Try running your library through Fakin The Funk. Source: over 1 year ago

Spek and Fakin' the Funk are two tools that will tell you what you've truly got; Audacity will also do it if you ask it for a frequency analysis. If your mp3 has a hard shelf at 16kHz, it's a 128, no matter what the file says it is. Source: over 1 year ago

I've used Czkawka (https://github.com/qarmin/czkawka) because it does Lanczos-based image duplicate detection, which makes it more practical for me. - Source: Hacker News / 8 months ago

Maybe it's a setting you made or the files, not sure. You can try another software czkawka to see if you get better results with it. Source: 9 months ago

For static images I used https://github.com/qarmin/czkawka and it works well enough. I think. But when I used it on a folder with gifs and their jxl conversions, it shows nothing. SURELY this could not be user error, rrrright? Source: 10 months ago

I used to use DupeGuru which has some photo-specific dupe detection where you can fuzzy match image dupes based on content: https://dupeguru.voltaicideas.net/ But I switched over to czkawka, which has a better interface for comparing files, and seems to be a bit faster: https://github.com/qarmin/czkawka. - Source: Hacker News / 12 months ago
