Realtime Sound Spatialization with Wave Field Synthesis. Workshop in Barcelona 18-20/6 2012
Two of the core members of The Game of Life’s Foundation team will impart a 3-day seminar on realtime sound spatialization with wave field synthesis. The seminar will deal with both compositional and technical issues surrounding spatial music and, focusing on electroacustic composition for wave field synthesis systems. The Game Of Life Foundation‘s mobile wave field synthesis system (composed of 192 speakers and 12 subwoofers) will be available on-site for participants to learn to operate the system and gain hands-on familiarity with space as a compositional parameter.
Wave field synthesis is a technique for sound spatialisation. It produces “artificial” wave fronts synthesized by a large number of individually driven speakers. Such wave fronts seem to originate from a virtual starting point. Contrary to traditional spatialization techniques such as stereo, the localization of virtual sources in WFS does not depend on or change with the listener’s position. As opposed to most multichannel systems, WFS has no sweet spot and allows for a wider optimal listening area.

Tutors: Arthur Sauer and Wouter Snoei.
Arthur Sauer is a composer and performer. He has been writing electronic music, instrumental music, music for film, dance, theatre etc. He has been experimenting with spatial music for quite some time, which resulted in
founding The Game of Life Foundation. With this foundation he took the initiative to build a Wave Field Synthesis System. With Hotel Modern he created the concept op Live Animation Movies. He’s been touring all over the world.
Wouter Snoei studied at the Institute of Sonology in The Hague. He has worked in various fields of music practice, all involving electronic music. He has directed several performances of electroacoustic pieces by Luigi Nono, John Cage and Gérard Grisey. He works regularly with Slagwerkgroep Den Haag, ASKO Kamerkoor and VocalLab. Wouter also performed with Jasper Blom and other jazz artists at the North Sea Jazz festival, and as a dance producer in many Dutch club venues. In the past few years Wouters focus has shifted more and more towards composition and performance of solo live electronics and electro-acoustic music, adding live control as part of electronic composition. Furthermore Wouter is involved as composer and developer of Wave Field Synthesis, a spatial sound system involving 192 loudspeakers placed around an audience, and as a teacher at the Utrecht School of Arts and the Royal Conservatoire of The Hague.
