Abstract

La presente invención se refiere a sistemas y métodos que utilizan un algoritmo genético modificado para adaptar un sistema de audio estándar, tal como el de un televisor de gama alta, a una sala determinada u otra ubicación física que presente un entorno auditivo específico o único con un conjunto de propiedades acústicas. Un sistema de audio se adapta a una sala determinada mediante la determinación de una solución EQ con base en IIR a través de técnicas iterativas, incluida una técnica iterativa con base en un algoritmo genético adaptado para una solicitud de ecualización de la respuesta en frecuencia de audio. En una variante, un sistema de audio se adapta a una sala determinada, se ajusta el EQ a través del ancho de banda de un micrófono mientras se preserva la respuesta EQ calibrada de fábrica a través del ancho de banda restante.
