Abstract

Un aparato para mejorar una señal de audio comprende un procesador de señales para procesar la señal de audio a fin de reducir o eliminar porciones transitorias y tonales de la señal procesada y un eliminador de correlación para generar una primera señal sin correlación y una segunda señal sin correlación de la señal procesada. El aparato comprende además un combinador para combinar de forma ponderada la primera y la segunda señal sin correlación y la señal de audio o una señal derivada de la señal de audio por mejora de coherencia utilizando factores de ponderación variantes en el tiempo y para obtener una señal de audio de dos canales. El aparato comprende además un controlador para controlar los factores de ponderación variantes en el tiempo al analizar la señal de audio de tal forma que se multiplican diferentes porciones de la señal de audio por diferentes factores de ponderación y la señal de audio de dos canales tiene un grado variante en el tiempo de eliminación de correlación.
