Identify Duplicate Files by Sound
Music Duplicate Remover will find duplicates of audio files on your computer. There are two different ways of doing that:
- locate duplicate files by their ID3 tags and parameters;
- identify duplicates by "listening to" audio, that is by comparing the sound.
Both things can be done manually, and that's how some people still manage their music collections. However, looking for duplicate files by browsing folders takes pretty much time and effort.
Music Duplicate Remover was created to make the process of finding duplicate files much easier, faster and more precise. In just a second it scans a bunch of music files and compares their ID3 tags and parameters to locate duplicates, the speed impossible for a human user. But listening to music files is pretty different, can we rely on a program there?
Let's try. Start the program. On the left, all folders available on your computer are shown. Check boxes near folders that you want to scan for duplicate files:
If you see no folder structure area on the left, make sure that the "Folders" button is depressed on the toolbar.
Now move a bit to the right and select "By sound" from the "Compare" dropdown list. The "Compare" list offers three preinstalled duplicate detection schemes.
If you'd like to adjust settings, click the "Show settings" link on the left. This will expand the area, and additional settings will be shown.
For duplicate search by sound we can adjust threshold and maximum difference values. The lower is the threshold value, the more files will be found as duplicates. However, if the value is to low, there is a chance that different files will be detected as duplicates. If you are not sure about these settings, you can simply skip the step.
Finally, click the "Find duplicates" button on the toolbar to start looking for duplicate files in the selected folders.
The program will show a progress window:
Click the "Background" button to minimize the program and allow it finding duplicate files in the background.
When the scan is finished, a message containing statistics will be shown.
Close it to browse the found duplicates.
On the screenshot above, we can see that the program has found duplicate files. Some of them don't have any ID3 tag information at all, so they cannot be found by ID3 tags.
Now we can delete duplicates by clicking the "Remove duplicates" button on the toolbar.
But we may want to reverse the list (keep the files with ID3 tags and remove files with empty tags instead). This can be done quite easily, see how to sort duplicates.
To make sure that files are really duplicates, you can preview them in the built-in or in an external player. If you'd like to make the list of duplicates more readable, please feel free to adjust fonts and colors.
If you are not sure about deleting duplicate files right now, the program allows to move them into a folder of your choice. See if your collection is good without them.
