Getting Dupes Preferences
Get Duplicates at startup
- Immediately initiate getting duplicates at startup using the last-set Playlist Popup and Criteria Matrix settings.
Text comparisons are case sensitive
- Checking this will oblige Dupin to compare text in tags in a case-sensitive manner while Getting Dupes.
Automatically filter when Getting Dupes
- Check this to automatically apply your Filter Controls settings while Getting Dupes. (Note: combining these two tasks is not very speedy.)
Use bit rate rounding to account for ABR encoding
- iTunes 7.5/QuickTime 7.3 introduced ABR (Average Bit Rate) as the default encoding mode for AAC files. This means that files imported or converted as AACs in the same session will have slightly different bit rates which can vary from the selected bit rate by as much as plus-or-minus ten percentalthough not as much as files encoded using VBR (Variable Bit Rate).
When this preference is checked, and "Bit Rate" is selected in the Criteria Matrix settings, Dupin will consider that two or more bit rates are a match if they can round to (ie, are within a minimal range of) the nearest traditional constant bit rate (96, 128, 160, 192, and so on). For example, files encoded at 124 kbps, 126 kbps, and 130 kbps would be considered the same because they are within the range of 128 kbps. If this preference is not checked, two or more files' bit rates must be exactly the same in order to match.
Bear in mind that files encoded at different bit rates will have different sizes, too. Dupin does not perform approximate size matching.
Time Criteria matches +/- seconds
- Used in conjuction with the "Time" Criteria. Check this to enable the horizonal seconds slider and then use the slider to designate a number of seconds between 1 and 10. When "Time" is selected as Criteria, Dupin will consider two or more tracks' times a match if they fall within the number of set secondsplus or minusof the other(s). Thus if the seconds slider was set to 2 or above then 3:04 and 3:06 would be considered a match. (A setting of 4 seconds is probably all that is necessary in most cases.)
When unchecked, two or more tracks' times must be exact to the second to be considered a "Time" Criteria match.
Filter Controls Preferences
Keep Filter Controls window open and on top
- When this is checked the Filter Controls window will remain open and float above all other Dupin windows.
Filter Controls window transparency
- For a less obstructed view of your Dupin windows, you can set the level of transparency of the Filter Controls window.
Designate "Keepers" as: Checked/Unchecked
- Dupin's default behavior is to use a checkmark to designate the Keeper track within a Dupe Group. However, some users prefer the opposite configuration whereby a Keeper is designated by being un-checkmarked. After toggling this setting the new configuration will take effect the next time you start Dupin. In any case, the text color of non-Keepers is always lighter than the text color of the Keepers.
