Abstract
L'invention divulgue un système (110) et un procédé de reproduction sonore. Le système (110) comprend une pluralité de haut-parleurs configurés pour générer un champ sonore dans une zone de reproduction sonore et un circuit de traitement configuré pour faire fonctionner les haut-parleurs sur la base d'un contenu audio d'entrée dans une pluralité de modes de reproduction sonore différents, comprenant un premier mode de reproduction sonore basé sur la réflexion ou un second mode de reproduction sonore basé sur un son direct. Le circuit de traitement est en outre configuré pour obtenir des informations concernant l'environnement acoustique du système (110) et pour déterminer, sur la base des informations, une mesure de performance du premier mode de reproduction sonore basé sur la réflexion. De plus, le circuit de traitement est configuré pour, sur la base de la mesure de performance, sélectionner ou recommander le premier mode de reproduction sonore basé sur la réflexion ou le second mode de reproduction sonore basé sur un son direct pour faire fonctionner les haut-parleurs. Ainsi, le système (110) peut sélectionner ou recommander le mode de reproduction sonore le plus approprié pour un environnement acoustique donné.
