This page is an overview of the four audio plug-in formats supported by Audacity.
Audacity has built-in support for LADSPA and Nyquist plug-ins, and platform-specific support for VST and Audio Unit plug-ins.

Types of plug-in

Audacity can use four types of plug-in effects:

In Audacity 1.2, you must add the VST Enabler to your computer to use VST plug-ins (the Enabler is essentially a LADSPA interface for VST plug-ins). Audacity Beta has built-in support for VST effects.

How do you add plug-ins to Audacity?

On Windows and Mac, put them in the Audacity Plug-ins folder.

  • On Windows, the Audacity plug-ins folder is usually at C:\Program Files\Audacity\Plug-ins
  • On Mac, the Audacity plug-ins folder is usually at Mac Hard Disk > Applications > Audacity > Plug-ins
For extra paths from which Audacity can load LADSPA, VST or Audio Unit plug-ins, see the respective links in "Types of plug-in" above.
  • On Linux, plug-ins can be added to:
/usr/local/share/audacity/plug-ins or

Free plug-in downloads


  • No real-time effects: Audacity cannot yet preview an effect while changing the parameters of the effect. Audacity cannot yet apply effects to audio while it is playing or recording.
  • VST instrument (VSTi) plug-ins that generate sound are not supported
