This app supports 12 audio formats like MP3, WMA, OGG, WAV and FLAC. Using the “acoustic fingerprint” technology, it can compare the actual content of music files and detect the similarity.

This duplicate files finder does a very good job of finding duplicate songs. It will look for duplicates and display them in the Audio Results window. However, it’s not that user-friendly. The interface isn’t intuitive or straightforward enough. And some options can be confusing to users, especially beginners. The Automark files option is of limited use. In our test, it didn’t mark all the complete duplicates.

Note: By default, the app will find both duplicate and similar music files in the folder of your choice. To set it to only look for duplicates, go to Preferences > General > Audio comparison methods and set the Content similarity level to 100%.
