The Mono Hawk — a precise chromatic tuner for guitar and bass on Linux (LV2). Sub-cent detection — resolves to about a tenth of a cent on a steady signal — down to a 5/6-string bass low B (~31 Hz). Hardware-style X11 + Cairo interface, 50 tunings, a reference-tone generator, and silent-tuning mute.
Drop-in LV2 bundle — no build step.
Install:
mkdir -p ~/.lv2 && tar -xzf themonohawk.lv2-0.1-linux-x86_64.tar.gz -C ~/.lv2/
Then rescan plugins in your host; it appears as "The Mono Hawk Tuner". Insert it on a mono track.
Requirements: Linux x86_64 with an LV2 host, plus the Cairo and Xlib runtime libraries.
Built mainly with Claude Code. GPL-3.0-or-later, no warranty — see the README. A polyphonic detector was prototyped but isn't shipped (patent-encumbered); the method is written up in POLYPHONIC-METHOD.md.
