Asterisms is a form of participatory concert, without a traditional frontal stage, making it possible to develop the active listening of the public by placing them at the center of the experience. The project is based on a distributed sound diffusion in the space with a large number of speakers (Raspberry Pi based system, participants' phones, and other). The participants can be mobile or not, as they choose, to expand their listening experience within the space. Each member of the audience is unique while being part of a large movement, like stars connected in constellations. We create a common space that is both immersive and expansive.

Asterismes is currently in residency in artistic research at Ircam. On the occasion of the forum, we propose to the participants to take part in an experiment with their smartphones.
