Abstract

Un método y aparato de procesamiento de señales de audio para ajustar de forma adaptativa un descorrelacionador. El método comprende obtener un parámetro de control y calcular la media y la variación del parámetro de control. Se calcula la relación de la variación y la media del parámetro de control, y se calcula un parámetro de descorrelación en función de dicha relación. El parámetro de descorrelación se proporciona a un descorrelacionador.
