Engineers at the BBC are reported to be working on developing 3D radio. According to a report in The Telegraph, researchers at the BBC's technology unit, BBC R&D, have been developing acoustics that make a listener believe that they are actually present at events such as concerts with sound coming from every direction - even above and below.

The engineers claim that the new form of radio will enable listeners to receive 3D sound from their existing radio and television speakers.

According to the report, engineers have tested the new technology with recordings of the Last Night of the Proms, a concert by the rock band Elbow, and a radio play of the Wizard of Oz.

Anthony Churnside, who co-authored the BBC R&D research paper, said that there are a number of ways to create 3D sound like the psychoacoustic tricks that can make listeners perceive sound from above and below.

BBC engineers have been testing different technologies including ambisonics which includes recording the audio using microphones at different locations.

The soundtracks are broadcast simultaneously, with advanced hi-fi equipment and televisions decoding and configuring the signals according to each listener's speaker set-up.
