A Geometric Model for Two-Channel Four-Speaker Matrix Stereo System

Document Thumbnail

Some of the properties of a convenient geometric model are described which is variously known as the -energy sphere,- -Stokes' sphere,- -Poincaré sphere,- or -representation sphere,- for describing two-channel information systems, such as matrix four-speaker systems. Several of its uses are outlined, including the study of directional ambiguities, compatibility, the behavior of variable matrix systems, the invention of systems, and stereo imaging. Once the relationship between the sphere and more direct representation of two-channel systems is established, it proves to be possible to survey the system's properties with virtually no need for mathematical formulas.
