Acousmonium, aka The Loudspeakers Orchestra, was invented in 1974 by French composer François Bayle driven by his researcher’s intention to give experimental electronic music, then young, a strong performance tool comparable to Orchestra of instrumental music.

Since then, with a few modifications, it has proven to be the standard for spatial interpretation of electroacoustic music. Acousmonium consists of 40-60 loudspeakers that vary in their frequency response, size and position in space among and around the audience, and the diffusion console. This composition is designed to set proper parameters for the sound field, that performer – projectionist – creates by playing.


Considered as a pioneering unit in electroacoustic, acousmatic and concrete music, the GRM (Music Research Group) has been, since 1958, a unique laboratory for sonorous experimentations.

Integrated with the INA (National Audiovisual Institute) since 1975, the GRM has kept a strong involvement in the experimental music field and is still expanding its repertoire every year.

Today, INA GRM welcomes internationally renowned composers in residency, produces concerts in France and abroad (PRÉSENCES électronique Festival, Multiphonies concerts season), and develops internationally acclaimed software for music production and sound design.

It conveys, to a broad audience, a cultural patrimony in constant evolution through radio shows on France Musique (L’Expérimentale), record production (monographic CD box-sets, Re-collection GRM), publications (Portraits polychromes, SPECTRES), and educational content (Creamus, Éduthèque).
