Abstract

Un método para el procesamiento de señal,que comprende: (a) recibir una entrada de señal dispuesta u organizada en tramas o cuadros, comprendiendo un cuadro respectivo la información de audio codificada destinada a múltiples canales de audio (102a, 102b), (b) recibir múltiples señales de control (103a, 103b), estando asociada cada señal de control a uno respectivo de dichos múltiples canales de audio, (c) generar, en respuesta a dichas señales de control para un cuadro respectivo de dicha señal de entrada, grupos de palabras de control de ganancia tales que cada grupo de palabras de control de ganancia esté asociado con uno respectivo de dichos canales de audio, y un grupo respectivo de palabras de control de ganancia represente los niveles de comienzo y de final para la reproducción de una señal de audio generada para el canal de audio asociado a partir de la información de audio codificada comprendida en dicho respectivo cuadro, y (d) generar una señal de salida dispuesta en cuadros, comprendiendo un cuadro respectivo dicha información de audio codificada para dichos múltiples canales de audio y los grupos asociados de palabras de control de ganancia, donde dicha señal de salida presenta una forma adecuada para la transmisión o el almacenamiento.
