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 en la codificación de audio de canales múltiples puede volverse más eficiente realizando el llenado de ruido basado en el ruido generado utilizando líneas espectrales de una trama previa de, o un canal diferente de la trama actual de, la señal de audio de canales múltiples.
