this is the old v0.1 of recordara - after "MECHANIZM" & "Calendario" are ready it will be replaced in the master branch
WebSDR Automatic Recorder
main workflow
- load up priyom calendar
- spawn a grabber process per each broadcasast
- grabber flushes out 2 files, one with squelch on
- recordara calculates probable EOF, trims the file, encodes, writes a spectrogram & hands it off to S3
code quality: working PoC
