Marlow, UK (August 21, 2015)—FOX Sports has chosen TSL Systems' SoundField X-1 upmix/downmix processor and a Soundfield UPM-1 stereo-to-5.1 upmixer as part of its audio production process.

FOX Sports first employed TSL Systems during its coverage of the FIFA Women’s World Cup 2015. This equipment has also been installed on Game Creek Video’s Encore remote truck and is being used to enhance FOX Sports’ golf and NFL broadcasts.

“The various audio elements that contribute to a sports program, from studio and location dialogue, to commentary, music, and crowd atmosphere typically come into us from a wide variety of mono, stereo and 5.1 sources,” explains FOX Sports’ Emmy Award-winning audio mixer Fred Aldous, who has been a broadcast audio consultant and mixer for over 30 years. "As the sound supervisor, it is my job to mix a show that immerses viewers in the surround sound atmosphere of the event while maintaining clear, consistent imaging of dialogue, and ambient sound.”

The UPM-1 uses an algorithm to perform detailed real-time analysis of the stereo source material, identifying and separating the ambience from the direct sound. Mono sources (dialogue, commentary, etc.) are extracted from the stereo signal and fed to the center channel and a frontal stereo image is maintained by keeping the direct sound sources at the front. The UPM-1 then feeds the extracted natural ambience to the rear surround channels.

"At FOX Sports, the edict is that all of the dialogue stays in the center channel only. However, with conventional upmixers, all sorts of content ends up going into that center channel, which dilutes my dialogue/announcer channel. With the UPM-1 I can use the divergence control to either allow content to be steered to the center channel completely, or to take it out and move it to left, right, left surround and right surround channels," says Aldous.
