Abstract

La invención se refiere a un aparato de procesamiento de señal (100) para mejorar un componente de voz dentro de una señal de audio multi-canal, la señal de audio multi-canal comprende una señal de audio de canal izquierdo (L), una señal de audio de canal central (C) y una señal de audio de canal derecho (R); el aparato de procesamiento de señal (100) comprende un filtro (101) y un combinador (103); en donde el filtro (101) está configurado para determinar una medición que representa una magnitud general de la señal de audio multi-canal sobre frecuencia sobre la base de la señal de audio de canal izquierdo (L), la señal de audio de canal central (C), y la señal de audio de canal derecho (R), obtener una función de ganancia (G) con base en una relación entre una medición de magnitud de la señal de audio de canal central (C) y la medición que representa la magnitud general de la señal de audio multi-canal, y ponderar la señal de audio de canal izquierdo (L) por la función de ganancia (G) para obtener una señal de audio de canal izquierdo ponderada (LE), ponderar la señal de audio de canal central (C) por la función de ganancia (G) para obtener una señal de audio de canal central ponderada (CE), y para ponderar la señal de audio de canal derecho (R) por la función de ganancia (G) para obtener una señal de audio de canal derecho ponderada (RE); y en donde el combinador (103) está configurado para combinar la señal de audio de canal izquierdo (L) con la señal de audio de canal izquierdo ponderada (LE) para obtener una señal de audio de canal izquierdo combinada (LEV), combinar la señal de audio de canal central (C) con la señal de audio de canal central ponderada (CE) para obtener una señal de audio de canal central combinada (CEV), y combinar la señal de audio de canal derecho (R) con la señal de audio de canal derecho ponderada (RE) para obtener una señal de audio de canal derecho combinada (REV).
