Abstract
Se da a conocer un aparato para decodificar una señal de audio codificada, en el cual una o más pistas están asociadas a la señal de audio codificada, donde cada una de las pistas tiene una pluralidad de posiciones de pista y una pluralidad de pulsos. El aparato comprende un decodificador de información de pulsos (110) y un decodificador de señales (120). El decodificador de información de pulsos (110) está adaptado para decodificar una pluralidad de posiciones de los pulsos, donde cada una de las posiciones de los pulsos indica una de las posiciones de pista de una de las pistas para indicar una posición de uno de los pulsos de la pista y donde el decodificador de información de pulsos está configurado para decodificar la pluralidad de posiciones de los pulsos utilizando un número de posiciones de pista que indica un número total de las posiciones de pista de por lo menos una de las pistas, un número total de pulsos que indica un número total de los pulsos de por lo menos una de las pistas y un número de estados. El decodificador de señales (120) está adaptado para decodificar la señal de audio codificada mediante la generación de una señal de audio sintetizada utilizando la pluralidad de posiciones de los pulsos y una pluralidad de coeficientes de filtro predictivos que están asociados a la señal de audio codificada.
