Functionality for validating if an specific audio is playing on the device

There are several audio fingerprinting systems available, however most of their libraries are not updated recently and many of them expect a remote comparison service available with a collection of already fingerprinted music files, which might not be suitable in our case. There is one library that keeps a local database - musicuri, but the code might need to be refactored to make it Android compatible and get rid of the console output.

A real issue might be the inability to capture the currently playing audio in order to compare it with the fingerprinted music files in the db. There are some posts that suggest this is possible with the Visualizer API, but the audio is very low quality. More info here.
