4DSOUND enables vivid sonic environments that blur the boundaries between the real and the imagined: the world of sound we know, and a world beyond.

Building on ten years of research, development and experimentation in spatial sound technology, 4DSOUND opens up new possibilities to create, perform and experience sound spatially.




4DSOUND is a fully omnidirectional sound environment where the listener can experience sound in an unlimited spatial continuum. Sound can move infinitely far away or come intimately close: it moves around, as well as above, beneath, in between or right through you. Led by your ears, you’re encouraged to explore the space. You can move between blocks of sound, touch lines of sound and walk through walls of sound. 

4DSOUND was founded in 2007 by composer Paul Oomen and technologists Poul Holleman, Luc van Weelden and Salvador Breed to further the development of new processing software and control interfaces for spatial sound. In the same year, audio engineer Leo de Klerk published his patented application for omnidirectional loudspeakers that enable to produce phantom sound images independent from the place of the listener. Since 2010, Oomen and de Klerk have worked together on the development of the system.


Their approach has led to an innovative system where you do not hear sound coming from speakers: instead, sound appears in the space as a physical entity. The system enables a social listening space in which listeners can move freely to explore a physical environment of sound. 



The 4DSOUND system is a spatial instrument that can be played through integration with a range of interfaces and controllers. Our own software technologies introduce new forms of integrated spatial music performance and sound design, and enable a creative practice of space and movement in music.


4DSOUND also pioneers the integration of other interfaces and control systems to enhance spatial sound composition and interactions, from integrated visual environments and haptic interfaces to touch-, gesture- and bio-feedback systems.

Over the last four years, 4DSOUND has presented showcases of our Artist Residency programme, specially commissioned works and lectures in the context of international festivals such as Berlin Atonal, Amsterdam Dance Event, TodaysArt, IX Symposium Montreal and CTM Festival. 

We develop work with a growing range of composers, musicians and interdisciplinary artists such as Vladislav Delay, Dasha Rush, Pantha du Prince, Murcof, Biosphere, Lisa Park and the experimental Berlin imprint Raster-Noton.

In October 2015, 4DSOUND opened the doors of the Spatial Sound Institute, located at Art Quarter Budapest in Hungary. Consisting of a large-scale spatial sound studio, presentation venue, project space and twenty residencies, the Spatial Sound Institute is dedicated to bring together artists, technologists and researchers from around the world to explore the emerging field of spatial sound.

When 4DSOUND started, it was neither a sound system, nor a technology. Central in the project’s vision was to enable a listening experience that would feel more ‘real’, that would incorporate the physical presence of the listener and the reality of the space sound exists in, and is a part of.

4DSOUND is at the forefront of researching and demonstrating how spatial sound is intertwined with a broader cultural movement that propagates self-awareness, social cohesion and sustainability. Spatial sound is at the heart of a development leading to a new Ecology of Listening - improving the quality of our listening environment to enhance our mental and physical state of being.

Within the enhanced listening environment, both listener and artist can cultivate a reciprocal form of creative listening. This interaction opens up new ways of expression with sound that were not possible before, allowing listeners to develop more subtle, complex and intensive levels of awareness of their environment and their expressions and interactions within it, even leading to examination of the nature of the perception itself.


"The [4DSOUND] system is going to change music as much as the birth of amplification."
"[4DSOUND] allows artists to create a rich, constantly moving and evolving piece that not only sounds amazing, but also comes much closer to what sounds are like in the real world."
