Abstract
La figura 1 ilustra un decodificador (100) para decodificar un cuadro actual para reconstruir una señal de audio de acuerdo con una modalidad. La señal de audio se codifica dentro del cuadro actual. El cuadro actual comprende una carga útil de flujo de bits actual. La carga útil de flujo de bits actual comprende una pluralidad de bits de carga útil. La pluralidad de bits de carga útil codifica una pluralidad de líneas espectrales de un espectro de la señal de audio. Cada uno de los bits de carga útil exhibe una posición dentro de la carga útil de flujo de bits actual. El decodificador (100) comprende un módulo de decodificación (110) y una interfaz de salida (120). El módulo de decodificación (110) se configura para reconstruir la señal de audio. La interfaz de salida (120) se configura para emitir la señal de audio. El módulo de decodificación (110) comprende un modo de ocultación de errores (110), en donde, si el módulo de decodificación (110) se encuentra en el modo de ocultación de errores, el módulo de decodificación se configura para reconstruir la señal de audio al llevar acabo ocultación de errores para aquellas líneas espectrales del espectro de la señal de audio, que exhiben una frecuencia que es mayor que una frecuencia umbral. Y/o, si el módulo de decodificación (110) lleva a cabo ocultación de errores, el módulo de decodificación (110) se configura para realizar ocultación de errores de una manera que depende de si o no una carga útil de flujo de bits anterior de un cuadro anterior que precede al cuadro actual codifica un componente de señal de la señal de audio que es tonal o armónico.
