Scaling new heights in broadcasting using ambisonics


Chris Baume and Anthony Churnside


As the world's biggest broadcaster, the BBC transmits over 400 hours of audio content every day; the vast majority of which is in stereo. This paper will look at why the BBC is interested in Ambisonics, and describe recent experiences in trying out the technology in its first-order format. Two subjective listening tests are described, which attempt to discover how Ambisonics compares to current technology, and how much the height dimension contributes towards the listening experience.
