Field notes
The page presents a browser app and a command-line script for removing aircraft and vehicle tones and mains hum from recordings. Its example follows a turboprop blade tone from 128 Hz on approach to 80 Hz after passage, then explains how paired observations can be matched against public ADS-B tracks. The site says the browser runs the same roughly 550-line Python file through Pyodide, with video handled by Mediabunny and browser codecs; it says clips remain on-device.
