Abstract

En la codificación de audio de canales múltiples, se logra una mejor eficiencia en la codificación tomando la siguiente medida: el llenado de ruido de bandas de factor de escala con cuantificación cero se realiza utilizando el llenado de fuentes de ruido en vez de ruido generado en forma artificial o réplicas espectrales. En particular, la eficiencia de la codificación eficiencia en la codificación de audio de canales múltiples podrá ser aun mayor realizando el llenado de ruido basado en el ruido generado utilizando líneas espectrales de un cuadro previo de, o un canal diferente del cuadro actual de, la señal de audio de canales múltiples.
