At SVG Europe Audio's Sports Audio Summit 2025, Olympic Broadcasting Services (OBS) sound design and audio manager, Nuno Duarte, and Karl Malone, NBC Sports and Olympics senior director of audio engineering shared their audio plans in the keynote Powder and ice: Looking ahead to the sound of Milano Cortina'. The pair each provided a preview of what we can expect to hear from the slopes.
Right now, OBS has crew and helicopters cabling the mountainous venues for the Winter Olympics which is set to begin on 6 February 2026. Milano Cortina marks the first Winter Games post-COVID, following Beijing 2022.
In his presentation, Duarte said Beijing was a very hard situation in which to work for the OBS team, and welcomed the prospect of operating his audio side of the massive operation this coming Games without restrictions.
OBS is working out of five key clusters across Italy, which is making this Games a huge remote operation. Duarte said that over the past four years improvements in remote production technology has greatly accelerated, which means that despite the logistical issues of working over such a wide area away from the IBC in Milan, it will be achievable.

Duarte drew attention in particular to the fact that while there is set to be over 8.3% more hours of content from the Winter Games, the IBC will be 25% smaller than in Beijing, there will be 16% less broadcast compound space at the sports venues, and there will be significantly less power being used.
That's what we're talking about, he said. There is another number that isn't here, that is time to set up everything. We have much less time to set up all the systems on the venues and that is having a big impact on all of us, Duarte added.
Immersive audio is a standard for OBS, along with a total IP infrastructure. There will be a lot of new people working for OBS on immersive audio, and Duarte is excited to work with them. The immersive audio and the IP will be invisible in many ways to rights holders, with hidden microphones and everything simply working on the day.

Karl Malone then took the stage. Malone said the network has 19 million viewers watching the Olympics on its primetime show, and they are ready to pull off a spectacular Winter Games following off the back of Paris 2024.
On audio for Milano Cortina, Malone said that for audio, Winter Games are a little bit better [for audio] because everyone loves the sound of snow and ice .
NBC will be on air for the Winter Olympics on 4 February, with the Opening Ceremony on the 6 February. However, the broadcaster is also producing one of its biggest home events Superbowl Sunday taking place on 8 February, which is going to tax its resources somewhat. Yet Malone said the broadcaster is ready to take on the challenge.
NBC will be working from 14 venues over seven locations:
Milan: Opening Ceremony, figure skating and short track, speed skating, hockey x2
Cortina: Women's alpine, curling, sliding
Valtellina: Snowboard and freestyle (Livigno x2), men's alpine and ski mountaineering (Bormio)
Val di Fiemme: Cross country, ski jumping
Anterselva: Biathlon
Verona: Closing Ceremony
Cortina d'Ampezzo: Sliding
Malone pointed out that some of the venues are six or seven hours apart from each other, however what they lack in easy logistics, they gain in spectacular scenery.
