ABSTRACT:
A system for reproducing stereophonic sound signals to create an appropriate audio sound ambience in various compartments having different reverberation characteristics. The system includes a right-hand loudspeaker for producing a right-channel sound signal, left-hand loudspeaker for producing a left-channel sound signal, and a center loudspeaker for producing a signal derived from a combination of right and left signals. The center loudspeaker generates a sound output of a signal having a predetermined lag time relative to that of the right- and left-speakers to create the suitable audio ambience effect for a listener in accordance with the reverberation characteristics of the compartment.
