|This page describes support for VST (Virtual Studio Technology) effect plug-ins in Audacity; VST instrument plug-ins that generate audio are not supported. A list of VST effects known to process correctly in Audacity on Windows is given here.
VST support in Audacity
VST effects are displayed with full GUI interface (where provided by the plug-in), and without need of the VST Enabler. This has been made possible by use of an open source VST header.
When Audacity is first launched, a Register Effects dialog will appear which lists VST plug-ins detected in the Plug-Ins folder inside the Audacity installation folder and in other system locations. Press OK to load the chosen plug-ins. Your VST effects will appear in the Effect menu, underneath the divider.
When you restart Audacity again it will reload the plug-ins it detected last session, as stored in the pluginregistry.cfg file stored in the Audacity folder for application data. This avoids slowing down each Audacity launch by scanning for new plug-ins.
To add a new VST effect most easily, put its DLL (Windows), VST (Mac) or SO (Linux) file plus any configuration files or folders it requires in the Audacity "Plug-ins" or "plug-ins" folder inside the directory where Audacity resides.
- Go to the Effects Preferences
- Under "Plugin Options", ensure that the checkbox "Check for updated plug-ins when Audacity starts" has a checkmark, then click OK (this checkbox should be enabled by default, so this step is usually not required)
- Restart Audacity then in the Register Effects dialog, verify your newly added VST plug-ins have a checkmark and click OK.
Where Audacity looks for VST plug-ins
The complete list of locations can be found in the Manual at http://manual.audacityteam.org/o/man/effect_menu.html#syslocs. The specified directories are searched recursively, which means that plug-ins that are inside their own folder in that directory should still be found by Audacity.
List of functional Plug-ins
|Instructions for adding plug-ins to the list:
- The majority of plug-ins will be for Windows only unless OS 9 or OS X is stated.
- Classic Mac OS plug-ins will only work under OS 9 and previous. Mac OS X plug-ins with a .component file marked as "PowerPC" will only work on PPC Macs (they might work on Intel Macs with slow performance under Rosetta but Rosetta cannot be used on OS X 10.7 or later).

List of Plug-ins with known problems
|Instructions for adding VST effect plug-ins to the list:|
|Auto-Tune||Windows||Dec.2012||Audacity 2.0.1||Tuning by MIDI input is not supported.|
|BlueCat||OS X||Sep.2014||Audacity 2.0.5, 2.0.6||In 2.0.5, the plug-in interface does not work, so you can only use default settings. The interface works in 2.0.6, but in both versions, saving a preset will lock out the main Audacity window, requiring to close Audacity from the Dock.|
|CM Vocoder||Windows/OS X||Sep.08||Audacity 1.3.8+||Does not appear|
|Effect Chainer DX and VST wrapper||Windows||Jan.08||All||can't host any plug-ins|
|FFX-4 DX and VST Wrapper||Windows||Jan.08||All||can't host any plug-ins|
|Freeverb2||Windows 7||Oct.11||Audacity 1.3.13||Only tabular interface, no preset support|
|GRM Tools||OS X||May 2014||Audacity 2.0.6-alpha||Interface cannot be used (so the effects can only be used at default settings) or interface disappears completely when loading preset. The interface is likely to be available in 2.0.6 release, but attempting to save a preset in any Audacity version could lock out the main Audacity window.|
|GRM Tools||Windows||Sep.08||Audacity 1.3.8+||unspecified|
|GSnap||Windows||Jan.2014||Audacity 2.0.6||Tuning by MIDI input is not supported.|
|keFIR||Windows||Apr.08||VST-Bridge 1.1||has no effect on audio|
|kn0ck0ut||Windows||Sep.2014||Audacity 2.0.6-alpha||Despite Audacity 2.0.6 or later supporting buffer delay compensation, the start of the processed audio has silence inserted and a corresponding length is removed from the end of the processed audio. This also occurs in Goldwave and Wavosaur so is probably a bug in Kn0ck0ut, but the VST version is no longer being developed, only an LV2 version.|
|Sonic Maximizer||Windows||Sep.2007||VST-Bridge 1.1||not in Effect menu|
|SoundSoap2 (discontinued) (see also SoundSoap3)||Windows, OS X||2007 (various)||All||Audacity won't launch|

|VisualVOX VST||Windows||Jan.2008||VST-Bridge 1.1||No interface, just silences audio|
|T RackS 3||OS X||Dec.2009||All||Audacity won't launch|
|Waves V5||Windows||Dec.2012||Audacity 2.0.2||Hangs Audacity on launch|
