Abstract

L'invention a pour objet des procédés et dispositifs pour synthétiser des sons. Un synthétiseur selon l'invention comporte un premier oscillateur 01 qui émet un signal S1 de fréquence f1 dont l'amplitude peut être modulée, un amplificateur non linéaire A1 qui émet un signal distordu contenant les harmoniques k1f1, un deuxième oscillateur 02 qui émet un signal S2 de fréquence f2, dont l'amplitude peut être modulée, un deuxième amplificateur non linéaire A2 qui émet un signal distordu contenant les harmoniques k2f2, un circuit multiplicateur analogique XI qui multiplie les amplitudes des signaux distordus k1f1 et k1f2 et qui émet un signal S2 et un haut-parleur T qui émet un son contenant les fréquences k2f2 +- k1f1. Une application est la synthèse des sons harmoniques ou inharmoniques ayant des spectres complexes.
