Do you mean the LADSPA “Hard Limiter” plug-in?
Which version of Audacity are you using? (look in “Help > About Audacity”)
Which version of Windows?
If you are using a recent version of Audacity, there is a new Limiter effect included that generally gives better results than the old LADSPA effect: http://manual.audacityteam.org/man/limiter.html
