Audacity Plugins
This site features download links to various plugins for Audacity, which can be used to extend Audacity's functionality to better match your workflow.
On this site you can find download links for equalizer plugins, filter plugins, delay and reverb plugins, and more. If you'd like to download many plugins at once, you also can try entire plugin suites.
All plugins in the realtime effects section can be used instantly and non-destructively from the effects panel in Audacity.
This means that you can change the effect settings while playing, and come back to your settings after doing many other things - without the need to undo anything, or to wait for the effect to be applied to the track.
Further information about using realtime effects can be found here:
Installing plugins
When you install plugins, they're automatically enabled the next time you restart Audacity. Alternatively, you can also locate and enable them via Effect -> Plugin Manager -> Rescan Plugins. Further instructions can be found here:

On Mac OS X only, you can add Audio Unit plugins to the system plugin directories.
