Where are Preferences stored?
Audacity Preferences are stored in a configuration file called audacity.cfg. It is a text file saved on each clean exit of Audacity and can be edited with any text editor. The file is stored inside Audacity's folder for application data:
- Windows 2000/XP: Documents and Settings\<user name>\Application Data\Audacity
- Windows Vista/Windows 7/Windows 8: Users\<user name>\AppData\Roaming\Audacity\
- OS X: ~/Library/Application Support/audacity/
- Linux: ~/.audacity-data/
However if you create a folder called "Portable Settings" in the same directory as the Audacity executable, "audacity.cfg" will be stored there instead. If you copy this "Portable Settings" folder to a USB stick or CD this lets you take your current Audacity settings with you if you use Audacity on another computer.
Resetting preferences to factory defaults by initializing the audacity.cfg settings file to its original contents can sometimes fix freezes, crashes or unexplained behavior.
- Exit Audacity.
- Open audacity.cfg in a text editor such as Notepad and remove all the content except the line NewPrefsInitialized=1 (you can find this at or near the top of the file when you open it).
- Save the changes to audacity.cfg and restart Audacity.
- In order to see audacity.cfg on Windows, Linux and OS X 10.7 or later, you need to show hidden files and folders. See instructions for all versions of Windows and OS X 10.7.
- If you have never previously run a 1.2 version of Audacity on your computer, you can reset preferences more easily by deleting audacity.cfg while Audacity is closed. See below if you have previously run Audacity 1.2.
Windows users may alternatively run the .exe installer from http://audacity.sourceforge.net/download/windows which has an option to reset preferences.
- To reset preferences, navigate to the "Select Additional Tasks" screen then put a check mark in the "Reset Preferences" box. After completing installation, launching Audacity will display a dialog where you can confirm if you want to reset preferences this once, or not.
- If you run the installer but do not choose "Reset Preferences", the installation files will be replaced with correct copies just as when choosing to reset preferences, but the Audacity settings will remain as before. This is unlikely to correct most Audacity problems.
