Radio TechCon 2021 – catch up videos
Hosted by: David Lloyd
Videos sponsored by: Broadcast Bionics
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.
Unwrapping BBC MakerBox
MakerBox from BBC Research & Development is the community where the weird and wonderful collide! Having developed new tools, the BBC wants to share what it’s learned with the community looking to innovate at the leading edge of broadcasting.
Senior Product Manager Laura Harrison and Lead R&D Engineer Jon Francomb from the BBC explain the MakerBox platform, where there are currently six tools available for you to try.
Check Out My Tune
Ever tried mixing Indian music? Regina Balachanthiran discovered that most music editing software can’t handle it – so she taught herself to code and set out to solve the problem.
Hear from Regina how she created her own plugin to handle Indian music ragas, and put your own tonal detection skills to the test!
LBC’s Latest Brilliant Creation
Global Engineers Jon Crew and Ioana Barbu, along with Will Batchelor, LBC’s Studio Video Producer, show you behind the scenes of Global’s Video and Radio studio located at 4 Millbank. They’ll show you how it was built, how the requirements suddenly changed during lockdown and the work that’s gone on in the last 18 months to perfect the workflow and get the very best out of the technology and content.

Sessions from Monday, 30th November 2020 – virtual event
Watt now? Watt if? The Hidden Power of Radio
There are various studies investigating the environmental impact of digital technology and services, but limited research dedicated to radio broadcast and listening. With changes to the radio industry on the horizon, such as a potential digital switchover or greater uptake of internet-connected devices, it’s important we understand how both industry and consumer decisions could impact the environment.
In this session, Chloe Fletcher from BBC R&D will explore how much energy is currently needed to prepare, distribute and consume BBC radio services, and how this may change over the next 20 years.
Multitrack
The Multitrack Audio Fellowship helps people from under-represented backgrounds find paid internships within the radio industry. In this session, Lisa Hack gives a brief introduction to the scheme and explains how technology teams can help.

Times Radio: Plandemic B
Launching a new speech radio station on a tight deadline is tough. Where are the studios going to be? How will the staff be trained? Are there enough supplies of tea and gaffer tape? Times Radio had to cope with all of these challenges – and then along came Covid-19.
One year on from the launch, take a look back with Lead Stations Engineer Chris Thame to find out how the team managed to get on air whilst staying 2m apart.
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.
DAraBic
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.
Whether you are freelance, employed or thinking about making the leap, discover what you need to help you make sound financial foundations today and to deliver on your goals tomorrow.
