Audio detecting email notifier.
Schematic for Raspberry Pi in links.
Detection of unbalanced line level audio (a.k.a. headphone jack output at loud volume) which will send a single email when audio is dead and a single email when its active.
Uses: DEAD AIR monitor for a radio station.
See: http://github.com/ClockLoop/NodeRedDeadAir for schematic.
