TSL Products, a provider of audio
monitoring solutions, surround sound microphones and processors,
broadcast control systems and power management tools, is working with
BBC Sport to supply two SoundField X-1 Upmix/Downmix Processors

various audio elements that contribute to a sports programme, from
studio and location dialogue, commentary, voice overs, phone calls,
music, sound effects, actuality sound to crowd atmosphere will come
into us from a wide variety of mono, stereo and 5.1 sources,"
says Dave Lee, lead sound supervisor for BBC Sport. "With such
diversity of contribution quality and width, the sound supervisor is
tasked with mixing a show that immerses 5.1 viewers in the surround
sound atmosphere of the event whilst maintaining clear, consistent
imaging of dialogue and music.
SoundField X-1 anchors dialogue and reality audio to the front, while
offering near-instantaneous upmix/downmix processing. This is
essential during a live, action-packed broadcast, such as the World
Cup, as it helps to ensure that the sound will never fall out of sync
with the associated vision."
the World Cup, long periods of the transmissions use genuine 5.1
actuality sound and crowd atmosphere, along with panned commentary
and studio dialogue. However, when broadcasting out of match play
time, the majority of audio is stereo or dual mono content. BBC Sport
will route this audio material through a signal path to an X-1 in
upmix mode. The upmixed audio will then contribute directly to the
5.1 mix bus.

successfully separates the dispersed crowd sound, reflections, reverb
and atmosphere - offering the user adjustable parameters to position
this diffused sound as desired into 5.1 image.
UK's public service broadcaster has been working closely with TSL and
SoundField in the development of upmixing techniques and algorithms
to achieve a high quality and reliable process for use in live sport
programme mixing chains. SoundField allows the BBC to ensure that the
dialogue is clearly audible, and the mix is compatible for broadcast
throughout the various platforms and outlets that they offer.
