We were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music.

Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms):

1. Always-on app for listening
2. Compare the audio patterns to a single audio file (assume sound is a simple beep)
3. If beep is detected, send notification to server

With a flow this simple, do you think acoustic fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start?

We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.
