recordara

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

1. load up priyom calendar
2. spawn a grabber process per each broadcasast
3. grabber flushes out 2 files, one with squelch on
4. recordara calculates probable EOF, trims the file, encodes, writes a spectrogram & hands it off to S3

code quality: working PoC

grab.js standalone
