Object Based Audio - The first steps
Peter Poers The world of broadcast audio is about to reach new levels as we embrace the future in terms of Next Generation Audio (NGA). Although at this stage we can't be precise about what this will bring, we do know that some 3D Immersive formats are already under development and will find their way into broadcast production and distribution very soon. Unlike the world of relatively constrained channel based coding that we are accustomed to, these new codec systems will support more channels and/or object based audio coding. For the end consumer, there will be two major benefits - a greater sense of involvement or immersion and a degree of personalisation. That's what the promises are.

What happened to audio networking
Brad Price It may seem hard to believe, but audio networking has now been with us for over 20 years. In 1996, Peak Audio released CobraNet, the first system that used computer networking of some sort to transport audio.

Streaming and the need for continued innovation
Jon Schorah - new In a fast-changing world, audio producers need to adapt quickly in order to keep up. Media consumption is changing - fast. Almost without anyone noticing, we have passed the tipping point. Only a few years ago we were discussing streaming as an emerging technology; yet now, according to a recent Deloitte survey, streaming has overtaken live TV as the preferred viewing method in the U.S. YouTube viewing figures continue to surge.

Who really benefits from the Cloud?
Jayson Tomlin - new The transition to "the cloud" in our industry has been challenging. Why is it so important to have cloud technologies? What do customers really expect? The term "cloud" has been used to such an extent that it has diminished the real and actual importance of what's really going on - off-premise compute power.

TV Futures
Gemma Frith I used to hate audio. Every time we recorded audio on a location shoot, something seemed to go wrong. It was a nightmare. And because I didn't understand it, I avoided it and would do anything to not be responsible for recording sound. However, eventually it got to a point where I hated how much I hated audio more than I hated audio itself! It became frustrating that I couldn't get it right, and I didn't want to have to avoid it anymore; I wanted to become a master of audio. That may have been slightly ambitious, but still, I was going to try.

VR and 3D Audio - Ask The Experts
Pieter Schillebeeckx What's the difference between 2D & 3D audio? There are two parts to this question when it comes to audio for VR. The key difference is that 2D is a single horizontal slice,so when we're thinking 5.1 or traditional surround sound in a cinema that would be looked at as 2D,whereas 3D adds height information to this both above and below you. The second part to this question relates to static versus dynamic audio,and this goes for both 2D and 3D audio.

Audio
Pieter Schillebeeckx Audio monitoring has come a long way since its humble beginnings of a box with a speaker, a volume control and an analogue input. Today's high-end audio monitoring units boast an impressive array of I/O such as SDI, MADI, AES-3 and Analogue while offering a large amount of functionality such as accurate metering, loudness measurement, Dolby decoding, metadata analysis and video confidence monitoring. There is however a huge storm brewing in the world of broadcast in the form of video and audio over IP, which will turn everything upside down.

Sound Devices: My Choice For Everything Audio
Darren Brisker Ever since I can remember, I have had a passion and curiosity for sound and sound recording. For the past thirty years, I have had the good fortune of turning that desire into a career as a production sound mixer working on incredible projects, including three of The Twilight Saga films. During my three decades in the industry, I have always prided myself on using the best equipment available, in order to capture the best sound possible. Equipment selection is critical to success, and the game was forever changed when Sound Devices entered the mix.

Class: Multi - Channel Audio
Bruce Devlin If you're given a media file and it has 16 channels of audio then life can quickly become the opposite of boring, especially if it has to go to air quickly and the supplier is new. Put simply there are many ways in which the different channels can be laid out in the file, but there isn't a single overall standard for labelling them. Enter SMPTE ST 377-4 - the Multi-Channel Audio Labelling specification (MCA). It's really boring and this is a good thing.

Anthony Wilkins The world of broadcast audio is on the verge of a major revolution. Numerous 3D Immersive formats are under development and will find their way into the mainstream of broadcast production and distribution in the near future. Unlike the world of relatively constrained channel based coding as we are accustomed to (most commonly Left / Right for Stereo and Left / Centre / Right / Surround Left / Surround Right + LFE or Low Frequency Effects for surround), these new codecs will support more channels and/or object based audio coding. For the end consumer, there will be two major benefits from this new approach, a greater sense of involvement or immersion, and a degree of personalisation.

AERO.soft - Bringing audio monitoring and processing into AoIP
Martin Dyster 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.

The business case for media asset management
Kevin Usher You could argue that, so far, there have been two stages of commercial justification for asset management systems in broadcasting. First, it was a necessary evil: if broadcasters, production companies and other media organizations wanted to store content as filesat least some of the timethey needed a means of finding it again. Once broadcasters had a comprehensive index to all of their content, and could find clips and programs again quickly, there existed the potential to earn new revenues from them, ushering in the second stage. Video and audio recordings are among the principal business assets of broadcasters and production companies, and making the best use of those assets, by re-using them whenever possible, is simply good commercial sense.

Moving voiceovers into the 21st century
Leigh Emmerson There was a time when the only way to get a voiceover for your production was by contacting a voiceover agent who would obligingly send over a CD or two full of voiceover sparkle and you and your client would choose one, schlep on down to a studio and pay a small fortune to sit on a swanky sofa and watch said sparkle record your script.

Kevin Cook Ever since the new regulations in the UK on radio microphone frequencies were introduced in the UK at the end of 2012, the days were numbered for my trusty old Sony UWP series radio mic system (consisting of the URX-P1 UHF dual-diversity receiver and UTX-B1 transmitter). Whilst super-reliable and excellent quality, this combo is limited to channels 67-69 which the government sold off to expand the frequencies available for mobile phones (cheers!!).

Singularity - QA and compliance monitoring in one box
Martin Dyster The task of maintaining loudness-compliant, high-quality delivery for broadcast audio is no longer a question of simply using ones ears.

Maintaining a quality audio track using this disparate mix of audio elements is one part of the QA equation facing broadcasters.
