An audio broadcasting signal disruption sensor and backup program source for providing an alternate audio programming sources in the event of primary- source audio programming failure so as to automatically switch to a backup alternate audio programming source feeding an output audio stream for broadcasting. The system includes monitoring an audio stream from a primary-sources audio programming output, detecting a substantially constant amplitude waveform in the audio stream, determining that tile substantially constant amplitude waveform remains of substantially constant amplitude continuously for a threshold period of time, switching the output audio stream from the primary-source audio programming to the alternate audio programming source upon expiry of the threshold period of time, and providing notice of any main-source audio programming failure to administrative personnel.
