Grain Room

Sound Design / Interactive Installation | 2012


Grain Room is an interactive audio installation for particle based granular sounds. Particle, meaning a moving unit of sound, have a will of their own and they can freely move around the room. The particles enter the space whenever somebody opens the sliding doors leading outside, and the particles leave the space whenever the doors leading inside to the lobby are opened. When the doors remain closed the particles can be trapped inside the room (if all the particles have not flown out of the room).

The first version of Grain Room was demonstrated in the Cumulus Helsinki 2012 Conference: Northern Wold Mandate with randomly generated nature sounds (birds and insects) in a 6 channel environment.
