Edwin van der Heide, A World Beyond the Loudspeaker, 2005

The installation consists of a surface of 40 individual loudspeakers. The use of this number of loudspeakers with a relatively small spacing creates the possibility to not only ‘simply’ create vibrations in the air but also to control the spatial shape of the produced waves. Together the loudspeakers form one large spatial wave field synthesizer. Sound production based on wave field synthesis forms the basis for a realistic spatial experience different from other multi speaker setups. To record the sound material for the installation, an identical surface of 40 microphones was used. This surface has the same qualities as the loudspeaker surface; The grid of microphones is able to record the spatial propagation of the sound waves in the air. The playback of the final composition happens from a 40 channel multitrack system.
