Abstract
La presente invencion se refiere a un metodo y dispositivo para procesar y reproducir una senal de audio estereo. El metodo produce una senal de salida izquierda para la transmision a un altavoz izquierdo en un par de altavoces, que es, o es equivalente a, la suma de la senal de entrada media (M) y la senal de entrada lateral (S), el metodo ademas produce una senal de salida derecha para la transmision a un altavoz derecho en el par, que es, o es equivalente a, la suma de la senal de entrada media (M) y la senal lateral (S) de fase cambiada a 180??. El metodo adicionalmente esta caracterizado en que por lo menos parte de la senal de entrada lateral (S) o la senal de entrada media (M) es la fase cambiada a aproximadamente 45??-135?? con relacion a la otra senal antes de o en la produccion de las senales de salida izquierda y derecha. La invencion adicionalmente se refiere a un sistema de reproduccion de senal de audio estereo.
