Abstract
La invención se refiere a un aparato de procesamiento de señal de audio (100) para filtrar una señal de audio de entrada de canal izquierdo (L) y una señal de audio de entrada de canal derecho (R), una señal de audio de salida de canal izquierdo (X1) y una señal de audio de salida de canal derecho (X2) que se van a transmitir a través de rutas de propagación acústica hasta un oyente, en donde se definen las funciones de transferencia de las rutas de propagación acústica por una matriz de función de transferencia acústica. El aparato de procesamiento de señal de audio (100) comprende un descomponedor (101), un primer reductor de diafonía (103), un segundo reductor de diafonía (105), y un combinador (107). Se configura el primer reductor de diafonía (103) para reducir una diafonía dentro de una primera banda de frecuencia predeterminada con base en la matriz de función de transferencia acústica. Se configura el segundo reductor de diafonía (105) para reducir una diafonía dentro de una segunda banda de frecuencia predeterminada con base en la matriz de función de transferencia acústica.
