SyncMuse compares two music folders using metadata — not filenames — so it catches duplicates even when the files are named differently. Select a source folder and a target folder, and the app scans both, then labels every track as "New" or "Duplicate." Export all new tracks with one click and they'll be copied into organized, album-named folders ready to add to your library.
SyncMuse compares tracks by title, artist, album, genre, and duration — not by filename. This means it correctly identifies duplicates even when the same song has been saved under different filenames or in different formats. You choose which attributes to match in the settings.
Select a source folder and a target folder and the app immediately starts scanning. It supports MP3, M4A, FLAC, AIFF, WAV, and AAC, and recursively searches all subfolders so no files are missed. Metadata is read via AVFoundation for maximum compatibility.
Once the comparison is done, use the segmented filter to view all tracks, only new ones, or only duplicates. Each row shows the album artwork, title, artist, album, track number, and duration — everything you need to verify the result at a glance.
Hit the Export button, choose a destination, and SyncMuse copies only the new tracks to that folder — automatically organized into subfolders named after each album. A progress bar tracks the copy and you can cancel at any time. Existing files at the destination are never overwritten.
Choose any combination of title, artist, album, genre, and duration as the criteria for a match. A track is considered a duplicate only when every selected attribute matches between the two folders. Your settings are saved automatically and persist across launches.
SyncMuse reads metadata using AVFoundation, giving it broad compatibility with all major audio formats. It extracts title, artist, album, genre, artwork, track number, and duration from each file. Subfolders are scanned recursively, so deeply nested libraries are fully covered.
The comparison results are displayed as a rich list showing album artwork, title, artist, album, track number, and duration for every file. New tracks get a green "New" badge; duplicates get a red "Duplicate" badge. Use the filter control to focus on exactly what you need.
Select a destination folder and SyncMuse copies every new track there, placing each file inside a subfolder named after its album. If a file with the same name already exists at the destination it is skipped automatically. The originals are never moved or deleted.
Choose a source folder (your existing library) and a target folder (the new collection you want to check). SyncMuse scans both and reads the metadata from every supported audio file it finds.
Every track in the target folder is labeled "New" or "Duplicate." Use the filter to view only new tracks or only duplicates, and browse the artwork-rich list to verify the results before exporting.
Click Export, pick a destination folder, and SyncMuse copies all new tracks there — sorted into album-named subfolders automatically. A progress bar shows how the copy is going, and you can cancel at any time.
"I had music scattered across three hard drives and had no idea what was duplicated where. SyncMuse sorted it all out in minutes. The metadata matching is the key — it caught duplicates that had completely different filenames, which no other tool I tried could do."
"I use this every time I buy new albums online to check whether I already have any of the tracks before adding them to my library. The album-folder export means everything lands in the right place automatically. Huge time saver."
"I manage a mixed FLAC and MP3 collection and this app handles both perfectly. Adding duration to the match criteria lets me distinguish remastered versions from originals, which is exactly what I needed. Fast, clean, and simple."
