BBC inches closer to 3D audio broadcast
Engineers at British broadcaster, the BBC, are developing a technology based on ambisonics to deliver three-dimensional sound through radios and televisions. The psychoacoustic approach will make listeners feel that sound is coming from all around them and does not require replacement radios or TVs. The BBC first revealed its plans in a white paper that was published at the 128th Audio Engineering Society Convention in London in 2010.
Researchers Christopher Baume and Anthony Churnside explain that the development of ambisonics began in the 1970s but assert that low-cost digital processing and freely-available digital production tools makes it easier for broadcasters to utilise the technology.
The white paper points out that coining the term ‘3D sound’ could have a positive impact on BBC marketing activities which is evident out in this latest round of marketing activity.
