Duplicate MP3 Finder

Duplicate MP3 Finder box shot

Audio Comparer is a tool that can help you find and remove duplicate songs. It can scan your collection and identify duplicate songs based on their audio content. This means that even if two songs have different file names or are in different formats, Audio Comparer can still identify them as duplicates.

Once Audio Comparer has found the duplicate songs in your collection, you can then choose to delete them or move them to a different location. This can help you declutter your music collection and free up space on your hard drive.

The Audio Comparer Lets You:

  • Find and remove duplicate MP3 files automatically
  • Identify duplicate music regardless of the format or missing tags
  • Root out files that have been misnamed
  • Organize files into trees based on audio similarity level
  • Create audio groups for refined analysis

There are a few ways that you can find duplicate songs on your computer. You can search for duplicate songs manually. This can be done by opening up your music folder and looking for files that have the same name or are the same size. Alternatively, Audio Comparer can listen to all your music in less than a second per song, remember their actual sound, and locate duplicates and similar songs in a few more seconds.

Audio Comparer features unique duplicate recognition technology

Able to work with MP3, MP2, MP1, WMA, AIF, WAV, WavPack, FLAC, APE, AAC, and OGG audio files, the Audio Comparer offers unprecedented file comparison abilities. Unlike the other duplicate MP3 finders that are designed to scan for tags or file size, the Audio Comparer actually "listens" to the songs themselves, analyzing and recognizing them based on their sounds just like the human ear. No matter what codec or bitrate your files are saved as, the AC can identify the duplicates.

How does it work?

Audio Comparer begins by listening to your entire music collection in every format and remembering it all. You can choose to have AC view your files as one big audio collection, or you can divide your music content into smaller audio groups. In fact, it takes only a second or two to "listen" to an entire MP3 file! Equally quick is the audio comparison process; you'll begin to see results within seconds. The results will be displayed in a tree layout, with branches connecting files based on the degree of similarity within each parent branch.

Practical applications for the Audio Comparer:

  • Have duplicates in your iTunes library? Audio Comparer can find and remove them automatically.
  • Does your collection include plenty of different audio formats, codecs, and bitrates? The Audio Comparer can sort it all out.
  • Do you have audio files with missing tags? Audio Comparer is the only tool capable of identifying and removing tag-less duplicate audio files.
  • Operate a broadcasting station? Produce a podcast? Avoid accidentally playing misnamed audio files at inappropriate times.
  • Feeling like your collection takes up too much space on your hard drive? The Audio Comparer will help you get things under control in no time at all.
