Audio (fingerprinting) duplicate finders - do they really all suck big time? 2017-05-14 14:35:14 I have tried a few free and trialwares. Some of them I need to re-review because I do not remember why I uninstalled each. Currently I have the following five installed. None of them can identify redundant folders/directories, but Duplicate Cleaner promises that the paid version has such a feature.* DupeGuru Music Edition from hardcoded.net:I use this because it quite efficiently scans for audio-only parts, and appears fairly user friendly. It works with my Windows 7, although Windows is not supported anymore - YMMV.This one does not do "fingerprinting", it only has ambition of checking for identical audio. Sucks because:Fails to identify different files with precisely the same audio, because it does not decode. The developer knows e.g. the FLAC format well enough to isolate the audio section from the tags section, but does then evidently just make a hash of the audio part of the file, not the decoded audio. So two FLAC files with different encoding parameters - as well as FLAC and WAV - of the same audio, are not matched.(Since it knows tags, then why not match by MD5 sum? I can use a separate utility to verify that the files are not broken ...)* PerfectTunes from Illustrate (Spoon, the creator of AccurateRip and dBpoweramp, co-developer of fb2k Mobile etc):Does fingerprinting. But: Seems to be no way to score similarity, nor highlight the ones that are bit-identical* Similarity, http://www.similarityapp.com/ Does fingerprinting. Scores in terms of similarity. Has a "quality" meter to help you choose which ones to keep, if you are too lazy for listening; in the least, the "max frequency" figure can help identify upconverted transcodes.Sucks because:Does not distinguish out bit-identical files. Gives a full 100.0 % similarity score even to files which are not identical.Even instrumental vs. vocal versions get nearly full similarity score.Its quality meter has a clipping indicator which is doubtful to say the least. (You just apply gain to the file, and it is instantly fooled.)Does not know WavPack.Does not know ID3v2.4* Mediamonkey with some script for the purpose (where do I find its name?)Only picks a selected portion of the file and makes a hash.* Duplicate Cleaner Free. Too few features in the free version (cannot even identify by audio content), so I can just use Ccleaner instead - but the paid version allegedly scans for duplicate folders and audio content.I guess others have experience to expand the list?
