Noise Gate problem

My name is Patrick Michaud, and I do not have Noise Gate as one of my options under the “Effects” drop down menu. Do I need to download it? Or should it already be there? Either way - how do I get it onto my “Effects” menu so I can edit out breath noises in between talking?

Thanks,

Patrick

There is a Noise Gate effect available here: http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Noise_Gate
