Abstract

Un aparato para generar una señal de ocultamiento de error comprende: un generador de representaciones de LPC (100) para generar una representación de LPC sustituta; un calculador de ganancias (600) para calcular una información de ganancia a partir de las representaciones de LPC; un compensador (406, 408) para compensar un efecto de ganancia de la representación de LPC sustituta empleando la información de ganancia y un sintetizador de LPC (106, 108) para filtrar información de libro de códigos empleando la representación de LPC sustituta para obtener la señal de ocultamiento de error, donde el compensador (406, 408, 900) está configurado para ponderar la información de libro de códigos o una señal de salida de síntesis de LPC.
