BBC Radio is launching an experiment that will offer surround sound through standard headphones.
From tomorrow, a Christmas service from the BBC archives will be available online in a ‘binaural’ format that creates realistic immersive (or ‘surround’) sound through ordinary headphones.
The Radio 3 website will offer a recording of the 'Festival of Nine Lessons and Carols' from 2007 in binaural sound until the end of the Christmas period.
"This is part of an exciting series of trials such as HD Sound, and personal control of crowd versus commentary audio during events such as Wimbledon.”
Rupert Brun, Head of Technology BBC Audio & Music, adds: “This experiment is an attempt to enhance the standard ‘stereo’ sound headphone users have had for over 50 years and, although it is only a trial at this stage, if listener feedback is positive it could offer a significant improvement to audio quality in the future.”
At the same time, both the 2007 recording and a pioneering experimental stereo recording of 'Nine Lessons and Carols' from 1958 will be available in a surround sound format suitable for conventional loudspeakers, such as those used as part of a home cinema system.
The 1958 stereo recording has been converted to surround sound using technology from Fraunhofer IIS in Germany.
The pieces were chosen as King's College Cambridge – where the recordings took place – has a rich, reverberant acoustic and the location of choir, organ and congregation offers good opportunities for surround sound.
The trial is part of BBC Radio’s continuing innovation in audio, including the launch of HD Sound, the Wimbledon NetMix experiment and ongoing trials of ‘3D Sound’ technology.
This year’s ‘Festival of Nine Lessons and Carols’ will be broadcast live on Radio 4 on Christmas Eve and will also be available online in HD Sound.
