Virtual Sources is a musical composition that deals with the use of directional sound in live performance. Directional speakers radiate a beam of sound in one direction only. The speakers are used indirectly so the sound is heard only through reflections – by letting the sound bounce of walls, ceiling or any other surfaces before it is heard. When the sound is projected through dynamic or moving speakers with focus, some very unusual acoustic effects are created. The reflections of dynamic sound beams, seem as virtual source of sound moving all over the walls and ceiling. Directional sound, within the context of electro-acoustic composition, enables the exploration of new spatial-acoustic dimensions and the creation of dynamic and virtual fields of sound. The co-producers of the project are the Institute for Sonic Arts Research (IRZU) and the start-up company Ultrasonic audio technologies, which has been developing the technology of directional sound system for many years.
Bio
Miha Ciglar (1980) is an inter-media artist and researcher in the field of audio technologies. In 2009 he obtained his MSc degree at the University of Music and Performing Arts and the University of Technology in Graz (Austria). In 2008 he founded the Institute for Sonic Arts Research (IRZU). It is based on an interdisciplinary concept and is conducting artistic production in the field of electro-acoustic music/ inter-media performances and installations, as well as audio technology research and educational activities. Ciglar is the main initiator and curator of the International Sonic Arts festival EarZoom which takes place since 2009 within activities by IRZU. In 2011 he founded a start-up company named Ultrasonic Audio Technologies in order to commercialize technologies that are being developed at the Institute IRZU. In 2012, on the initiative of organization ICMA (International Computer Music Association), he organized the 38th International Computer Music Conference, which took place during the Festival EarZoom in Ljubljana.
