Ambisonics is a full-sphere surround sound format created by a group of English researchers — among them Michael A. Gerzon, Peter Barnes Fellgett, and John Stuart Wright — under support of the National Research Development Corporation (NRDC) of the United Kingdom. In addition to the horizontal plane, the format incorporates sound sources above and below the listener. The term is used as both a generic name and formerly as a trademark.
