Abstract
La presente invención se refiere a un método de reproducción de una señal de audio de canales múltiples que incluye una señal de sonido de elevación en un ambiente de disposición horizontal, mediante el cual se obtiene un parámetro de emisión de acuerdo a un tipo de emisión y se configura a una matriz de mezcla descendente, y de este modo el funcionamiento de emisión efectivo puede ser obtenido con respecto a una señal de audio que no es adecuada para aplicar la emisión virtual. Un método de emisión de una señal de audio incluye la recepción de una señal de canales múltiples que comprende una pluralidad de canales de entrada que van a ser convertidos a una pluralidad de canales de salida; determinar un tipo de emisión para la emisión de elevación, con base en un parámetro determinado a partir de una característica de la señal de canales múltiples; y la emisión de al menos un canal de entrada de altura de acuerdo al tipo de emisión determinado, en donde el parámetro es incluido en una corriente de bitios de la señal de canales múltiples.
