Abstract

L'invention porte sur un procédé de contrôle de tonalité d'un signal sonore, ledit signal sonore étant perçu à l'intérieur d'un volume d'écoute avec une intensité sonore caractérisée par un indice d'intensité sonore, ledit procédé de contrôle de tonalité comprenant l'application d'un banc de filtres audit signal sonore, ledit banc de filtres comprenant une pluralité de filtres configurés pour amplifier ou atténuer ledit signal sonore en fonction de réglages effectués par l'utilisateur. Selon l'invention, ledit procédé de contrôle de tonalité comprend par ailleurs l'application d'un gain de calibration à chacun des filtres du banc de filtres, chacun desdits gains étant configurés de telle sorte que l'indice d'intensité sonore du signal sonore perçu dans le volume d'écoute soit, en moyenne, constant.
