NBFM recorder

For what it’s worth, this is a simple project I wrote that reads N
channels from a file and streams the narrow band FM audio to audio sink
and wav file (removing the dead space). I use it for monitoring 2 meter
repeaters and simplex channels. I’m able to monitor 27 channels across
the entire 2m band with a USRP N210 and VOLK enabled (that makes a
bigdifference) on a 3 GHz I7. That of course goes down as the RF
bandwidth is increased, but it will do 8channelsacross a 25 MHz
bandwidth.
