Music Content Inspector
Music Content Inspector helps you find duplicate MP3 (ogg, aac, mp4, m4a) files in your collection. Unlike other tools that compare file sizes, names and/or tags, Music Content Inspector analyzes the actual content of the file (it `listens` to a portion of the file) and can thereby identify duplicates even if the file names and size are different or the tags are missing. The program also produces a statistical report for the number of files in your collection, their quality, tag integrity and audio formats. Other features include a built-in tag editor and a file manager.
