Abstract

Un decodificador de audio (100; 300) para proveer una información de audio decodificada (112; 312) sobre la base de una información de audio codificada (110; 310) comprende un ocultamiento de error (130; 380; 500) configurado para proveer una información de audio de ocultamiento de error (132; 382; 512) para el ocultamiento de una pérdida de una trama de audio luego de una trama de audio codificada en una representación de dominio de frecuencia (322), usando una señal de excitación de dominio de tiempo (532).An audio decoder (100; 300) for providing decoded audio information (112; 312) based on encoded audio information (110; 310) comprises an error concealment (130; 380; 500) configured to provide an error concealment audio information (132; 382; 512) for concealment of a loss of an audio frame after an audio frame encoded in a frequency domain representation (322), using an excitation signal of time domain (532).
