Abstract

Los sistemas y métodos 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 y particular o a otra zona física que presente un entorno auditivo especifico o único con un conjunto de propiedades acústicas. Un sistema de audio se adapta a una sala determinada mediante la determinación de una solución de ecualizador (EQ) con base en una respuesta al impulso infinita (IIR) a través de técnicas iterativas, incluida una técnica iterativa con base en un algoritmo genérico adaptado para una aplicación 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 de ecualización calibrada de fábrica a través del ancho de banda restante.
