Holosonic Beamforming
Compact spherical arrays
Our technology is built around compact spherical beamforming arrays — holosonic projectors that emit precisely directed beams of sound and let space do the rest. Instead of building a perfect, dead room, we use reflections and architecture as active parts of the instrument, creating explorable 3D sound sculptures in real‑world spaces.
Space as Medium
With architecture, not against it
Conventional systems try to make space disappear: dead rooms, heavy treatment, and surround arrays that only work from a single sweet spot.
Our instruments project into the room and let sound interact with surfaces and volumes, so you hear sound shaping the space — and the space shaping the sound — wherever you move.
One Platform Versatile use
Our instruments work in several spatial modes, so you can choose the workflow that matches your practice and tools, from simple setups to advanced research environments.
Beamforming
Higher‑order ambisonic streams decoded to highly directional beams that can be steered and shaped for ultimate spatial resolution.
Ambisonic
Higher‑order ambisonic decoding to the array for 3D soundfields with spectrally limited directivity.
Multi-channel
Per‑driver discrete channel routing for intuitive DAW workflow, experimental composition or live patching.
Volumetric
Multiple instruments distributed in space for holophonic soundfields, for example using 4DSound's engine, Logelloop's Acousmonium or IRCAM's SPAT.
Design Principles
Parametric, portable, precise
All Slovox arrays share one parametric design and matched electronics. That means consistent acoustic behaviour, predictable performance, and configurations that scale with your space and practice — from compact units that fit in cases to larger projectors that can carry a room.
- Parametric family of layouts and sizes
- Built to order, with room for customization where it matters.
- Tuned and measured individually, with dedicated filters.
- Matched amplification and control in portable racks.
On the shoulders of giants
IEM Graz
This platform stands on pioneering research at IEM Graz by Franz Zotter, Matthias Frank, Stefan Riedel, Gerriet Sharma, and others — whose dedication work made it possible to orchestrate space with compact arrays, building on IRCAM’s original vision. We’re building from that foundation to make it practical, accessible and advance the field further.
Integration
Work with your tools
Our platform is designed to slot into existing spatial sound ecosystems rather than lock you into a proprietary stack. You can work with familiar hosts and plugin suites, as long as they provide sufficient multichannel capabilities. We can help you choose the right combination for your use case.
- DAWs and live environments (Reaper, Max MSP).
- Spatial plugin suites and engines — HOA/ambisonic toolchains, research platforms.
- External diffusion and holophony engines where needed.
From Lab to Practice
Built in use, not on paper
Our technology has been developed inside our own artistic and research practice before being offered to others. We continue to evolve it with early adopters, labs, festivals, and venues — treating each deployment as a feedback loop that refines the platform for real‑world conditions, not just idealized test rooms.
Next Steps
Choosing the right setup
Selecting a configuration is less about “bigger is better” and more about how you want to work with space. We prefer to start with your workflow, intended spaces and audiences, then propose an instrument that fits — and grows with you.
