Abstract

Se describe un método para el procesamiento de una señal de audio (400) de acuerdo con una respuesta al impulso de la habitación (434). La señal de audio (400) se procesa por separado (422, 424) con una parte temprana y una reverberación tardía de la respuesta al impulso de la habitación (434), y la parte temprana procesada (428) de la señal de audio y la señal reverberada (430) se combinan (432). Una transición de la parte temprana a la reverberación tardía en la respuesta al impulso de la habitación se alcanza cuando una medida de correlación alcanza un umbral, el umbral se establece dependiendo de la medida de correlación para una seleccionada de las reflexiones tempranas en la parte temprana de la respuesta al impulso de la habitación.
