To install new LADSPA or Nyquist plug-ins, place them in the Plug-Ins folder inside the Audacity installation folder. On Windows computers, this is usually under "Program Files". On Mac OS X, it is usually under "Applications". On Linux, you can use various plug-in locations. Restart Audacity, then the addded plug-ins will appear underneath the divider in the "Effect", "Generate" or "Analyze" menus.
Audacity has built-in support for LADSPA plug-ins. These plug-ins are mostly built for Linux, but some are available for other operating systems too. Audacity includes some sample LADSPA effects. Windows users can install an additional set of over 90 LADSPA plug-ins. There is a similar set of LADSPA plug-ins for Mac. More information and many LADSPA plug-ins for Linux can be found on the LADSPA web site.
Audacity has built-in support for LV2 plug-ins, which are an extensible successor of LADSPA effects. LV2 plug-ins are mostly built for Linux, but Audacity supports LV2 on all operating systems. To install LV2 plug-ins, place them in the system LV2 location then restart Audacity.
Audacity has built-in support for Nyquist effects on all operating systems. You can download additional Nyquist plug-ins, or create your own using the Nyquist programming language. Nyquist code can be tested using "Nyquist Prompt" under the Effect menu, or code for Nyquist plug-ins that generate audio can be quickly tested with Nyquist Generate Prompt.
On Windows and Mac, Audacity can load VST effects (but not VST instruments). The VST Enabler is no longer required. Enable "Rescan VST effects" in the Effects Preferences and restart Audacity when you want to add new effects. See "How do I install VST plug-ins?" for more information.
VST effects can be found on many plug-in sites such as:
Audio Unit Plug-Ins
On Mac OS X only, Audacity loads Audio Unit plug-ins automatically from system plug-in directories. Audacity will not recognize any Audio Units in its own "plug-ins" folder.
The FFmpeg import/export library allows Audacity to import and export many additional audio formats such as AC3, AMR(NB), M4A and WMA, and to import audio from video files. Audacity 2.0.6 and later requires FFmpeg 1.2 or later (or libav 0.8 or later). To install FFmpeg, please read our FFmpeg FAQ.
