the space, the place
I have long used the term "acousmonef"
to describe what a loudspeakers projection means
to me : a journey into sound space, with the speakers system
as a vessel. But it was only an idea, a way of describing
what is different from a traditional live-music concert.
With 130 m² on nearly 6 m height, the place offers a volume quite capable to allow the composition of spatially complex and exciting works. Without becoming the kind "acousmatic theater" that some have dreamed for decades (I'm part of it ...), its equipment can also support meetings, workshops and courses, may help composers to test or finalize their work, and also, from time to time, to organize sound projection sessions, where one can hear "alive sound", in all its dimensions.
Obviously, doing this in a village in Puy-de-Dôme may have some drawbacks as to its potential attendance... But the region is so beautiful !
the sound projection system
This place is dedicated mainly to the creation of loudspeaker soundworks (multichannel acousmatic) that integrate and use the space as a full element of their composition. This approach is partly derived from the history of musique concrète, such as "invented" by Pierre Schaeffer in 1948, and relies on more than thirty years of experimentation, reflection and almost daily composition.
For this, the Acousmonef uses a 62 independent channels fixed speakers arrangement, and the place can also be filled with the more original systems of the Acousmobile.
The design of this projection space has a long history, started with my first multiphonic works at the end of the 80s, and that can be summarized as follows : what speaker configuration can I set to be compatible with the existing standards (ie today 3D cinema audio formats as well as the multimedia/VR dome), and at the same time that can be sufficiently rich and flexible to meet my requirements and the relative diversity of my compositions ?
From the simple 3D structure that I have defined in the early 90's (see the installation Formes et couleurs de la vie), I have gone progressively to a "high resolution" solution where the outer part (45 channels on four levels) is common to all formats, and the inner part (18 channels on two levels) can be quickly adapted for the ring/double-dome, the pseudo-sphere and the extended cinema, or even put aside for the dome.

ring or double-dome (59.3 channels), and also the pseudo-sphere
(54.3 channels, without the 5 center blue ones) :
extended cinema (51.3 channels), NHK 22.2 and Auro-3D compatible + potentially Dolby Atmos and
DTS:X, with a proscenium and a far level.
dome (45.3 channels), compatible with 7th order HOA (see also the pseudo-sphere
