Duplicate cleaner Pro by DigitalVolcano.I have narrowed it down to just seven (7) computer programs (for Windows 7/10/11) that analyze the music for similarity and will find musical duplicates, which in alphabetical order are:
They either rely on naive byte-comparison, or at best use ID3 tags like song title, artist and composer for comparing music files - but these tags are notoriously unreliable for downloaded music.
Most of the aforementioned 102 duplicate cleaners are not "musically savvy".

The bytes may differ, even the waveform itself slightly, but musically-aware software will detect the similarity, almost as a human listener would. Media files need a computer program that can understand the music, not the raw bytes stored in them. What we need therefore is software that can find musical duplicates, allowing for differences in amplitude and recording quality and file formats ( MP3,WMA,AIF,OGG,FLAC,AAC,APE.). It is the same song, but the file size of one is almost double (320kbps bitrate), the duration of one is 4 seconds longer (probably on account of silence at start) and the ID3 tags are all over the place - still they represent the same song!Ġ2-Siva.mp3 6.01MBĚlternativeĐ0:04:25đ90kbps 1991 Take for instance the following 2 music files. Such fingerprints can be used to compare songs, and see through differences in sampling frequencies, loudness and stereo/mono channels, to identify musically identical files - as opposed to binary-identical. Audio fingerprinting algorithms rely on heavy mathematics they "listen" to the music and seek patterns. So a song that you or me would instantly recognize, is hard to tell looking at the raw bytes stored in the file. WAV files are uncompressed, FLAC are compressed but lossless, MP3 files are smallest because they do lossy compression (with a small imperceptible loss of quality). Audio is a wave that can be saved in many different formats, compressions and bitrates. This is fast and safe, but will not work very well for your music file collection. You just examine all the files in your hard disk byte-for-byte, and discover all 100% identical files. The technology behind duplicate file software is quite simple, almost trivial. How do you discover near-duplicate music? We believe that the data are representative, almost scientific :) You are welcome to try your own music library for duplicates - you should find the same results more or less, relatively speaking. The most popular shareware programs that claim to deal with near-duplicate music files are included, and their performance is measured on a fixed set of audio files (music collection library). Clearly the author is biased, but this review is objective.
