Abstract
Se describe un método para procesar una señal de audio (504) de acuerdo con una respuesta de impulso a ambiente. La señal de audio (504) se procesa (502) con una parte temprana de la respuesta de impulso a ambiente separada de una reverberación tardía de la respuesta de impulso a ambiente, donde el procesamiento (514) de la reverberación tardía comprende la generación de una señal reverberada escalada, donde la escalada (526) depende de la señal de audio (504). La parte temprana procesada (506) de la señal de audio (504) y la señal reverberada escalada están combinadas.
