Abstract

Un aparato para generar una señal de ocultamiento de error, comprende: un generador de representaciones de LPC (100) para generar a representación de LPC sustituta; un sintetizador de LPC (106, 108) para filtrar una información del libro de códigos utilizando la representación de LPC sustituta; y un estimador de ruido (206) para estimar un cálculo de ruido durante la recepción de tramas de audio correctas, donde la estimación de ruido se basa en el generador de representaciones de tramas de audio correctas (100) que está configurado para usar la estimación de ruido estimada por el estimador de ruido (206) al generar la representación de LPC sustituta.
