I don't know if this is the right place, but I figured the Hoarder Community would have a good idea on software.

I'm looking for an app that will scan an audio library and pick out duplicates. It has to do this by some other means than a mere filename, file size or audio tags. Ideally it would use all of those criteria, and do an audio analysis. I do have all my music sorted, collated, and tagged correctly tho. Opensource would be awesome. Baring that, Free is also acceptable. LOL

If they’re all tagged correctly, then wouldn’t you be able to merely match duplicates based on tags?

https://dupeguru.com/does-dupeguru-support-scanning-music-files/ (dupeGuru is open source) can help with that.

Or filter on open source for the alternatives (such as Czkawka ) to dupeGuru here for alternatives: https://alternativeto.net/software/dupeguru/

Oh, I just found a table of options on https://github.com/qarmin/czkawka with some saying they support audio content matching.

Weird: https://czkawka.com/ has cancer; do not visit it. Seems https://github.com/qarmin/czkawka is the real website.

Ads and “infected” messages all over it. It was first hit on DuckDuckGo. Not sure it was ever legit, or if it was compromised.
