French composer (27 April 1932, Tamatave, Madagascar). Studied in Bordeaux (1946–54), at the Paris Conservatoire, with Olivier Messiaen (1958–9) and at the Darmstadt summer courses (1960–62) with Karlheinz Stockhausen, among others. Joined the Service de la recherche of Organisation de la radio télévision Française (ORTF) in 1960, recently established by Pierre Schaeffer.
In 1966 Schaeffer put Bayle in charge of the Groupe de recherches musicales (GRM). From then on he remained active as a composer, an administrator and a music theorist. During these years he organized concerts, radio broadcasts, seminars and events celebrating individual composers, supported technological developments (Syter, GRM Tools, Midi Formers, Acousmographe) and was behind major innovations, such as the Acousmonium (an orchestra of loudspeakers) and the INA-GRM recordings label. He also founded in 1992 the Acousmathèque with a repertory of 2000 works composed after 1948.
After leaving GRM in 1997, he founded his own audio-numerical and multiphonic studio, the Studio Magison, where he has devoted himself to research, writing and composition.
