sonic quality and integrity. After joining Telos Systems in 1996, Shay worked with Steve Church and Frank Foti of The Telos Alliance to make Audio AoIP a reality, combining the company's unique technology achievements with existing state of the art switches and networking solutions from companies like Cisco.Read More
Topics: Audio over IP
Since Axia invented AoIP in 2003, I’ve had tons of conversations about Ethernet switches — as you might imagine! Switches are the heart of any AoIP system, so it makes sense to know a bit about them. But a lot of the language concerning Ethernet switches is fairly impenetrable (even to experienced engineers). So I thought that a post encapsulating some things I’ve learned might be useful to those of you planning your next facility.

When Steve Church unveiled IP-Audio, the technology which became our Axia brand, at NAB in 2002 he told everyone his vision: all broadcast equipment speaking a common language of networked control and audio, finally doing away with soldered, single-destination audio circuits and the stupefying array of connectors that accompanied them. Steve’s desire – and ours – is that all broadcast gear should interoperate. And not just operate together, but do it easily, seamlessly and without drama.
Fast-forward to 2014: our customers tell us that we’ve made a bit of progress! We’ve come to refer to this synergy, this co-operation of broadcast gear, as an ecosystem – all parts working together in harmony, with the sum of the parts being greater than the whole.Read More
By now, you’ve likely heard that the Audio Engineering Society (AES) has ratified the AES67 standard, which defines how Audio over IP (AoIP) systems from different manufacturers should interoperate.
The question, now that there’s a published specification, is — where do we go from here?
You might be interested in knowing that the team here at Axia has been involved in helping create this vital interoperation spec since the very beginning. We helped create and sustain the effort to create an interoperability spec, as well as contributing our technology and experience, to make creating the standard easier. Being the first company to develop AoIP technology for broadcast studios allowed us to help in ways that companies that were newer to this tech weren’t able to.Read More
