The options available to change the criteria when searching for duplicates are given in the "Duplicate Search Criteria" box on the left hand side of the Tune Sweeper window.
Checking any of the boxes in this window will change the way Tune Sweeper determines if a track is a duplicate of another in iTunes.
Tune Sweeper always compares the Name of the tracks when considering if the tracks are duplicates.
For example, if only the Artist box is checked - two tracks are seen to be duplicates only if the Artist and Name of the tracks are the same.
In the example shown here, two tracks are determined to be duplicates if the Name and Artist of the track are the same and if the tracks lengths are no more than 3 seconds different.
Using these settings gives you a very powerful set of tools when analysing your iTunes library for duplicate tracks.
Click the 'Search' button to re scan your iTunes library for duplicates based on the modifications you have made in the 'Duplicate Search Criteria' box.
What do the preferences do?
Here's a run-down of the function of each preference option:
Artist - Two tracks must contain the same Artist to be considered the same.
Album - Two tracks must contain the same Album name to be considered the same.
Track# - Two tracks must contain the same track number to be considered the same.
Track Count - Two tracks must contain the same album track count to be considered the same.
Time - The duration of two tracks must be within the given number of seconds of each other to be considered the same. Change the time limit using the slider. For example, with this setting set to 3 seconds a track of duration 4:25 and 4:22 would be considered the same (provided their Names match also).
Podcasts - If the Podcast box is checked - all Podcasts are excluded from the duplicate search.
iTunesU - If the iTunesU box is checked - all iTunesU tracks are excluded from the duplicate search.
TV Shows - If the TV Shows box is checked - all TV Shows are excluded from the duplicate search.
Searching Duplicate Groups
You can search duplicate groups using the search field located to the top right of where the groups are listed. Simply type the name of the Artist, Album or Track Name which you would like to search for and Tune Sweeper will automatically run the search.
In the example above we have decided to search for "Cheryl". Only groups with fields containing "Cheryl" will now appear in the groups section.
You can now choose which groups/songs to ignore during the remove process. Once you are finished with these searched groups you can press 'Clear' next to the search field. This will re-display the full list of duplicates. Any modifications you have made to the duplicate groups are kept when they are re-listed in the full list of duplicates.
