We believe the future of sound is spatial.
That’s why we envision, design, and build spatial sound instruments, systems, and installations — empowering artists, researchers, and institutions with access to technology and expertise for immersive sonic experiences. Welcome to Slovox, the R&D Lab for spatial sound.
Slovox for practitioners
Making a living in sound and music is tough — unless you’re ready to go beyond the traditional. Spatial sound is still wide open for those willing to experiment.
Spatial sound used to be expensive and inaccessible. It's time to change that. Slovox exists to empower sound artists with know-how and technology to explore immersive sound formats, and build fulfilling, sustainable careers.
The possibilities are limitless • live performance • electronic music • electroacoustic composition • art installations • theatre • choreography and dance • living architecture • history & heritage presevation • mindfulness, meditation & well being • sonic therapy • psychoacoustic research
Slovox for institutions
Convincing immersive sound doesn’t just come from an impressive spend. We know that wonderful things happen when artistic intent meets a willingness to experiment and rethink what’s possible, all while staying resourceful.
Slovox combines the artistic know-how with technology for art spaces, museums, academic programs, and research labs to advance spatial audio and invite new ways of listening.
We build our own products and welcome collaborations, to enable dialogue and participation. We believe technology should bring people together and foster social listening, never isolate or overwhelm.
We design tools for listening
We build objects and systems that invite curiosity, dialogue, and new ways of experiencing sound together. Each project is a step towards making spatial audio more accessible, adaptable, and socially engaging.
Singing Watermelons
Our flagship development, a family of parametrically-designed spherical loudspeakers — omnidirectional, multichannel, ambisonic, or beamforming.
Think the lighthouse of sound
These instruments project precisely directed beams that sweep through space, shaping sonic phenomena that move and transform within a room — making spatial sound feel alive and tangible.
With architecture, not against it
Unlike conventional systems, you don’t hear the speaker — you hear sound interacting with architecture, creating evolving sonic sculptures.
And unlike ambisonic domes or surround systems, the experience is not limited to a narrow sweet spot, inviting artists and audiences to explore entire sound field, with the environment being a co-creator, not the obstacle.
Standing on the shoulders of giants
Built on years of pioneering research at IEM Graz, this project wouldn't be possible without the work of Franz Zotter, Stefan Riedel, Matthias Frank, Gerriet Krishna Sharma, and others.
Not only their work realized the long-held dream of reproducing the spatial character of real instruments, once envisioned at IRCAM, but opened avenues for orchestrating space and beamforming with the IKO, and several DIY offshoots. For us, it's inspiration, invaluable foundation and… the beginning.
Our approach
We prioritize adaptability and affordability, enabling more practitioners to engage with spatial sound. Using modular, parametric design, we’ve created not a single, but a family of instruments for diverse creative scenarios.
If IEM’s IKO is a double bass and the 393 a violin, we’re building the violas and cellos — compact, versatile, and opening a wide space for sonic experimentation.
Modular Ambisonic System
A spin-off of Singing Watermelons re-applies the same design principles, this time to a conventional outside-in sound system, bringing spatial audio to a wider range of spaces and scenarios.
Modular Control & Amp Racks
Our compact, portable multi-channel DA conversion and amp units power both systems using off-the-shelf components, delivering robust performance and exceptional value.
Part of The Last Ear
Slovox is the R&D lab of The Last Ear, a platform dedicated to restoring the art of listening in an age of engineered distraction.
Our work is grounded in attentive sovereignty, creative collaboration, and the belief that listening is a radical, essential act for the future. Every project is an invitation to advance the art and science of listening, dissolving boundaries between artist, audience, and environment.
