Similarity is a program that searches and erases identical or similar music files like MP3, FLA,C WAV and more, along with their sound content and music tags. This application removes duplications making it easier to manage music files.

What makes Similarity stand out from other similar programs is its ability to check the similarity of the sound parts in audio files, rather than just comparing music tags or file content. This means that even if two audio files have different tags or content, but sound the same, Similarity will be able to detect and flag them as duplicates.
In addition to its advanced audio similarity detection capabilities, Similarity also comes with a user-friendly interface, making it easy to navigate and use even if you're not a technical expert. And if you do run into any issues or have questions, the program offers reliable customer support to ensure that you get the most out of your experience.
Overall, if you're looking for a powerful, easy-to-use program to help you clean up your music library and remove duplicate files, Similarity is definitely worth considering.
