Abstract

Se describe un aparato de codificación de audio que comprende un codificador para codificar un segmento de tiempo de una señal de audio de entrada a ser codificado para obtener un segmento de señal codificada correspondiente. El aparato de codificación de audio comprende además un descodificador para descodificar el segmento de señal codificado para obtener un segmento de señal re-descodificado. Se provee un detector de recorte para analizar el segmento de señal re-descodificado con respecto a por lo menos uno de un recorte de señal real o un recorte de señal perceptible y para generar una alerta de recorte correspondiente. El codificador está configurado además para codificar otra vez el segmento de tiempo de la señal de audio con por lo menos un parámetro de codificación modificado dando como resultado una probabilidad de recorte reducida en respuesta a la alerta de recorte.
