Duplicate Audio Finder

Find and remove duplicate audio files on your computer using Duplicate Audio Finder.

Duplicate Audio Finder detects similar audio files by using audio fingerprinting. It listens to your audio files to determine similarities and does not rely just on file size, format, or audio metadata.

Thanks to audio fingerprinting, Duplicate Audio Finder can identify the same audio in different audio file formats. It supports most file formats, including wav, wma, mp2, mp3, mp4, aac, flac, ogg, m4a, ac3, webm, ape, flv, avi, f4v, mac, mov, and tta.

The audio matching method used by Duplicate Audio Finder can detect similar audio files regardless of file size, bit rate, sampling frequency, or audio quality. Duplicate Audio Finder will detect two audio files that sound similar to you.

Duplicate Audio Finder can also detect similar audio files of different durations. If one audio file is slightly shorter or longer than another audio file, Duplicate Audio Finder can still identify them as duplicates.

Duplicate Audio Finder can detect duplicate audio files that have different recorded volumes. The matching algorithm is also immune to noise and audio filtering. You can also change the similarity setting to find only exact matches or more matches.

You can also easily delete, move, or copy duplicate audio files with Duplicate Audio Finder. Duplicates can be deleted/moved/copied without having to manually navigate to file system directories.

Duplicate Audio Finder accelerates the detection process by using multiple CPU cores. You can also adjust the multi-core speed-up level using the settings.

Thanks to the built-in audio player, you can easily listen to the detected duplicate audio files and confirm their similarity.
