Abstract

Se proporciona un aparato para decodificar una señal de audio codificada para obtener una señal de audio reconstruida. El aparato comprende una interfaz receptora (1310) para recibir una pluralidad de tramas, un búfer de retardo (1020; 1320) para almacenar muestras de señales de audio de la señal de audio codificada, un selector de muestra (1030; 1330) para seleccionar una pluralidad de muestras de señales de audio seleccionadas de las muestras de señales de audio que están almacenadas en el búfer de retardo (1020; 1320), y un procesador de muestras (1040; 1340) para procesar las muestras de señales de audio seleccionadas para obtener muestras de señales de audio reconstruidas de la señal de audio reconstruida. El selector de muestras (1030; 1330) se configura para seleccionar, si una trama actual se recibe por la interfaz receptora (1310) y si la trama actual que se recibe por la interfaz receptora (1310) no está alterada, la pluralidad de muestras de señales de audio seleccionadas de las muestras de señales de audio que son almacenadas en el búfer de retardo (1020; 1320) dependiendo de una información de retraso de altura que está comprendida por la trama actual. Además el selector de muestras (1030;1330) se configura para seleccionar, si la trama actual no se recibe por la interfaz receptora (1310) o si la trama actual que se recibe por la interfaz receptora (1310) está alterada, la pluralidad de muestras de señales de audio seleccionadas de las muestras de señales de audio que están almacenadas en el búfer de retardo (1020; 1320) dependiendo de una información de retraso de altura que está comprendida por otra trama que se recibió previamente por la interfaz receptora (1310).
