Scroll down to the seventh post in that thread to get the latest version. Once you’ve downloaded it, put it in the plug-ins folder inside the Audacity folder (or wherever you have installed Audacity) and restart Audacity. Read the thread for instructions on using it. You might be able to get that 4.1 dB back.
