Hi there, you also need to download the file chromaprint-fpcalc-1.5.1-windows-x86_64.zip (1.5 MB) from https://acoustid.org/chromaprint

Then please unzip the binary file (.exe) into the same folder with the compare.py.

After that, you should see the fpcalc.exe is in the same place with compare.py and correlation.py. Hence in line 30 in correlation.py, the subprocess can be able to call the fpcalc for your audio file

And if you found the same error as me while comparing audio files like:

    ...
  File "H:\audio-compare\correlation.py", line 37, in calculate_fingerprints
    fingerprints = list(map(int, fpcalc_out[fingerprint_index:].split(',')))

ValueError: invalid literal for int() with base 10: '3497912292\\r'

You can add the .replace("\\r", "") to line 30 in correlation.py. Your line 30 should end up like this: fpcalc_out = str(subprocess.check_output(['fpcalc', '-raw', '-length', str(sample_time), filename])).strip().replace('\\n', '').replace("'", "").replace("\\r", "")
