Intergalactic Sound and
System Engineering

Audio DSP and engineering, phase-coherent across parsecs.

A DSP house with an unreasonably wide listening field.

IGSSE Oy is a limited liability company specialising in audio digital signal processing, embedded audio software, and system engineering. We build the kind of code that turns silicon into sound — and occasionally the other way around. Our impulse responses may be local, but our ambitions have a much wider sample window.

From bit to orbit.

Three core practices, infinite combinations. Every project starts with a careful read of the signal — and ends somewhere it didn't expect to be.

DSP Software Development

Real-time audio algorithms, filters, convolution engines, and embedded firmware. C, C++, Rust, and whatever else the deadline orbits closest to.

// where the only aliasing is intentional

Audio Engineering

Measurement, tuning, room correction, and the dark arts of getting things to sound the way they were always supposed to. Calibrated ears, calibrated tools.

// signal-to-noise ratios astronomers would envy

R&D & Consulting

Prototyping new audio products, technical due diligence, and quietly fixing whatever it was the last engineer left in the codebase. We bring receipts and impulse responses.

// group delay measured in light-years (we're still early)

Project enquiries, collaborations, or general transmissions — we typically respond within one Earth-rotation.
