Is there a way to find / match two same recordings from different sources by analyzing the waveform of selected sounds. I have to find same recordings for reference purposes but nothing is labeled and there are too many files to do it manually in one day (time I have left).

How is your coding? You could put together this functionality using an acoustic fingerprint library such as http://acoustid.org/chromaprint

  • Or use one of the existing services - such as SoundHound - that provides acoustic fingerprint matching. It's only as fast as you can play through the tracks though.

    I assumed you needed to do a lot of files really fast. The method I suggested takes only milliseconds to id a file, even works on audio in video files. I might actually build this tool if there is a need. Commented Jan 30, 2015 at 15:55
  • i think that would be an excellent idea- build away! Commented Jan 30, 2015 at 17:04

If you use or have access to a mac, Similarity should be able to help with this. The free version may be sufficient for your needs.

From the site:

Similarity rapidly scans your music collection and shows all duplicate music files you may have. The comparison powered by "acoustic fingerprint" technology considers the actual contents of files, not just tags or filenames, and thus ensures the extreme accuracy of similarity estimation. Moreover, the comparison isn’t dependent of music file format; the application supports almost every file format in full.
