The Python program which pulls this off is given below, comparing files in a directory with Monday's content to files in another directory with Saturday's content. The audio fingerprinting is done using fpcalc in Chromaprint (http://acoustid.org/chromaprint); fpcalc should be placed in the same directory as the Python script. Chromaprint samples the audio content at 11025 Hz with …
