About Us

Welcome to Guitar Tuner Online, built by Signal Void Industries. Our mission is to democratize high-end audio tooling by providing professional-grade software directly in your web browser.

Our Technology

We leverage the latest advancements in the Web Audio API and cutting-edge YIN pitch detection algorithms to deliver clinical accuracy (±0.01 cents) with virtually zero latency. This means you get the responsiveness of an expensive hardware pedal directly on your phone or laptop.

Why We Built This

As musicians ourselves, we grew tired of ad-ridden apps, paywalled features, and clunky interfaces. We set out to build a clean, beautiful, neo-brutalist tuner that just works. Whether you're in standard tuning, dropping to C for metal, or calibrating your bass, we have you covered.

Free Forever

We believe essential tools for musicians should be universally accessible. Guitar Tuner Online is and always will be 100% free.
