Abstract
"MéTODO E DISPOSITIVO PARA PROCESSAR UM SINAL ESTéREO DE áUDIO DE ENTRADA, E, SISTEMA DE REPRODUçãO DE SINAL ESTéREO DE áUDIO". A presente invenção relaciona-se a métodos e dispositivos para processar um ou o outro de dois tipos de sinais estéreo de áudio de entrada comum, de forma que os sinais de saída reproduzirão normalmente som estéreo amplo de um sistema de reprodução estéreo de áudio que compreende um par de alto-falantes idênticos posicionados adjacentes ou perto um do outro. Assim, a invenção relaciona-se parcialmente a um método e um dispositivo para produzir aquele par específico de sinais de saída esquerdo e direito de um tipo (M + S) de sinais de entrada, e parcialmente a um método e um dispositivo para produzirem um tipo semelhante de sinais de saída esquerdo e direito de outro tipo (L + R) de sinais de entrada. Finalmente, a invenção relaciona-se a um sistema de reprodução de sinal estéreo de áudio que compreende um par de alto-falantes idênticos posicionados adjacentes ou perto um do outro e pretendidos para reprodução de som estéreo normalmente amplo de um (M + S) de ditos tipos de sinais de entrada.
