Duplicate Finder 2009

<< < (3/8) > >>

sajman99:
Curt, I finally looked at this program to see what is so "advanced" about it. Leaving aside Ashisoft's business practices which I know nothing about, the program is a decent software with aesthetic appeal. It has a logical layout, skinnable interface, and accurately detects Byte by Byte or CRC32 duplicates. But I have several freeware tools that do just as well finding duplicates, though they may not be packaged as nicely. If Duplicate Finder 2009 would incorporate visual similarity analysis (like Dup Detector, VisiPics, etc), then I would be more impressed. Binary duplicate detection in a commercial product doesn't inspire me (and other freeware junkies) to run for the credit card.

However, as you suggested Curt, the Music Duplicates (MP3/WMA) analysis is a whole different ball game. It is much more "advanced", or at least new territory. These music duplicate analysis tools seem to be gaining popularity, as they are emerging in both the commercial and freeware landscape. I just recently noticed that two commercial sites which have done well with image duplicate/similarity software now have music duplicate/similarity software for offer:  
Audio Dedupe at http://www.mindgems.com/products/Duplicate-MP3-Finder/Audio-Dedupe-About.htm, from the developers of Visual Similarity Duplicate Image Finder &
Audio Comparer at http://audiocomparer.com from the developers of Image Comparer http://www.bolidesoft.com.

Likewise, new freeware offerings include Similarity 0.9 at http://www.music-similarity.com and Music Content Inspector 1.0 beta at http://www.sloud.com/technology/music_content_inspector. These tools are rather raw and undeveloped at this early stage, yet they typically cover more file types than Duplicate Finder 2009 which only appears to cover MP3 and WMA.
EDIT: DF2009's documentation indicates it supports .ogg files. I ran several tests on my .ogg files, and the program didn't find files that the freeware Similarity did find. But if DF2009 supports .ogg, then I stand corrected on this issue.

Curt, your urging to test a program before drawing conclusions turns out to be solid advice. When I saw this thread months ago, I thought "another binary duplicate detector, who cares?" Well, turns out I do because of the music content analysis feature. I won't be purchasing this particular software, but your posting opened up a new avenue of software exploration. All of which is to say- thanks for posting. :Thmbsup:

The beginning of your post surprised me because I never would have thought about using DP2009 for image comparisons. I know that the author/company are trying to give the impression that it is for all kinds of comparisons, but it is targeted, as you then go on, for audio files. At least, that is the only thing I ever have tried to use it for. And because I only have MP3 and WMA in my music collection I didn't know about the limitation in supported extensions.

DP2009 and Audio Comparer are more or less equally good, but Audio Comparer suits me best. However, to me it is not always about using the best program, only, but also about taking part in developing/maturing - which is why I use more than one program for the job.

Thanks for telling about http://www.mindgems.com/products/Duplicate-MP3-Finder/Audio-Dedupe-About.htm - I have been searching for that one but had forgotten the name!  :up:
Edited: Do (any of) you know what will happen if I let Audio-Dedupe run (for a week) to compare 40.000 files? Can it handle such a job? Vista, 32-bits, 4 GB.

Curt:
Now I remember why I didn't purchase the Mind Gems program(s) the first time I tried it/them. I strongly prefer share*it (Digital River) over RegSoft (also Digital River!!). And it is possible for me to use share*it if I want to buy a copy of the image-dupe finder, but not possible if I want to also have the audio-dupe finder at the same time! Then I will have to use RegSoft only!

Innuendo:
sajman99, you seem to be up on this type of software. Hopefully, you'll let us know which program(s) you think are the best at detecting dupes (and why). I could really use a good dupe-finding program, but would really appreciate an opinion from someone who has tried them all.

sajman99:
After exploring these music analysis tools a bit further, I can now declare my preference for Mindgems' Audio Dedupe. Its results were spot-on accurate, illuminating multiple duplicate songs I didn't know existed in my collection of approximately 10,000 songs. For example, it seems Sheryl Crow and Kid Rock had the same song entitled "Picture" on each of their respective albums. Who knew? Apparently not me because I have two copies of the same song, albeit at different bitrates.

In accordance with MindGems' policy at http://www.mindgems.com/products/Duplicate-MP3-Finder/Audio-Dedupe-About.htm :
The Demo version of Audio Dedupe is not trial, but with the following limitations:
You cannot delete or move the selected duplicate files using Move or Delete Selected buttons.
You cannot use Open with Associated Program and Locate in Explorer popup menu items.
You cannot Save/Load projects.

I also tried the two freeware tools noted above, and I can only give my opinion: they're still too beta-ish to be useful. Since Similarity is updated fairly regularly and really looks promising, I intend to watch its development carefully.  

@Curt: 40,000 songs? Wow, that's a substantial music collection. Audio Dedupe analyzed 10,000 songs in roughly 45 minutes on XP, 32-bits, 4 GB, E6850. Unless Audio Dedupe unpredictably grinds to a halt, I would expect it to easily complete 40,000 files over the course of one day/night, certainly not an entire week. ;D

Also, the freeware Duplicate Cleaner at http://www.digitalvolcano.co.uk/content/duplicate-cleaner cites the ability to "Deep scan music formats - mp3, wma, flac, ogg, ape, etc", but all it does for me is crash when I attempt to scan music files on an external HD. >:(  Without actually testing the program, I cannot say what "deep scanning" really means (ie. how advanced is this software?). In any event, others may have better luck with Duplicate Cleaner so I'll pass along the info FWIW.
