Abstract

L'invention concerne un procédé et un appareil de traitement électronique de signaux sonores. Un signal monophonique est divisé entre deux circuits dont l'un contient un dispositif produisant des harmoniques d'ordre inférieur avec un déphasage qui dépend de la fréquence et de l'amplitude, et un dispositif de reglage de l'amplitude par rapport à l'amplitude du signal dans l'autre circuit. Les signaux des deux circuits sont ensuite combinés, électroniquement ou acoustiquement. L'invention s'applique notamment à l'enregistrement, la reproduction, l'analyse et la transmission des sons.A method and apparatus for electronic processing of sound signals is disclosed. A monophonic signal is divided between two circuits, one of which contains a device producing lower order harmonics with a phase shift which depends on frequency and amplitude, and a device for adjusting the amplitude with respect to the signal amplitude in the other circuit. The signals from the two circuits are then combined, electronically or acoustically. The invention applies in particular to the recording, reproduction, analysis and transmission of sounds.
