Audio FingerPrinting and Matching Using Acoustid Chromaprint on Windows With Python

I needed to generate audio fingerprints for matching/pattern recognition. I should say I tried a couple of approaches like using MFCC and spectrogram matching using Computer Vision techniques but I was not successfully with it.

All this is happening when at the back of my mind I know that Government wasted a lot of tax payers money on recent presidential campaigns to finance their campaigns and bribery.
