The Invention

Scheiber invented apparatus for communicating three or more directional sound signals on standard, two-channel audio systems.

Two position angles, alpha and beta, are assigned to each of the sound signals. By proper selection of position angles, a sound source can be located in three dimensions. Amplitude ratios and phase differences of sound signal components, coupled to the respective channels, define the alpha and beta angles for each sound signal. For encoding input sound signals f, having position angles alpha and beta (where A and B are the two channels), the equations are:

The equation for deriving decoded output signals g„ is:
