File Menu

The File menu has the following items:

Clear Database iGain caches the analysis data for each track in an internal database. The Clear Database menu clears this internal database. Use this command if audio files are modified outside of iGain, for example by running MP3Gain or AACGain directly from the command line.
Sync with iTunes When iGain is started for the first time, it will automatically read all tracks and playlists from iTunes. From then on, this command must be used whenever new tracks are added to iTunes, in order make them visible to iGain.
Cancel This command is used to abort processing of other commands.
Exit This command terminates iGain.
