I have a massive music library (all mp3), but I some of the music is almost the same but:Maybe one or two second longerAbout 97% the same as another songOr another bitrate.Is there a way to find these duplicates? As mentioned they don't have the same size, name, or SHA1-hash.
Remove duplicate mp3 with different name, size, and hash
mp3;music;duplicate
There's an open source acoustic fingerprinting system called Echoprint, you might want to check I want to deduplicate a big collection. I haven't used it before (just stumbled across it), but it sounds awesome to be able to do this locally.
