ABSTRACT:
A stereophonic sound system is disclosed, having a source of stereophonic signals which contain a right signal and a left signal as well as further signals which supplement the right and left signals to convey a three-dimensional sound impression. The right and left signals are adapted to a stereo base of a pair of loudspeakers having a correspondingly small size by means of a modification circuit. Of the stereophonic signals, only the right and left signals are fed to the modification circuit so that they are falsified as little as possible. An improved system for conveying a three-dimensional sound impression is thus provided.
