Conference Paper
Ambisonics-An Overview
AES Conference: 8th International Conference: The Sound of Audio · Paper 8-024 · May 1990
Abstract
Ambisonic Surround Sound has been with us for about fourteen years now and is regularly used by many Hi-Fi enthusiasts in their homes and some recording companies and broadcasters. The advent of stereo television and multichannel audio via satellite, cable and video systems, poses the question of the most effective use of 2, 3 or 4 related audio channels. The Ambisonic UHJ hierarchy for transmitting total sound fields offers more varied mutually compatible applications than other proposals (e.g. quadraphonics), with options up to and including the full sphere (-periphonic-) directional reproduction. These options are detailed, including mono, stereo, 2, 2-1/2, 3 and 4 channel horizontal surround encoding, 4-channel periphony, and a range of user sound field adjustments in stereo and psychoacoustically optimized surround-sound reproduction modes.
