Abstract
Un codificador multiseñal para codificar por lo menos tres señales de audio, comprende: un preprocesador de señales (100) para preprocesar en forma individual cada señal de audio para obtener por lo menos tres señales de audio preprocesadas, donde el preprocesamiento es ejecutado de tal manera que una señal de audio preprocesada se blanquee con respecto a la señal con anterioridad al preprocesamiento; un procesador conjunto adaptativo de señales (200) para ejecutar un procesamiento de dichas por lo menos tres señales de audio preprocesadas para obtener por lo menos tres señales procesadas conjuntamente o por lo menos dos señales procesadas conjuntamente y una señal sin procesar; un codificador de señales (300) para codificar cada señal para obtener una o más señales codificadas; y una interfaz de salida (400) para transmitir o almacenar una señal de audio multiseñal codificada que comprende dichas una o más señales codificadas, información lateral con respecto al preprocesamiento e información lateral relacionada con el procesamiento.
