Installing Audio Unit plug-ins
- Audio Unit effects support real-time preview.
To add a new Audio Unit effect, place it in either of the following system plug-in directories:
- ~/Library/Audio/Plug-Ins/Components (user plug-ins)
- /Library/Audio/Plug-Ins/Components (system-wide plug-ins)
Then use Manage Effects.to enable the Audio Unit effects and load them into Audacity, For details see
Installing Nyquist plug-ins
Nyquist plug-ins provide most of the optional effects underneath the divider in the Effect menu. They are also used to provide some of Audacity's built-in audio generators and analysis tools. A wide range of additional Nyquist effect, generation and analysis plug-ins can be obtained from Download Nyquist Plug-ins on our Wiki.
To install new Nyquist plug-ins, place them in Audacity's "Plug-Ins" folder at ~/Library/Application Support/audacity/Plug-Ins.
To load the new effects into Audacity so they are available in the menu, use the Plug-in Manager: Effects, Generators and Analyzers dialog.
Installing VST plug-ins
Audacity supports almost all VST effect plug-ins on Mac including "shell" VST's that host multiple VST effects.
To install new VST plug-ins, place them in Audacity's "Plug-Ins" folder at ~/Library/Application Support/audacity/Plug-Ins.
- All paths specified by the "VST_PATH" environment variable.
You can install new VST effects into Audacity by using the Plug-in Manager: Effects, Generators and Analyzers dialog where you can select and enable the new effects then click to load them. Next time you launch Audacity the enabled effect(s) will be cached and you will not need to re-enable them.menu item. This opens the
Why do some VST plug-ins not work or display incorrectly?
Audacity will by default display VST effect plug-ins with a full graphical interface where the plug-in supplies this.
VST instruments (VSTi) (such as synths) and real-time VST effects (that change the audio data while it's being written) are not yet supported. These will not load even if you enable or re-enable them in the Plug-in Manager: Effects, Generators and Analyzers dialog. VST 3 plug-ins are not supported.
If any plug-in displays incorrectly, you can use the Manage button in the effect's dialog then choose Options... to open the VST Effect Options for that effect. Then remove the checkmark from the "Enable graphical interface" checkbox and click . When you reopen the effect it will display a simpler tabular interface.
|On Mac, Audacity is a 32-bit application so will not see 64-bit versions of VST plug-ins, even on 64-bit operating systems.|

Installing LADSPA plug-ins
The LADSPA plug-in architecture was originally developed on Linux. Audacity supports LADSPA effects on Mac as well as GNU/Linux. You can download and install a set of over 90 LADSPA plug-ins. You can then choose which LADSPA plug-ins to enable in the Plug-in Manager: Effects, Generators and Analyzers dialog.
To install new LADSPA plug-ins, place them in Audacity's "Plug-Ins" folder at ~/Library/Application Support/audacity/Plug-Ins.
- The path specified by the LADSPA_PATH environment variable
Installing LV2 plug-ins
LV2 is a more advanced evolution of the LADSPA plug-in architecture which was originally developed on Linux. Audacity supports both LV2 effects on Mac as well as GNU/Linux. There are not yet many pre-compiled LV2 plug-ins for Mac, though it may be possible to compile some Linux LV2 plug-ins for other operating systems.
To add a new LV2 effect, place its complete ".lv2" folder (not the files alone) at the top level of any of the following searched for locations:
Installing VAMP plug-ins
VAMP plug-ins are usually for analyzing audio so will appear under Audacity's Analyze Menu. You can do interesting things like attempt to track beats, note pitches, chords or frequencies. Any VAMP plug-ins whose output is suitable for a label track should work in Audacity on Mac. To add a new VAMP analysis tool, add the plug-in's DLL, DYLIB or SO file and any supplied category or RDF files to any of the VAMP search locations then enable the tool in the Plug-in Manager: Effects, Generators and Analyzers dialog.
Plug-ins can be removed usingand then removing the file from the relevant file location, so that they do not appear again in Plug-in Manager.
Plug-ins shipped with Audacity can be found inside Audacity.app (in the Applications folder, or wherever you have installed Audacity). The path to the plug-ins is for example /Applications/Audacity.app/Contents/plug-ins. You can reach the Contents directory by right-clicking or CTRL-clicking over Audacity.app and selecting Show Package Contents.
