The experience will only work if you listen with headphones, and in a quiet location. Closing your eyes helps. Relax and let yourself naturally build a mental picture of your surroundings based only on what you hear.
ABOUT 4D SOUND
The 4D Sound System was designed and developed in Amsterdam by Paul Oomen, Salvador Breed, Luc Van Weelden and Poul Holleman. It comprises 16 columns with omnidirectional speakers at several heights in each column, and the columns spaced around the room in a 12 x 12 x 4m array.
They have designed Max for Live devices which provide a range of spatial controls within Ableton Live, as well as an accompanying visual 3D model of the space and sounds within it. This allows for a spatial composition/production process, whereby each piece of music is designed as a physical entity to exist within the space, as something that can be walked around inside and explored by the listeners.
The system is called "4D Sound" because it produces sound in all 3 spatial dimensions, as well as being able to move sounds through the space in time - the 4th dimension.
