M.S.S.S. stands for: Modular Spatial Sound Systems. The basic goal of M.S.S.S. is to develop modular structures by which speakers can be placed in space in order to create a spatial sound environment. With the structures it becomes much easier to compose sound-movement in space. By making the structures modular it also becomes possible to fill different spaces with the same sound-movement structure. The video’s here are showing filmed models or already realised installations based on this idea.
