After studying literature and music he began to work for the ORTF (French Radio and Television Organisation) Service de La recherche as assistant to Pierre Schaeffer in 1970. He was a member of the Groupe de Recherches Musicales (GRM) between 1971 and 1976.
His compositions elaborate on Schaeffarian theories and methodologies which Schaeffer referred to as musique concrète.

In particular, the book titled "L’audio-vision. Son et image au cinéma", originally published in France in 1990,
