About
I’m Raoul. I build instruments to look inside sound.
For most of my life I’ve lived between two worlds — audio and image. As a teenager, I was pulled into sound through Einsturzende Neubauten, Kraftwerk, and the raw noise of a Commodore 64. The sound of programs loading from cassette tape. Peek and Poke. Years of sonic experimentation followed — noise, installations, live performance — and eventually Pure Data and Max/MSP became my daily tools.
Professionally, I became a director of photography, specializing in macroscopic imaging, high-speed cinematography, and robotics. I used Max/MSP/Jitter on set to control mechanical effects, lights, and sensors in real time. I spent years looking at things most people never see — the surface tension of a liquid at 10,000 frames per second, the fracture pattern of a material under stress, the way light bends through a lens at macro scale.
At some point, I realized these two worlds — chromatic and spectral in audio, chromatic and spectral in image — share the same material. Convolution, diffraction, morphing, blend, saturation. The same mathematical operations. The difference isn’t the substance. It’s the point of view.
Sound is made of particles and waves at the same time. Change the lens, change the camera, and the image gets clearer. We do this instinctively with our eyes — we isolate parts of a picture, detect motion, perceive depth. Our visual training runs deep. Our auditory training, for most people, doesn’t go as far. But if you can see the sound, the brain starts to hear things it couldn’t before.
That’s what I’m building. Tools that let you change the lens on sound. Look at the same audio from different angles until something you never noticed becomes obvious.
k2k audio
k2k audio is the umbrella for the instruments I build. Right now there are two:
- k2k — a spectral audio explorer and polyrhythmic sequencer. Still in alpha. The main project.
- Modal Compas — a physics-driven generative MIDI plugin inspired by Flamenco rhythmic cycles. Finished and available to Patreon supporters.
Everything is built by one person, with AI coding agents as translators between ideas and C++. This isn’t hidden or apologized for — it’s how a solo artist-developer ships real tools in 2026.
