Radio AoIP 2016 A new eBook from Radio World is now available

“AES67 will change everything for pro audio.”

“No one will be left on a proprietary island.”

“Broadcasters do not build radio stations any longer, they build data centers that play music.”

“A new trend in AoIP will replace the model we’ve got now.”

That’s just a sampling of comments we gathered from users, manufacturers and standards experts for “Radio AoIP 2016,” Radio World’s latest supplement about audio over IP for radio broadcasters, the seventh in a series dating back to 2002.

We asked the experts about implications of AES67 and AES70; about how broadcasters such as iHeartMedia, Cumulus, Townsquare Media, Minnesota Public Radio and RadiOhio are using AoIP technology; how to avoid common issues or problems; and what we can learn from their interesting projects and “problems solved.”

It’s free; read it here!

AoIP: Where We Are, Where We’re Headed

New York Yankee Yogi Berra once said, “The future ain’t what it used to be.” Take that quote and apply it to Audio over Internet Protocol in broadcast facilities and other professional venues, and I’d have to say that Yogi would be wrong. The future is actually very bright indeed.

At Axia Audio — and the Telos Alliance at large — we were so convinced of the importance of interoperability between AoIP products that we put significant financial and technical resources into the work that led to the standard — AES67.

How Does AES70 Fit in the Studio? Think MIDI

IP audio network manufacturers have gone all out to develop complete studio environments, some of which include everything from control surfaces and talent stations to button panels and widget GUIs to specialty I/O devices and processors.

These systems are the backbone of the broadcast operation today because they provide complete control and access of networked audio and gear in one seamless environment. By building upon their respective audio network environments, manufacturers have been able to expand on AoIP capabilities and lower the cost of operation in many cases. read more

The AES Ratifies OCA as the AES70 Standard

The Audio Engineering Society has published the new AES70 audio over IP standard. Additionally, a report on the recently conducted AES67 interoperability Plugfest has been released. AES Standards Manager Mark Yonge explained AES70 “follows on to complement the AES67 audio over IP networking standard we published in 2013. It covers quite comprehensively the control and monitoring of audio devices over a network. read more

OCA Alliance MicroDemo, New Products on the Way

By SCN Staff On August 18, 2015

Simon Jones

The Open Control Architecture (OCA) Alliance has developed the OCA MicroDemo, a demonstration product designed to prove that OCA is a common remote control and monitoring language for digital audio networks that can run in lightweight hardware environments.

Developed jointly by OCA member companies Focusrite, Attero Tech, and Bosch, OCA debuted the circuit board at its booth during the 2015 InfoComm exhibition.


“The OCA MicroDemo is a demonstration product being co-developed by OCA Alliance members,” said Simon Jones, technology manager at Focusrite Audio Engineering. “Its primary purpose is to prove that OCA can run well in lightweight hardware environments. At this time, MicroDemo hardware development is complete and software development will be completed later this year.”


Alliance member companies also introduced products featuring OCA functionality at InfoComm15, including the PRS-40M14 OMNEO Interface from Bosch Communications and the four-channel “next generation” 10D and 30D installation amplifiers from d&b audiotechnik.


“With further new OCA enabled products, we are looking forward to transforming part of the OCA vision into reality: the simplified integration of a voice alarm system and an entertainment audio system from multiple manufacturers,” said Marc Weber, marketing group chair at d&b audiotechnik.
