"The 4DSOUND system is a spatial instrument that can be played through integration with interfaces and controllers. The concept and technology introduce new forms of musical performance and sound design, and enable a creative practice of space and movement in music."








Built from rough industrial metal, it's comprised of 16 cylinders with the height and girth of young palm trees. These house arrays of speakers, which are nested in three clusters: below waist, at head height and well overhead. The speaker stacks sit in a four-by-four grid on a grated platform that houses low-frequency drivers and generally defines the space. It's about the size of a medium-to-large club dance floor—similar to Berghain, Oomen and I agreed—and I guessed a few hundred people could wind through it without bumping into one another. In its current home, there's also ample space beyond the platform to mill about. Off to the side of the room is a larger workstation, with a souped-up Macintosh and banks of speaker amplifiers. Oomen invited me to start exploring the space while he loaded up some music at the workstation.

In 2006, the Institute of Sonology in The Hague premiered a high-profile, 192-speaker wave field synthesis system at a festival where Oomen was also presenting music. Though he was impressed by the quality of the system, he wanted more. "For me, the idea of experiencing sound in space was very much about not only hearing something that can be around you, but obviously it has to be above you and beneath you. And maybe even more importantly, it has to include the actual space that you are sitting in yourself." The wave field system provided wonderfully detailed surround-sound, but Oomen felt that "the virtual space that I could experience was not going further than the horizontal array surrounding me. I couldn't experience sounds flying through the room or being right there on my lap or inside my head."

"I got very much into his ideas of movement and energy, and I tried to formulate certain rules of movement and energy as I understood them from Tesla's ideas and inventions, and what that would mean if you would start to think about sound and making music. Like, if we start to think about physical movement in space as a parameter in music, what kind of variables do we get?"

The actions of the 4DSOUND system are monitored live in a 3D graphic visualization of the sounds in space.

To provide hands-on control of the system, a 4DSOUND iPad interface has been developed for Lemur. It enables artists to compose and perform their music while being flexible to move through their spatial sound creation.



The iPad interface offers extensive options for immediate performance of the movement, distance, speed, direction and phase of sounds in space.



4DSOUND has a spatial tracking system developed with UWB Sensors that provide real time positional data from persons or objects within the field of the system. The performer can move around the space followed by an aura of sound around their body, or sound can respond to the movement behavior of listeners in the space.


“If creative sound can come from the surrounding world rather than only from a focused, tightly defined source defined by individual authors, then I think our conceptions of art might change in fundamental ways. Instead of assumptions where humans are essentially alone, surrounded by inanimate void, I think the detailed and subtle space created by the 4D system implied a very different picture of the world. Voices and presences can be everywhere. Far from ‘alone’, I found myself inside a renewed kind of present world, surrounded and in a very curious way released and fulfilled.”

“Music has traditionally been about our perception of the frequencies of sound waves. Those frequencies too fast for us to separate are perceived as pitch, yielding melody and harmony, and the slower frequencies of repeating elements yield rhythm. Then there are dynamics, timbre and texture, providing the development and character of a piece of music. The “4D” system literally adds an extra dimension to music categorisation, with the addition of space to this list. How sounds are placed, sized, shaped and moved within the fully 3-dimensional environment of the 4D sound rig has a huge effect on how a piece of music is perceived.”
