History meets modernity at Prague conference
- Details
Immersive audio was the theme of this year’s SDC. Prague was an appropriate location, as the city’s long history of opera and classical music has seen many venues built with acoustics in mind. It was in the newest of these - the O2 universum, opened just six weeks earlier - that the conference took place.
Featuring a wide range of conference facilities and a 4,500-seat sports arena, the O2 universum staged demonstration immersive sound systems in both the largest conference room and the arena, as well as comparing them to a large format Nexo L-R line array system flown in the arena.
SDC 2019 featured a wide range of different presentations and demonstrations. These included the Prague Music String Quartet demonstrating the benefits of acoustic room enhancement using Yamaha’s AFC4 active field control system, followed by a stuffed chicken being sent flying around the room, its clucking tracked by the AFC4 system.
Other sessions saw the arena AFC4 system used to demonstrate how stage tracking heightens the experience of theatre and live music, as well as how regenerative audio systems can be used to boost the atmosphere at sports venues.
Seminars on system design and finance for large arenas were hosted by Nexo, while sessions on acoustic measurement and analysis, digital networking, EN54 certification in stadiums and arenas, remote conferencing, education in production management, certification workflows, artificial intelligence-based voice assistance and the huge, once-in-a-generation Fête des Vignerons, - which used 11 Yamaha Rivage PM and Nuage digital mixing systems - were also on offer.
In between the sessions, guests were invited to enjoy a fully-immersive, 3D virtual reality tram ride through Prague. This was recorded using Yamaha's ViReal 64-channel spherical microphone array, the sound being played back through Yamaha headphones accompanying video on Oculus Go headsets.
They also experienced the real thing, taking a historic tram to the 114 year-old Municipal House, a celebrated concert venue which is home to the Prague Music Orchestra. Here a recital by the Prague Music String Quartet in the Sladkovsky Hall was followed by a lively dinner. The Smetana Hall features a Nexo STM line array system for amplified concerts, installed earlier in 2019.
