ABSTRACT:
In a sound reproduction system of the type which enables the listener to distinguish sound from sources extending over 360.degree. of azimuth, compensation is provided for the asymmetry arising when four loudspeakers are located at the corners of a non-square rectangle. Compensation is also provided for the different localization mechanisms used by a human listener at high and low frequencies. The invention is also applicable to systems which enable the listener to distinguish sounds from different heights.
