COMMANDS

Getting data from the monitor db
================================

* select data from intercepts where freq=95955000 order by date, time into outfile "dbout" fields escaped by '';
 (*** This results in messed up output if there's more than one row comprising the audio; don't use it)

* You can do this: mysql --binary-mode -e "select group_concat(data separator '') from intercepts order by date, time;" -A -B -r -L -N freqwatch -u freqwatch -p > output

* Or better yet, use intercept.py

Some things to do on the command line
=====================================
* cat file | play -t raw -r 32k -e signed-integer -b 16 -c 1 -V1 -

* # Decode FM broadcast stations
  rtl_fm -f 95.7e6 -s 170k -A fast -r 32k -l 0 | play -r 32k -t raw -e s -b 16 -c 1 -V1 -
    (they suggest using -E deemp, but that doesn't work for me)
