Options menu


The Options menu has the following items:
Always on Top If this option is checked, the MP3Gain window will always stay on top of other windows.
Work on Selected files only If this option is checked, then only those files that are currently selected will be operated on if you do an Analysis or Gain.
Add Subfolders If checked, then when you Add a Folder, all of the mp3s in all of the folders inside the selected folder will be added to the list.
Preserve file date/time If checked, changed files will keep their original timestamp. If unchecked, file timestamps will change when Gain changes are applied.
No check for Layer I or II MP3Gain will only work on mp3 files. On rare occasions, MP3Gain will mis-identify an mp3 file as an mp2 or mp1 file and refuse to do analysis or gain changes on the file.
Enabling this option forces mp3Gain to skip the safety check, allowing you to change the gain on these mis-identified files.

Be careful, though; if you have any mp2 or mp1 files that are accidentally mis-named as mp3 files, then when you use MP3Gain to make gain chages on those files, the program will just corrupt the data in those files.

Don't clip when doing Track Gain If this is checked, then when you do "Track Gain", if the suggested Track gain will cause clipping then MP3Gain will apply the maximum non-clipping gain instead
Tags See the Tags help page
Logs... You can have MP3Gain record its operations to various logfiles. Selecting this item will launch the Logs window:

You can specify the directory and filename for log files that will collect all errors, analysis results and changes made.

Toolbar You can modify the look of the toolbar with this item. Available options for the toolbar are:

Big Buttons
Small Buttons
Text Buttons
No Buttons

Filename Display You can select how files are displayed in the File List. By default, files are shown with their full path and filename. Available options for the filename display are:

Show Path/File
Show File only
Show Path & File (as separate columns)

Minimize to Tray If this option is checked, then when you minimize the MP3Gain window it will appear as an icon in the system tray notification area (the little rectangle in the bottom right corner of your screen) instead of appearing on your taskbar.
Useful for keeping your taskbar clean while MP3Gain is working in the background.
Beep when finished If checked, then MP3Gain will make a default beep sound when it finishes a task.
Reset Default Column Widths This option will reset the column positions & sizes to their default settings. Use this if you accidentally hide a column under another, or off the screen.
Reset "Warning" messages The first time you perform some actions in MP3Gain (Clear Analysis, for example), the program pops up a dialog box with a warning message. On this dialog box, there's a check box that says Don't ask me again. If you check that box, the program stops showing that particular warning message.

Clicking Reset "Warning" Messages makes those warning messages start popping up again.

Advanced... Advanced options allows you to modify Thread Priority and Performance variables, and allows you to turn on "maximizing" features.

Thread Priority This adjusts what priority the program has in using your computer's resources. If you know what this means, feel free to play with this setting. If you don't know what this means, just leave it alone :)
Performance Checking these boxes might make MP3Gain run slightly faster on your machine. Unfortunately, it also might make your computer freeze up when you apply Gain changes. If that happens, just reboot, start MP3Gain again, and un-check the box you checked.
Enable "Maximizing" features "Maximizing" is the word I use to describe what most audio programs call "normalizing": finding the maximum amplitude of sound files and setting them to a specified level.
This is not a good way to make audio files sound like they're the same volume. It was my experience with a "normalizing" program that made me write MP3Gain.
When you check this box, a message pops up with a link to some files that demonstrate the volume differences that can remain between songs when you maximize the amplitudes of audio files instead of volume normalizing.
