Compare Audio Files to Find Similar or Duplicate MP3

April 1, 2010 | Filed under Audio, Software


Looking for duplicated MP3 or audio on your computer is not going to be the same by using bitrate comparison tool or by checking the MD5 hash because an audio file can be encoded into many types of format. Even MP3 itself can contain a lot of differences such as different BitRate, Channels or Sample Rate which can make the file size different. Even using a different codec to encode an audio into MP3 will result in a different file size for the same song.

Using BitTorrent and Limewire which can download a lot of free music, overtime we will end up with duplicate songs that waste the hard drive space. One easy way to check for similar or duplicated songs on your computer is by comparing the audio files using Audio Comparer.

Audio Comparer can find similar as well as fully identical audio files. The program algorithm works in such a way that different bitrate and compression format do not affect the comparison accuracy. The program can process audio files in various formats. Audio Comparer will find similar files even if one of them has the MP3 format and the second is a WMA format. The supported audio formats are: MP3, MP2, MP1, WMA, OGG, AIF, WAV. Audio Comparer has a unique technology where it listens to your audio files and compares them by their actual audio content, just like your own human ears do.

All you need to do is install the program, add the audio files and Audio Comparer will do the rest. It will display the similarity in percentage which you can listen from the Audio Comparer and decides whether to delete or move it to another location. Audio Comparer is a shareware that cost $34.95 and it allows you to use it free for 30 days.
