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.
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.
Further information about using realtime effects can be found here:
When you install plugins, they're automatically enabled the next time you restart Audacity 3.2. Further instructions can be found here:
Note: Audacity 3.1.3 does not yet support VST3 plugins.
This site is still in development.
If you want to add your own plugin, or one that you found on the web, read the contributing instructions.
Audacity has built-in support for Nyquist effects on all operating systems. You can download additional Nyquist plugins, or create your own using the Nyquist programming language. Nyquist code can be conveniently tested using "Nyquist Prompt" under the Effect menu.
Audacity has built-in support for LV2 plugins, which are an extensible successor of LADSPA effects. LV2 plugins are mostly built for Linux, but Audacity supports LV2 on all operating systems. To install LV2 plugins, place them in the system LV2 location then use the Plugin Manager to enable the new plugins as in the plugin installation instructions.
Audacity can load VST effects (but not VST instruments) on all operating systems.
Starting with Audacity 3.2, VST3 effects are also supported on all operating systems.
LADSPA is superseded by LV2. These plugins are mostly built for Linux, but some old LADSPA plugins are available via the Legacy Windows and Legacy Mac sections.
This site is only meant as a starting point for effects. There are many more plugins, particularly VST3 ones, available on various vendor sites, directories and online stores. Some of them are listed below:
