Abstract

Se describe un aparato (100) para adaptar una señal de audio espacial (2) para un equipo de altavoz original a un equipo de altavoz de reproducción que difiere del equipo de altavoz original. El aparato comprende un descomponedor de ambiente directo (130) que está configurado para descomponer las señales de canal en un segmento del equipo de altavoz original en sonido directo (D) y componentes ambientales (A), y para determinar una dirección de llegada de los componentes de sonido directo. Un suministrador de sonido directo (150) recibe una información del equipo de altavoz de reproducción y ajusta los componentes de sonido directo (D) utilizando la información del equipo de altavoz de reproducción, de modo que una dirección percibida de llegada de los componentes de sonido directo en el equipo de altavoz de reproducción es sustancialmente idéntica a la dirección de llegada de los componentes de sonido directo. Un combinador (180) combina los componentes de sonido directo ajustados y posiblemente los componentes ambientales modificados, para obtener las señales de altavoz para los altavoces del equipo de altavoz de reproducción.
