Choosing a Baseline AoIP Protocol

By Marty Sacks on Mar 22, 2017 1:45:00 PM

Since the AES67 standard was ratified nearly three years ago, a paradigm shift has occurred in the broadcast indus­try with AoIP becoming the topic both around the water cooler and in facilities around the globe.

By now, you probably already know and understand AoIP's benefits: It saves money. It makes for more efficient work­flows. It reduces the amount of equip­ment you need. It eliminates massive amounts of wiring. It leverages “off the shelf” IP-based components from the larger IT industry for easy integration.

Make a Proper IP Address Scheme for Your Livewire Facility

By Jeff McGinley on Mar 15, 2017 11:49:17 AM

Want to get started quickly and correctly with your new Livewire facility? Axia Support Engineer Jeff McGinley offers up an important tip for optimal operation.

One of the first things to consider when planning your Livewire installation is a proper IP address scheme. We recommend reserving a small block of IP addresses per studio, and then assigning the same IP address to identical devices.

5 Tips for Converting to an AoIP Studio

By Addison Burnside on Mar 15, 2017 11:20:00 AM


If you’re a general manager, considering an Audio over IP network for your facility makes sense. The technology is faster, cheaper, and better than previous methods to build broadcast facilities. By converting to AoIP, you not only tap into the power of current technology, you allow your facility to leverage the enormous universe of “off the shelf” IT devices that are used worldwide, and not just in the broadcast industry. Here are our top five considerations for general managers thinking about a move to Audio over IP.

TWiRT 336 - Hands-On AES67 with Patrick Killianey

By Kirk Harnack [TWiRT] on Feb 11, 2017 1:00:00 PM

Perhaps you’ve heard of AES67 for IP-Audio. It allows cross-connection of different, competing AoIP standards like Ravenna, Dante, and Livewire+. But until you actually try connecting audio devices together, AES67 is just a standard on paper. IP-Audio expert, Patrick Killianey from Yamaha Pro Audio is here to explain real-world AES67 from our recent technology demo

Harnessing the Full Potential of Audio over IP

By Martin Dyster on Feb 8, 2017 11:00:00 AM

Martin DysterThere is a misconception in the broadcast space that media outlets must wait for video over IP to mature before fully embracing an audio over IP (AoIP) infrastructure, but this is not the case. AoIP technologies have been stable for some time and today can provide the flexibility, reliability, and connectivity needed to deploy audio separately from video. Before the introduction of SDI video with embedded audio, video and audio had been handled separately for years. Although embedded audio seemed like a step forward, it did not reduce lip sync issues, and associated metadata is still easily separated from the audio. Since metadata is an increasingly essential part of new audio services, this becomes a major problem.

Radio Free Asia: Axia Early AoIP Adopters

By Tom Vernon on Oct 5, 2016 1:30:00 PM

As Axia celebrates the 13th anniversary of our invention of AoIP audio, we like to look back and acknowledge some of our early adopters, those brave souls who purchased Axia gear at a time when breaking from AES3 or analog and going with IP audio represented some serious risk taking. One of those was Radio Free Asia (RFA), a nonprofit international broadcaster with its headquarters in Washington, DC and satellite studios throughout the Pacific Rim. RFA broadcasts in nine languages, via shortwave, satellite transmissions, medium-wave, FM, and streaming online. Most of the broadcasts are in Mandarin Chinese, which is broadcast twelve hours per day. We spoke with RFA's CTO, David Baden, who has recently returned from India, where he set up the remote equipment for Radio Free Asia's live coverage of the Tibetan elections.

The Case for AoIP Interoperability and the Rise of AES67

By Martin Dyster on Feb 29, 2016 4:58:00 PM

The global television broadcast community is poised at the brink of the next great revolution in technological advancement – audio and video over IP. The great leaps that we’ve witnessed over the last 50 years, from black and white to color, mono to stereo, analogue to digital, 4:3 to 16:9, SD to HD and from stereo to 5.1, have benefitted the viewer at home each step of the way, and has been embraced with the purchase of the latest TV or Home Cinema system. However, in the backrooms of TV stations, broadcast engineers around the world have toiled over system designs, white papers and equipment catalogues while manufacturers have raced to bring out the next best widget designed to do the job.

AES67 Breaks Out at ISE 2016

By Dave Sarkies on Feb 17, 2016 3:15:00 PM

Typically, when you think of a trade show in Amsterdam, you probably think IBC. Certainly the late-summer show is an important convention, but one geared specifically to broadcasters. Integrated Systems Europe (ISE), on the other hand, is aimed at the larger international Audio Video industry, with an emphasis on A/V technologies for live performance settings and business applications – anything from boardroom videoconference systems to the latest speakers for live venues.
