Sessions from Monday 29th November 2021 – virtual event

Stay tuned for weekly videos from Radio TechCon 2021…

A Talented Future for Radio

How do we attract new talent to broadcast engineering – and how do we make them stay?

Engineers-to-be have some much choice when it come to Apprenticeships. Broadcast engineering companies are competing with the likes of Google and Facebook, as well as related industries with higher pay. So how do we attract new talent to radio? And what do we need to do to ensure newer engineers stay?

Dilani Selvanathan began her career at the BBC before moving to work in other fields. She has already been recognised by the IET for her work in encouraging young people into engineering. She shares her insights about what we’re getting right – and what our industry needs to do to attract the engineering talent of the future.

Covering South Africa with Digital Sounds

How do you cover a country with a land area 5 times that of the UK with Digital Radio?

At 1.22 million sq kilometres, providing adequate radio coverage presents significant challenges.

After some years of deliberation the South African authorities have announced that they will introduce Digital Radio to their country. This will be achieved by a unique combination of Digital Radio Mondial and EU147 DAB digital platforms. These two digital broadcast standards will provide both the long range and local coverage that this vast country requires.

Aldred Dreyer from the SA DRM Group and Radu Obreja from the DRM Consortium tell the story of their contribution to this massive undertaking.

Boom without a Box

The team at Boom Radio decided to build a radio station… with no studios, no buildings, no racks room and at the height of a national lockdown when visits to presenters’ homes weren’t possible. 

Hear from David Lloyd and Quentin Howard about how Boom Radio solved an alphabet soup of technical and human challenges, from Acoustics to Zetta, and launched one of the most successful new stations in recent years.

Unmixing: Having Your Cake AND the Ingredients

Next Generation Audio (NGA) allows speech and other sounds to be kept separate until the final mix is created in the consumer device, enabling a range of personalisation options.

But a great deal of ready-mixed content already exists, and new content is seldom created with different sounds kept separate. To offer the benefits of NGA within existing workflows we need to ‘unmix’ the audio.

Speakers Iain McClenaghan (BBC R&D) and Aimée Moulson (Fraunhofer IIS) explain how this source separation is achieved using artificial intelligence techniques.

They then tell us how well it actually works!

Smarter Syndication – A Tale of Splits, Sockets and Carson Daly

How can a syndicated show be recorded and delivered differently in 2021 to allow each station taking the show to have a bespoke version?

Gav Richards is the host of 10 Most Wanted, a nightly syndicated chart show with a difference… Each station that takes the show gets their own station namechecks, mentions of the local area and presenters, and can run to time with whatever requirements the station has.

This is all achieved through a system developed by Gav which we see in action in this Radio TechCon 2021 session. Watch now to learn more of the concepts involved.

Mini-Masterclass: Latency – the talk you’ve been waiting for

Latency has become especially topical over the last couple of years!

When working at a distance we are faced with technological and performative processes that disrupt synchronisation. Limitations and constraints that might cause frustration can in fact be exploited for new creative strategies for musicians, broadcasters, podcasters and other producers of time-based media. These creative strategies not only accommodate the inconveniences of latency and acoustic feedback but can actually help us adapt and transform how we engage in real-time online.

Rebekah Wilson is a composer, musician, technical co-founder and CEO of Source Elements. In this mini-masterclass, Rebekah shares her insights and work on addressing latency to optimise real-time remote collaboration.

It Is Rocket Science – How NASA Does Sound

NASA broadcasts thousands of hours of televised and internet-streamed content from space. But what is happening behind-the-scenes? How does the world get to hear the instructions for ground control, and who teaches the astronauts how to use a microphone? NASA’s Emmy Award-winning sound engineer Alexandria Perryman reveals all.

The Internet Monkey Cage

The pandemic has affected all of our workflows, as staying at home became the new going out. But how does that work when you normally have lots of guests in a studio …or need to record an audience laughing in real time?

The BBC’s Matthew Page tells the story behind its Pre Rec and Virtual Audience systems, with a special guest contribution from Robin Ince from the Infinite Monkey Cage.


The ability to display station names, programme types and dynamic text is very much part of the appeal of DAB and DRM as a modern digital radio technology, but if they are going to become truly global and ubiquitous, then they will need to be fluent in more than Latin script.

The BBC’s Abdallah al-Salmi explains the complexities of Arabic script display and how the ETSI standards of DAB and DRM have been updated in order to support the growing requirements of broadcasters across the world.

Freelance Your Future

The last couple of years have seen huge changes in our industry. Many people have been made redundant, and others have found new ways of working due to the pandemic.
