Similarity is an extremely useful program that helps you to reorganize your music collection and bring some order to it. It contains a tag editor, a tag converter, a powerful mechanism of searching duplicates (based both on the simple tag comparison and on complex algorithms of “acoustic fingerprint”), a musical collection quality analysis system and an experimental function of tag auto-filling.
Similarity uses several comparison methods: by audio-file tags and also methods, based on the “acoustic fingerprint” technology. The “acoustic fingerprint” technology strongly differs from usual binary comparison or comparison of file hashes. Audio-files cannot be compared byte by byte, as most of them aren’t 100% byte copy of each other. They usually have different file size, different bit-rate and even different codec. That is why Similarity sticks to “acoustic fingerprint” technology. This method based on the strong math shows perfect results.
