Abstract
Se proporciona un método y un sistema correspondiente para la determinación de filtros de ajuste de fase para un sistema de generación de sonido asociado que comprende al menos dos canales de reproducción de audio C1 y C2, en donde cada uno de tales canales de reproducción de audio C1 y C2 tiene una señal de entrada y al menos un altavoz situado en un entorno del escucha. El método comprende la estimación de (S1), para cada uno de tales canales de reproducción de audio de C1 y C2, una función de transferencia acústica en cada uno de M= 1 posiciones espaciales en dicho entorno de audición, basados en mediciones de sonido en tales posiciones espaciales; y determinar (S2), en base a dicho funciones de transferencia acústica, ajuste de fase filtros F1 () y F2 () a aplicar, respectivamente, a tales canales de reproducción de audio C1 y C2, para reducir el diferencial de fase inter-altavoz, IDP, entre tales canales de reproducción de audio de C1 y C2en las posiciones del escucha p. (Figura 16).
