Abstract

Se proporciona un aparato para procesar una señal de audio que tiene asociada con el mismo una información de desfase de tono y una información de ganancia, que comprende un conversor de dominio (100) para convertir una primera representación de dominio de la señal de audio en una segunda representación de dominio de la señal de audio; y un filtro posterior de armónicos (104) para filtrar la segunda representación de dominio de la señal de audio, en la que el filtro posterior está basado en una función de transferencia que comprende un numerador y un denominador, en la que el numerador comprende un valor de ganancia indicado por la información de ganancia, y en la que el denominador comprende una parte entera de un desfase de tono indicado por la información de desfase de tono y un filtro de pulsaciones múltiples que depende de una parte fraccionaria del desfase de tono.
