GNU Radio Compiled to WebAssembly Runs Live SDR Flowgraphs in the Browser With WebUSB Hardware Support
gnuradioworld.com / Hacker News (207pts)·low signal
GNU Radio World compiles the GNU Radio DSP stack and Qt GUI sinks to WebAssembly so a flowgraph runs with live spectrum, waterfall and constellation plots without Python, an install or a server. It reads and writes native .grc files, ships example flowgraphs and IQ recordings, and reaches RTL-SDR, PlutoSDR and HackRF hardware through WebUSB. Attribution points to GitHub user 777arc.
