Abstract
Un decodificador de audio (200; 400) para proveer una información de audio decodificada (220; 412) sobre la base de una información de audio codificada (210; 410). El decodificador de audio comprende un ocultamiento de error (240; 480; 600) configurado para proveer una información de audio de ocultamiento de error (242; 482; 612) para el ocultamiento de una pérdida de una trama de audio, donde el ocultamiento de error está configurado para modificar una señal de excitación de dominio de tiempo (452, 456; 610) obtenida para una o más tramas de audio que preceden una trama de audio perdida, a fin de obtener la información de audio de ocultamiento de error.An audio decoder (200; 400) for providing decoded audio information (220; 412) based on encoded audio information (210; 410). The audio decoder comprises an error concealment (240; 480; 600) configured to provide error concealment audio information (242; 482; 612) for concealment of a loss of an audio frame, where concealment of Error is configured to modify a time domain excitation signal (452, 456; 610) obtained for one or more audio frames that precede a lost audio frame, in order to obtain the audio information of error concealment.
