Abstract

SE DESCRIBE UN SISTEMA DE PROCESAMIENTO ACUSTICO ESTEREOFONICO (20, 26, 24, 28) QUE TIENE CANALES ACUSTICOS ESTEREOFONICOS IZQUIERDO Y DERECHO CON RESPECTO A ALTAVOCES CORRESPONDIENTES. EL SISTEMA DISPONE DE EXPANSION ESPACIAL DEL SONIDO ESTEREOFONICO, CON LO QUE UN PRIMER PAR DE LOS ALTAVOCES (30) SEPARADOS DAN LA SENSACION DE ESTAR ESPACIADOS UNO DE OTRO MAS DE LO QUE REALMENTE LO ESTAN. EL SISTEMA ACUSTICO DISPONE DE MEDIOS (40) PARA CONECTAR UN SEGUNDO PAR DE ALTAVOCES, QUE PUEDEN SITUARSE ESPACIALMENTE A UNA DISTANCIA ENTRE LOS ALTAVOCES, QUE ES MAYOR QUE LA DEL PRIMER PAR DE ALTAVOVES. EL SISTEMA ACUSTICO DISPONE DE APARATOS PARA PROPORCIONAR SONIDO ESTEREO SIN EXPANSION ESPACIAL, CUANDO SE USAN TALES ALTAVOCES SECUNDARIOS.
