Where are Preferences stored?

Audacity Preferences are stored in a configuration file called audacity.cfg. It is a text file and can be edited with any text editor. The file is stored at:

• Windows: Documents and Settings\<user name>\Application Data\Audacity\audacity.cfg
• OS X: ~/Library/Application Support/audacity/audacity.cfg
• Linux: ~/.audacity-data/audacity.cfg

However if you a create a directory called "Portable Settings" in the same directory as the Audacity executable, "audacity.cfg" will be stored there instead. This facilitates transfer of the user's customized settings (for example, via a USB stick) if Audacity is used on another computer. Note: a workround is needed where audacity.cfg is on a computer running OS X.

Resetting Preferences

Resetting preferences to factory defaults can sometimes fix freezes, crashes or unexplained behavior. To reset Preferences if you have never used a previous Audacity 1.2.x version:

1. Exit Audacity
2. Delete audacity.cfg
3. Restart Audacity

If you have previously used Audacity 1.2.x, deleting audacity.cfg will roll back those preferences common to 1.2 and 2.0 to their current 1.2 settings (even if you have since uninstalled 1.2.x). To reset 2.0 preferences to factory settings where you have previously used 1.2:

1. Exit Audacity
2. Open audacity.cfg in a text editor and remove all the content except the line "NewPrefsInitialized=1"
3. Restart Audacity

Another way to completely reset 2.0 preferences on a machine which has previously run 1.2 is to delete the old 1.2 settings file as well as audacity.cfg. The 1.2 settings are stored in the "audacity" file in your Library (OS X), the file ~/.audacity (Linux) or the Windows registry key HKEY_CURRENT_USER\Software\Audacity\. Note: Modifying the Windows registry is dangerous - always back it up before modifying it.
