Audio Comparer enables you to find similar or duplicate MP3, WMA and OGG audio files on your computer even if the file names are different and tags are missing. Unlike standard duplicate finders that only compare files by size or hash value, Audio Comparer compares the files by actually listening (internally) to a portion of the sound content and then presents you with a list of likely duplicates. You can then choose to move, copy or delete selected duplicate files and clean up your collection. Your comparison results can be saved for later processing and also compared with other file groups.

Audio Comparer is a must-have tool for every music lover. Even if your music collection is not large there are surely several duplicates in there. If you have a phenomenal audio memory you may try to find duplicates yourself, though that would be very hard work. Audio Comparer tool will do it for you. No matter what audio format your songs have, no matter they are perhaps without tags. Audio Comparer doesnt need tags or pay attention to the format. It just listens to your audio files like a human ear and remembers your entire collection. Then the tool can quickly locate similar and duplicate audio files.
