Audio-over-IP Networking Joins the World

While a substantial part of our team is heading or already at AXPONA, ready to indulge in the pleasures of another great consumer audio show with the highest quality experiences of speakers and headphones, audioXpress is bracing for another avalanche of substantial technology announcements resulting from the also approaching National Association of Broadcasters (NAB) convention in Las Vegas.
And there's no possible comparison in terms of product announcements at Axpona with the number of releases that have already inundated our inbox for the past seven days. Among the most notable trends from Las Vegas is clearly that of very high quality and High Dynamic Range (HDR) images, from UHD 4K and 8K television to the world of digital cinema, 360 video, and virtual reality production. It's like the world of visuals is entering warp speed, with all the main brands - from GoPro to Blackmagic, Sony and Canon - announcing new amazing cameras for every budget and production needs. Together with new high-quality cameras, there's significant improvements in post-production solutions and especially storage, with Thunderbolt 3 dominating the announcements, as expected.
Audinate is promising that its Dante Domain Manager software will make "audio networking more secure, more scalable, and more manageable than ever before."
A show such as NAB covers many fronts, most of which are not exactly the focus for audioXpress, but I cannot avoid mentioning that, with all this crazy-fast evolution in the imaging world, there's another revolution taking place. The world is transitioning to everything-over-IP - from production to contribution and distribution - with the also-fast transition to music streaming services and increasing use of cloud platforms for music recording and collaboration. And when the broadcast and media industry discusses this new networking world and on-demand access to content at NAB, audio is a fundamental part, and a lot is happening on this front.
As audioXpress has extensively covered both in print and online, the world of audio-over-IP networking has been particularly dynamic in professional audio applications, from commercial audio installation to live sound production and now expanding into studio recording and broadcast applications. On that front, Audinate has been particularly successful with its Dante AoIP technology powering products available from hundreds of audio manufacturers around the world. As Audinate states, its vision is "to revolutionize professional and commercial audio for the 21st century," replacing traditional analog audio cables by "transmitting perfectly synchronized audio signals across large distances, to multiple locations at once, using nothing more than an Ethernet cable."
Together with Audinate, there are several other AoIP protocols that have achieved significant success, each in its specific field of application. Among those, RAVENNA is recognized as the most powerful and versatile, from broadcast to high-quality recording applications - and probably one of the few to actually make inroads into high-end consumer audio. Both Dante and RAVENNA will be prominently featured in many demonstrations at NAB 2017, together with The Telos Alliance Livewire+ audio networking technology, which is a solution adopted by radio stations all over the world. Dante, RAVENNA, Livewire+, and QSC's Q-LAN are all compatible with the AES67 interoperability standard and now have solutions available in the market. This means all the AoIP solutions are now able to exchange audio among them, creating a robust infrastructure that the broadcast market in particular is promoting as a foundation for its IP future.
Andreas Hildebrand, Senior Product Manager at ALC NetworX, RAVENNA technology promoter

But the work is far from over. As Andreas Hildebrand, Senior Product Manager at ALC NetworX (the RAVENNA technology promoter), told us recently in Frankfurt - it is very important to continue and even increase the interoperability efforts and evolution of the AES standards, as the video industry also evolves to an all-IP approach. At NAB 2017, there will be far more demonstrations and activity around the ever-present and constantly evolving theme of interoperability than any other show. Also RAVENNA is promoting AES67 interoperability demos together with Lawo, Genelec, Riedel, Merging, Sonifex, Ward-Beck, DirectOut, Coveloz, Archwave, Digigram, ALC NetworX and ARG, and even running a live interop demo with a Yamaha mixing desk based on Dante, using its new RAV2SAP software conversion tool that makes life easier for people wanting to connect RAVENNA devices to other AES67 devices, and Dante devices in particular.
Merging Technologies also introduced another important tool - the ANEMAN Audio Network Manager software, a completely new and easy way to patch AES67 audio and more. This AoIP network management tool is still being developed but already shows lots of potential. In fact, it brings to the RAVENNA/AES67 side some of the same convenience that Audinate is promising to offer with its Dante Domain Manager, an enterprise-wide, IT-Grade platform to simplify network management, announced earlier this year and scheduled to be available later in 2017.
But more importantly, the work is just starting to guarantee fully practical audio streaming workflows with the new standards, such as the SMPTE2022-7 and SMPTE ST2110 Standards for Professional Media over IP Networks, and the ongoing work on synchronization and timing issues with ST 2059. One of the places to see those demonstrations in practice will be the NAB IP Showcase (located in the North Hall of the LVCC, booth N4824), designed to provide a unified, industry-wide view of the ever more important role of IP in the broadcast industry by using equipment from more than 60 manufacturers. The demonstration intends to show that real-time media production using IP networks is now a practical, flexible, and efficient reality.
Promoting the AoIP concept, Genelec has created special RAVENNA-green 8430 IP monitors for display at trade shows.
The IP Showcase, demonstrating interoperability of four parts of the new SMPTE ST 2110 standard, pertaining to video, audio, control, and metadata, represents an unprecedented joint effort by the most important industry consortiums, associations, and standards organizations, such as the Audio Engineering Society (AES), the Alliance for IP Media Solutions (AIMS), the Media Networking Alliance (MNA), the Advanced Media Workflow Association (AMWA), the European Broadcasting Union (EBU), IABM (the international trade association for suppliers of broadcast and media technology), the Society of Motion Picture and Television Engineers (SMPTE) and the Video Services Forum (VSF), all major industry alliances.
Other initiatives on IP Video Delivery, promoted by The Alliance for IP Media Solutions (AIMS) will be particularly important at NAB 2017, with 15 related papers being presented at the show. As AIMS is making clear, the ongoing accelerated standards process needs to be followed closely since there's so much happening. AIMS' participation in the IP Showcase is part of its ongoing cooperative effort to establish a uniform approach to all-IP workflows based on industry standards and recommendations that are already established or are well underway.
A recent AIMS survey revealed that many AIMS members are moving quickly to bring products to market that are compliant with the SMPTE suite of standards for Professional Media over IP Networks (SMPTE ST 2110) by the end of 2017. SMPTE ST 2110 is currently in final draft stage and is widely projected as a fundamental development in a transition to full IP workflows in broadcast, based on common open standards.
The Alliance for IP Media Solutions (AIMS) and the Media Networking Alliance (MNA) are the two key associations to follow regarding AoIP and interoperability efforts.
Representing those efforts on the audio front, the Media Networking Alliance (MNA), established to promote the adoption of the AES67 AoIP interoperability open standard, says that its inclusion defining the audio element of the new SMPTE ST 2110 standard, "acknowledges the rapid and widespread adoption of AES67 in providing signal interoperability across all of the current leading IP based audio networking protocols." Michael Cronk, Chairman of AIMS, calls AES67, "a foundational standard for the broadcast industry."
"As one of the first standards bodies to address media over IP - initially with AES67 for audio and now with AES70 for control - The Audio Engineering Society is pleased to be a part of NAB IP Showcase," adds Bruce C. Olson, AES Standards Committee Chair. "Interoperability demonstrations and shared real-world experiences in the IP Showcase will include audio-based media and blended media, the latter where video content and AES67-compliant audio share a common IP carrier. The IP Showcase is an excellent opportunity to demonstrate publicly the benefits for broadcasters born of the collaboration between standards bodies and partner organizations promoting IP workflows."

Practical Test & Measurement
Sound Cards for Data Acquisition in Audio Measurements (Part 2)
By Stuart Yaniger
audioXpress June 2015 issue initiated a great series by Stuart Yaniger on "Sound Cards for Data Acquisition in Audio Measurements." As Stuart explains, "In this column, I will look at some of the available options and methods to create a low-cost system (emphasis on "low-cost") for lab-grade audio electronics measurements and provide some examples. I will skip the superb but expensive systems to concentrate on solutions within easy reach of budget-conscience hobbyists. The goal is to demonstrate how you can generate useful data, similar to the graphs and charts in the audio review magazines, but without the expense." This was the start of an insightful and entertaining series that we have now decided to share online following numerous request from members of DIY forums and many enthusiasts of test and measurement adventures that apparently kept searching for the topic in our website. In this second part, Yaniger examines sound card requirements. Since most sound cards are intended for gamers, home theater, and musicians, the article evaluates the criteria to decide what features to look for in a sound card targeted for audio measurement.
