Similarity is a clever freeware program that locates identical music files on your computer so you can delete the extras and just have one version. What’s v. cool is the fact that the software ‘listens’ to the sound content, rather than just relying on filename, size etc.
You can adjust the sensitivity as you need, and it copes with just about all music files from MP3, OGG, WMA and beyond. If you’re like me, and have music (and photos for that matter) scattered about on multiple disks like confetti, then this will definitely be a keeper.
Similarity is a useful program that helps you to find and remove similar, duplicate musical files (MP3, WMA, OGG, ASF, WAV, FLAC, APE, WV) with the same or similar sound content, music tags (ID3,WMF,Vorbis). This is the best program where similarity of a sound part is checked, not just music tags or file content (byte to byte comparision). In addition the program analyzes the artist, title, album information from the music tags contained in the audio files and compare these with the appropriate entries in other files.
