Simone Lombardi talking on stage
Plugins are used for controlling the audio and broadcasting live. A system that makes Simone colleagues fall off there chair with how resilient it is.

Simone Lombardi talking on stage
Simone Lombardi says “5-10 years ago live festival sound would be less critical. Now audiences expect studio polish even if live and artists care a lot about their sonic identity.”
Enter, AI Stem Separation
#radtechcon

We’re off to Glastonbury - as you’ve never heard it before. Simone Lombardi is explaining how the BBC is using new AI techniques to separate stems live. This is much harder than it sounds! #radtechcon
An engaging afternoon at Radio TechCon comprised a mini masterclass on AI in audio, DAB+ multiplexers as a smoothie analogy, Sveriges Radio's News Search, cleaning up an audio muddy Glastonbury, a peek into the IET archives & more ... & cake #radtechcon

BFBS presenting at RadTechCon 2025
James Smith & Angie Avilanos from @bfbs.com @forcesnews.com tell us about putting together coverage of an ESports tournament for the British Military. The games might be virtual, but the logistics involved in putting together the live broadcast were as real as any irl live sports event. #RadTechCon
BFBS is sharing what they launched from launching an esports tournament. This is a booming industry and there is a real need for the technical skills that radio tech people already have. Potential career move for you…? #radtechcon
This is a session that I would have liked to see (in the middle of a similar project as we speak.) Can I request this as the first video in the queue when you start publishing them.... #radtechcon
Photo of a fruit smoothie analogy of DAB multiplexing.
Richard Johnston and Richard Knight are giving a DAB multiplexing explanation using a fruit smoothie / blending analogy. A very Rich session about moving the location of the smoothie maker and the interaction between engineering and commercial. #RadTechCon
Arqiva is up talking about DAB. "I realise that some people in this room invented it!" say Richard Knight.
He's using an analogy of a fruit smoothie to explain how multiplexing works. #radtechcon
Key takeaways for AI
My Dr said take aways are bad for you. Not these ones, from Marianne on AI… #radtechcon
Marianne on stage with AI robot picture behind.
Mini masterclass time now - a chance to revise an industry topic from scratch. Marianne Bouchart has travelled from France today to talk about AI for audio. The slides were being updated ‘til the last second as the information changes so quickly. #radtechcon
A fantastic morning of speakers at Radio TechCon '25 including how RTP Antena 1 remained on air in the Iberian blackout, BBCWS using solar power at transmission sites in Ghana and how Castledown FM community radio moved studios seemingly seamlessly at short notice on a shoestring budget. #radtechcon
Slide advice for taking decisions: Be present, and separate information gathering from decision making.
Key takeaways from James’ session. Be present, and separate information gathering from decision making. #radtechcon
The APGAR scale was invented by Dr Virginia Apgar to check newborn babies' health straight after birth. So NewsUK created the Prater scale (after Nick Prater) to help them work through broadcast incidents! #radtechcon
Great tip from James Taylor: if there's more than one person who could jump in to solve a studio fault, you should say 'I am doing x to resolve/investigate y' so that everyone else doesn't overlap with you. #radtechcon
Attention tunnelling: what happens when you are producing a show and don't actually notice what is going out on air, because you are *so* focused on doing your current task. #radtechcon
Slide about decision making, at radtechcon 25
From clouds to clouds. Pilot and Aviation expert, Dr James Taylor’s session, now taking off, is asking us to think about how we make decisions. #radtechcon
