- Worth noticing
- Plugins run in separate processes over shared-memory streams; the page says a basic plugin can be written in ten lines.
Field notes
The described processing path combines tuner input, GPU spectrum work, plugin decoders, and Watch results such as device histories and alerts. The page names Linux mechanisms including memfd rings, futex wake-ups, and io_uring, and says Studio runs pipelines as systemd units. It also describes a radio-sharing bridge for tools including gqrx, rtl_433, and SDR++.
