I just installed audacity and tried to correct a sample music recording. The Repair Effect is not listed on the Effect menu and the Click Removal doesn’t seem to work?
Get the latest Audacity 2.0.5 from http://audacityteam.org/download/windows .
Effect > Click Removal is not the only way to remove clicks. You can get help with Click Removal and Repair by reading these links:
