5.1 sound from a two-channel signal

A special focus on sports broadcasting is being spearheaded on Sennheiser’s stand by the Esfera surround sound system which creates a fully-fledged 5.1 sound from a two-channel signal.

According to Sennheiser, a production team can generate and broadcast 5.1 surround sound with Esfera using two standard audio cables. Mounted onto a camera or installed in a stadium, the compact Esfera microphone can be operated like any rugged stereo microphone. The sound can then be converted to 5.1 at any point in the workflow.

Anders Laybourn, marketing manager, Sennheiser Broadcast & Media, said, “The system is very much comparable to the human ears and brain. Esfera ‘hears’ through two microphones, and its separate processing unit turns the mic sound into a surround image, very much like our brain does with the sounds the ears pick up.”
