Story in Sunday's Telegraph:
"Three-dimensional television may only just have arrived, but engineers at the BBC are already working on the next step - 3D radio.
Researchers at the corporation's technology unit, BBC R&D, have been developing acoustics that can trick the listener into believing they are really at events such as concerts with sound coming from every direction - even above and below."
The article includes links to BBC Research and Development White Paper 221, Upping the Auntie - a broadcasters take on ambisonics, published in March and a spoof Radio 4 Today item, Does 3D Radio work, broadcast on April 1 last year.
