Abstract

Un método particular incluye codificar una primera trama de una señal de audio utilizando un primer codificador; el método también incluye generar, durante la codificación de la primera trama, una señal de banda base que incluye contenido correspondiente a una porción de banda alta de la señal de audio; el método además incluye codificar una segunda trama de la señal de audio utilizando un segundo codificador, donde la codificación de la segunda trama incluye procesar la señal de banda base para generar parámetros de banda alta asociados con la segunda trama.
