Abstract

La présente invention concerne les dispositifs de traitement d'un son original défini sur une bande passante de fréquences allant des basses fréquences aux hautes fréquences, pour lui donner plus de relief. Le dispositif comporte des moyens 10 aptes à capter le son original, ces moyens étant aptes à délivrer, sur leur sortie 11, un premier signal représentatif du son original capté ; des moyens 20 pour traiter le premier signal pour amplifier sa partie correspondant aux basses fréquences et à délivrer, sur leur sortie 21, un deuxième signal électrique comprenant le premier signal dans lequel la partie correspondant aux basses fréquences a été amplifiée par rapport aux autres fréquences ; des moyens 30 pour traiter le deuxième signal pour générer des harmoniques pairs et délivrer, sur leur sortie 31, un troisième signal comprenant le deuxième signal et ces harmoniques pairs ; des quatrièmes moyens 40 pour traiter le troisième signal pour générer des harmoniques impairs et délivrer, sur leur sortie 41, un quatrième signal comprenant le troisième signal et les harmoniques impairs ; et des moyens 50 aptes à recevoir, sur leur entrée 51, le quatrième signal et à délivrer, sur leur sortie 52, le son traité final.
