SigPath is a native, local-first diagramming app for audio-visual systems. Place devices, patch their ports, and watch cables color by connector while the signal path validates live — then derive pack & patch lists in a click.
A live slice of the real app — drag a device to move it, click a glowing port then a matching one to patch.
Every cable is colored by what it actually carries. The palette is the legend — so a diagram reads the same to you, your crew, and the next engineer.
Devices carry typed ports. Drag port to port and SigPath colors the cable by connector, then validates the mate live — flagging adapters, signal converters, and incompatible runs before they bite you on load-in.
A command palette, a full equipment-database browser, and a guided create-device wizard. Build a gadget once and it lives in your personal library, ready to drop into the next show.
Pack lists and patch lists derive straight from the diagram. Export the canvas to PNG, JPG, or PDF and the lists to CSV — your prep doc and your truck pack from one source of truth.
A real menu bar, multi-window documents, and light/dark themes that follow the system. Local-first and offline — your designs never leave the machine unless you send them.
Pull from the equipment database or roll your own with the create wizard. Each arrives with its real ports.
Drag port to port. The cable colors by connector and the path validates as you wire — green means good.
Derive pack & patch lists, export the diagram and CSVs, and hand off a doc anyone on the crew can read.
No accounts, no telemetry, no subscription. SigPath is a local-first desktop app you own — read the source, file an issue, or build the device library the AV world actually needs.
Free, forever. Download the macOS build today — Windows and Linux are on the way.
