Wakefield, UK (August 27, 2008)–NEP Visions has been using SoundField’s DSF-2 digital microphone to provide 5.1 ambience on its HD transmissions for a variety of European sports events.
This summer, NEP Visions, one of Europe’s largest independent outside broadcast facilities companies, also began working with SoundField’s recently introduced DSF-3 digital processor, which completes an entirely digital signal path from the SoundField microphone to broadcast, and forms the basis for the 5.1 surround sound audio feed NEP Visions supply to their HD broadcast clients.
As Visions’ deputy head of sound, Neville Hooper, explains, the company has been aware of SoundField for many years, and purchased its own analogue SoundField system last year, comprising an SPS422 microphone and a SP451 surround decoder, which sees regular use. But the company became serious with SoundField technology when the DSF-2 digital microphone was launched in 2006. “We undertook trials of several different systems in the days before regular HD broadcast services were launched, trying to find the best way to produce an HD-compatible 5.1 audio feed for use with our HD broadcast clients like Sky Sports,” comments Hooper.
“We just weren’t happy with some of the cheaper multi-capsule solutions, which produced all manner of phase problems when the surround sound signals were folded down to stereo. But SoundField’s system behaves like a point-source microphone, produces no phase artefacts, and gives you a simultaneous, phase-coherent stereo signal, which is essential, because of course stereo is still the most important standard for nearly every mainstream broadcaster. The DSF-2 gave us the best results of all the systems we tried.”
Since then, NEP Visions have used Sky’s DSF-2 systems on its regular work for the international satellite broadcaster, including this year’s NFL American Football games at Wembley. When working for other broadcasters, it has switched to its own analogue SoundField SPS422/SP451 combination to create its surround sound output.
