Removing Duplicate music files is nothing new, we have covered two posts before on removing duplicate audio files. Both DoubleKiller and Audio Comparer can find and remove similar audio files. But since no specific tool is 100% accurate in removing duplicate music files, it is always safe to test multiple software.
Similarity is free tool for Windows that uses three different algorithms to find duplicate music files. These algorithms are content based, tags based and experimental respectively. It supports the following file formats, MP3, MP2, OGG, WMA, ASF, FLAC, APE, WF, and WMA, and the following tags ID3v1, ID3v2, ASF, WMA, and Vorbis.
Unlike other tools, this one is quite user-friendly. Just select the folders where you want to compare the music files and it will do the rest. The similarity of Content, Tags, and Experiment is given right in the middle of the screen. It checks bits of content in every music file to find whether they are similar, if it finds the files to be a lot similar you can right-click the file and select Play to check it yourself. It processes the files quite fast and allows you to compare the music files both on your local computer and over a network. It works on Windows 2000/XP/2003/Vista/7. Enjoy!
