Stereophonic broadcasting method for use in e.g. computer, involves transmitting additional signals along direction forming specific angle with primary direction, where one signal results from difference between left and right sound signals

摘要

The method involves transmitting left and right sound signals along a primary direction (4a). An additional signal resulting from a difference between the sound signals and another additional signal resulting from a phase inversion of the former additional signal are processed. The additional signals are transmitted along a secondary direction that forms an angle between 90 and 180 degrees with the former direction. An independent claim is also included for a stereophonic broadcasting device comprising a left main loudspeaker.
