I have a folder with thousands of FLAC audio files and i know for sure there are many songs are duplicates. They are mostly re-releases with different names, different ID3 tags, slightly different size and etc.
The problem is that many "audio duplicate finder" software only check that to find duplicates: ID3 tags, file names and size, so they don't work in this case.

I am looking for a software that can ANALYZE audio files (mp3/wav/FLAC,etc) and find duplicates.
Any anon has experience with these kind of software?
