Audio Dedupe is not an ordinary duplicate mp3 finder. As it performs a true audio analysis it can find duplicate mp3 files even if they are not marked with ID3 tags. This is also the reason why the tool can compare MP3, MP2, MP1, MPA, WAV, OGG, AIFF, AAC, MP4, FLAC, AC3, WavPack (WV), Musepack (MPC) and Windows Media Audio (WMA) file formats. Most of the duplicate finder applications on the market claim to find duplicate mp3 files while actually they only compare the file size or content. In best case most of the tools just look at the ID3 tags and compare titles which provides very poor results. Audio Dedupe performing a true audio scan can find even remix of the same song. You can easily control the similarity level in order to find exact duplicates or include variations of a song.
The duplicate MP3 finder tool is provided in three variations - Standard, Professional (Pro) and Corporate. The table below lists the differences in functionality between these three variations of the tool.
|Can find similar audio files|

|Find similar and duplicate ID3 Album|
|Can use embedded player|
|Can use auto-check|
|Can locate files in Windows Explorer|
|Can move/delete duplicate files|
|Can open files with their associated program|
|Can use Quick Check/Uncheck|
|Can save/load projects|
|Can use filter|
|Can automatically delete empty folders|
|Can export results to CSV or XML|
|Can disable folder for self-scan (exclude folder)|
|Can compare folders|
|Can use command-line features|
Command-Line Parameters Usage: (Available only in Corporate Version)
AudioDedupe.exe -src_list <srclistfilename> -target_list <targetfilename> -log <logfilename> -s <similarity> -db <dbfilename> [-cachenames]
-src_list <srclistfilename> - specifies a plain text file which contains file names that you want to compare against <targetfilename> files
-target_list <targetfilename> - specifies a plain text file which contains file names that you want to compare against <srclistfilename> files
Note: If you omit -target_list parameter only -src_list files will be scanned
-log <logfilename> - specifies full path file name where the log from the comparison will be saved, e.g. c:\log.txt
-s <similarity> - specifies a similarity in percents. Example: -s 70
-db <dbfilename> - specifies the cache file name to be used or created.
-cachenames - if this option is specified, the program will store file names in cache instead of files checksum
Note: Cache files store audio files information gathered during the preprocessing pass (1st pass) of the scanning process. So if you often scan the same files, using cache file speeds up considerably the preprocessing pass.
You don't need to create the cache file. Just specify it as a parameter and the program will create it. Or if the cache file from previous scan exists the program will use it. The cache files extension is ADCF (Audio Dedupe Cache File).
Example: AudioDedupe.exe -src_list "c:\src.txt" -target_list "c:\target.txt" -log "c:\log.txt" -s 70 -db "c:\db.adcf"
This will find all audio files with similarity >= 70% and save their file names and similarity in c:\log.txt file
Note: If some of the parameters contain spaces, you must enclose them in double quotes. Example: -src_list "c:\program files\files.txt"
Sample src.txt and target.txt file contents:
|C:\My Documents\MP3\Track (3).mp3

C:\My Documents\MP3\Track (4).ogg
C:\My Documents\MP3\Track (5).mp3
C:\My Documents\MP3\Track (6).mp3
C:\My Documents\MP3\Track (7).mp3
Sample log.txt file contents:
