Audio Dedupe by MindGems Inc. is a tool that is very handy in such situations. Unlike the standard duplicate file finders on the market, the tool is aimed exactly towards finding duplicate audio files. What is even more interesting is that it does not need audio tags like ID3 in order to accomplish that. Audio Dedupe performs a real audio scan using complex algorithms in order to find audio files that sound alike. Due to that fact Audio Dedup can recognize a song even if it is stored in several different file formats - MP3, MP2, MP1, MPA, WAV, OGG and AIFF.
Once the scan process is complete Audio Dedupe will list all the duplicate audio files sorted by groups of two or more files. It provides a handy auto-mark feature that can mark files choosing files with lower quality, older date or smaller size for deletion. You can also listen to the files using the internal audio player and compare them. The embedded audio player has a continuous playback feature that lets you switch between the duplicates while they are playing. Once you are done with the review of the results you can choose weather to move the files to a certain folder (backup), delete them to the recycle bin or completely remove them from your hard drive. If your files are organized in folder Audio Dedupe will also maintain the folder structure of the moved files in the target location.
It is easy to keep your audio collection clean as Audio Dedupe will also remember the already scanned songs and every consequential scan will be even faster. Cleaning up duplicate audio files can save you gigabytes of valuable disk space and using a similar tool is a must.
