IKO/OSIL Symposium & Summer School Sept. 10th - 14th 2018 Graz

The IKO/OSIL summer school and symposium was held on Sept. 10th to 14th 2018 and finalized our compact spherical loudspeaker array research from the past 4 years:

Orchestrating Space by Icosahedral Loudspeaker (OSIL).

The 2-day symposium offered the opportunity to learn about our artistic, psycho-acoustic, and audio-technical experiences and findings.

The 3-day summer school that preceded the symposium allowed registered visitors to work and experiment with the 3 IEM Icosahedral Loudspeakers (IKO). Its working spaces are Ligeti Hall, Studio Stage Room, Orchestra Rehearsal Room, and the dressrooms at MUMUTH. There were the IKO1, IKO2, IKO3, and our new loudspeaker cubes to work and play with.

We were happy to host you Graz!

The OSIL team.
