Abstract
Un aparato de correccion acustica procesa un par de señales de entrada izquierda y derecha para compensar la distorsion especial como una funcion de frecuencia cuando las señales de entrada son reproducidas a través de altavoces en un sistema de sonido. La energía acustica de las señales de entrada izquierda y derecha es separada y corregida en una primera gama de baja frecuencia y una segunda gama de alta frecuencia. Las señales resultantes son recombinadas para crear señales de audio de imagen corregida teniendo una respuesta de presion acustica deseada cuando se reproducen por los altavoces en el sistema de sonido. La respuesta de presion acustica deseada crea un lugar de imagen de sonido aparente pueden ser entonces espacialmente mejoradas para ampliar la imagen de sonido aparente.
