Send Audio Event Based Email

Using Arduino Project Guidance
1

I'm the operations manager at a small market radio station, with a bit of a problem.

Our automation system freezes approximately once a week, and when it does, then there's nothing on the air (a big no-no).

If I'm not the first one to hear it, then I get a phone call from my boss and his boss wondering why I haven't done something about the dead air yet.

In order to make it where I do not have to listen to the radio 24/7 (as much as I live and breathe radio, a brother needs to have a life as well!), I need to build a device I can input audio into, it reads the audio, and if at any point there is an interruption in the audio, it will automatically send an email to myself so I can fix it.

I know I will need an audio shield and an ethernet shield, and I've seen code for both connecting to the internet and event based emails, my primary questions regard to what board I should get to make sure I have the processing power to complete these tasks, and also how to make the event audio based.

Any ideas? This little project would benefit my career exponentially.

Any assistance would be PHENOMENAL. Thanks!

Your project sounds totally possible with an Arduino UNO plus an Ethernet shield, plus some simple components to connect the audio from your radio feed into an analogue input on the Arduino

There are plenty of examples of using the Arduino as an audio spectrum analyser, so I suspect that using that library would be a good starting point for determining whether there is signal or not.

However you'd need to do some additional coding to check whether any breaks in the audio are a natural pause or a real breakdown, e.g silence for 5 secs could be the trigger.
