Orchestrating Space by Icosahedral Loudspeaker (OSIL) by Gerriet K. Sharma

The project "Orchestrating Space by Icosahedral Loudspeaker" (OSIL) aimed at increasing the practical and theoretical understanding of electroacoustic sound phenomena that are defined by their sculptural-choreographic nature, i.e., exhibiting localization, motion, and extent. Such auditory objects are new means of expression and as such they have already been subject of artistic research in the project "The Choreography of Sounds" (CoS), PEEK AR 41. In particular, the project focused on the icosahedral loudspeaker (IKO) constructed at IEM in order to project auditory objects into rooms, a feature that has already been successfully employed in various sonic art works that have been performed in concerts and installations in different halls and listening situations. Within OSIL artists and scientists were working closely together trying to understand the field of 3D audio better with an multi-perspective approach to foster and extend aesthetical practices in this field.
