Similarity 2.3.1 Build 2340 (x86/x64) + Portable Latest– enables you to find & remove music files that have the same or similar sound content an/or music tags (ID3, WMF, Vorbis).
Unlike standard duplicate finders, the program checks the similarity of the actual sound content, not just the music tags or file content as it is done with byte to byte comparison methods. Once the program finished scanning your music folders, it presents you with a list of files along with their similarity analysis. You can then decide to browse, play, delete or create a playlist from the selected files. Similarity supports MP3, WMA, OGG, ASF, WAV, FLAC, APE & WV formats. No expiration. Free to use with basic features.
