Founded in 2026, Arcsin Engineering was built by a team of engineers dedicated to building products for anything you can imagine. We stand at the intersection of design and engineering without compromise.
Arcsin Engineering makes mobile signal processing tools for musicians who perform live. Our hardware is compact. Our software is fast. Everything we build is designed to work under pressure — bad lighting, loud monitors, no time to debug.
Our first product, the LIMIT-1, is a mobile hardware multieffects unit with an iOS companion app. It combines JUCE-powered C++ audio processing with a SwiftUI interface, keeping latency below 10ms while giving performers full control from physical knobs and a touch screen.
We believe the best gear gets out of your way. No menus, no modes — just the sound you need when you need it.
Each layer speaks its native language. Swift owns the UI. C++ owns the DSP. Objective-C++ translates between them — no compromises in either direction.
