Editors' Review

It can be a challenge to maintain a pristine music collection once you've migrated to a digital library. With all the moving, copying, downloading, ripping, and transferring files that sometimes goes on, many of us are bound to end up with some duplicate tracks scattered around our hard drives. If you want to get things all nice and tidy again--not to mention clear up some space on your computer--Similarity is here to help. This fairly basic utility scans your system for music files and helps you locate and delete dupes.

Similarity is a quick and light app, with limited options during install. Once you fire it up, you'll be greeted with a minimal interface modeled after Windows Explorer. The left pane lays out an expandable folder list with tick boxes next to each path. Checking off the drives you want to be scanned gets the process started. A simple toolbar lining the top of the window presents the next steps. Clicking the play icon will begin the scan of your music files.

As with most programs that involve a comprehensive scan of media, Similarity requires a fair amount of time during the initial scan. How much all depends on the amount of music you need analyzed. The good news is that the software doesn't task resources too heavily, so you can continue to use your computer during the process.

As for this process, Similarity goes above and beyond simply comparing the track titles and other ID3 tag info for each song. Rather, it actually analyzes files based on various parameters such as bit rate, frequency, amplitude cut value, amplitude average value, and amplitude maximum among others. The program also supports a wide variety of file formats including MP3, AAC, M4A, WMA, OGG, WAV, FLAC, APE, WV, and MPC. In addition to its scan functionality, Similarity offers an integrated tag editor, a spectrum analyzer, and an automatic tag converter.

Once the scan is complete, you'll be able to view some detailed information on all the tracks that have similar selections in your library. The free version of Similarity displays measurements for two factors: the percentage of similar content as gathered from the waveform, and the percentage of ID3 tag similarity. You then have the option of deleting duplicates manually. The premium version, which costs $19.95 for a one-year membership or $34.95 a lifetime license, adds a precision comparison metric as well as the ability to automatically delete or move dupes--a worthy investment if you have a lot of musical clutter.

"Excellent for huge collections (premium is a must then)"

November 19, 2014  |  By GridMike

 |  Version: Similarity 1.8.4

Pros

I had a conglomerate of several mp3 collections, some even double with different versions, totalling in nearly 150'000 mp3s.
It took some days to analyze even on my Xeon workstations with 16 real cores, where similiarity used 100% CPU and went well over 2 GB of RAM, but in the end it really worked out well.
I worked in several passes, always comparing the most complete mp3 collection to one or two of the others and then cleaning up every duplicate in the "lesser" collections. The groups and the automark feature really work well with that.
I could delete more than half of the mp3s with only a few hours of checking, freeing half a TB.

Cons

You definitely need the premium version for that because the precise comparison is the only one that really makes sense. The free version is nice to try out, but not really useful in my opinion. Especially the tag comparison is totally senseless.

Additionally, you need a rather potent PC, at least when you want to takle a larger number of mp3s.

Summary

Only the premium version is useful.

Compared to the time it saved me at sorting out the mp3s, it is worth every penny.

"Says all chamber music sounds the same"

September 16, 2011  |  By rjplummer

 |  Version: Similarity 1.6.2

Pros

Didn't work well enough to find anything positive

Cons

I ran it on my collection and stopped it after it found hundreds of matches for each piece of music.

Summary

It seems like it could tell the difference between chamber music and a full orchestra but that was about it. Also, it seems to think all allegro molto movements are the same piece because they have the same track title.

"Very good at identifying closely-related files."

January 29, 2011  |  By snottgaard

 |  Version: Similarity 1.5.3

Pros

Finds lots of dups.

Cons

Also finds a lot of 'duplicates' in no way related to one another.

Summary

Very good - just be careful what you delete. Maybe the paid version is better at file matching.

"Risky to use."

January 24, 2011  |  By tomthabom24

 |  Version: Similarity 1.5.3

Pros

None I can think of.

Cons

I tried one of these types of programs and ended up with a mess. I would never use one again. It deleted all of my pictures but one all of my videos but one. Alot of duplicate files are there for a reason, I found out later.

Summary

Unless your are really sure you know what to delete, I would stay away from duplicate file cleaners. and never use the auto delete. You can never trust any software to delete automatically for you. Bottom line, stay away from these types of programs.
