A free, local-first, native macOS app for designing AV signal-flow diagrams.
SigPath is an engineering-grade diagramming tool for audio-visual systems — place devices, wire their ports, and the app colors cables by connector type, validates the signal path live, and derives pack lists and patch lists. Built to be fast, offline, and instrument-like for broadcast and AV engineers.
- Connector-aware canvas — devices with typed ports; cables colored by connector, with live signal validation (adapter / converter / incompatible).
- Add-device flow — a ⌘K command palette, a full equipment-database browser, and a guided create wizard saving to your personal library.
- Reports — auto pack lists and patch lists; export the diagram to PNG/JPG/PDF and the lists to CSV.
- Native macOS shell — menu bar, multi-window documents, light/dark themes that follow the system.

Logo and icon assets live in design/logo/ (SVG sources, app
icon, and the dots mark). The six dots are the signal kinds — video, audio, A/V,
network, control, power.
