Installing Effect, Generator and Analyzer plug-ins on Linux
From Audacity Development Manual
Audacity on GNU/Linux supports a large number of Nyquist, LADSPA, LV2 and VAMP effects. VST effects are now supported in Audacity on Linux and can be installed as described at VST Effects. However native Linux VST effects are quite rare. Consequently, if a specific VST effect is required on Linux, it may be necessary to employ workarounds such as running Audacity for Windows in a virtual machine.
Audacity supports 64-bit effects in VST, LADSPA and VAMP format on 64-bit Linux systems (conversely, 32-bit plug-ins in those formats will not load into Audacity on 64-bit Linux).Contents

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 add a new Nyquist plug-in, put it in the Audacity "Plug-Ins" folder:
- /usr/share/audacity/plug-ins if Audacity was installed from a repository package
- /usr/local/share/audacity/plug-ins if you compiled Audacity from source code.
- Optionally a "plug-ins" folder can be created in the home directory thus: ~/.audacity-files/plug-ins (you can also call the folder "plugins").
These locations are usually set as read-only, so the plug-ins will need to be copied as root (for example, by issuing an appropriate root command in the terminal, or by using the terminal to open a file manager application with root permissions).
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 Linux including "shell" VST's that host multiple VST effects. On Linux, you must add a "plug-ins" folder to /usr/bin/ (if you installed a packaged version of Audacity) or to /usr/local/bin (if you installed a self-compiled version of Audacity). VST effects will also be found if they are added to (or already exist in) various system or user locations.
- All paths listed in the "VST_PATH" environment variable
- If no VST_PATH environment variable is found, the following are searched:
- LIBDIR/vst (where LIBDIR is defined at build time)
- /usr/lib/vst
- /usr/local/lib/vst
- ~/.vst.
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.
If you experience a problem with a specific VST effect plug-in in Audacity, please contact us.
Installing LADSPA plug-ins
LADSPA plug-ins can be installed by putting the plug-ins into the Audacity "Plug-Ins" folder:
- /usr/share/audacity/plug-ins if Audacity was installed from a repository package
- /usr/local/share/audacity/plug-ins if you compiled Audacity from source code.
These locations are usually set as read-only, so the plug-ins will need to be copied as root (for example, by issuing an appropriate root command in the terminal, or by using the terminal to open a file manager application with root permissions).
To load the new effects into Audacity so they are available in the menu, use the Plug-in Manager: Effects, Generators and Analyzers dialog.
- The path specified by the LADSPA_PATH environment variable
- ~/.ladspa
- /usr/local/lib/ladspa
- /usr/lib/ladspa
- $LIBDIR/ladspa
export LADSPA_PATH=$LADSPA_PATH:/home/<user>/.ladspa:/usr/local/lib/ladspa:/usr/lib/ladspa |
If you wish this path to be set each time you boot, the LADSPA_PATH environment variable may be added to ~/.profile or this file may be created if it does not exist. An example of how to add the LADSPA_PATH environment variable:
LADSPA_PATH=$LADSPA_PATH:/home/<user>/.ladspa:/usr/local/lib/ladspa:/usr/lib/ladspa export LADSPA_PATH |
For OpenSuse 64, LADSPA plug-ins may be found in /usr/lib64/ladspa. This path can be set by adding the following line to your /etc/environment file:
LADSPA_PATH=/usr/lib64/ladspa |
LV2 and VAMP plug-ins cannot be placed in the Audacity "Plug-Ins" folder or your .audacity-files folder. LV2 plug-ins should be installed by placing the complete .lv2 folder (not the individual files in that folder) in the root of ~/.lv2, /usr/local/lib/lv2, /usr/local/lib64/lv2, /usr/lib/lv2 or /usr/lib64/lv2. Alternatively the environment variable may be set as in this example:
export LV2_PATH=$HOME/.lv2:/usr/local/lib/lv2:/usr/lib/lv2 |
Installing LV2 plug-ins
LV2 is a more advanced evolution of the LADSPA plug-in architecture which was originally developed on Linux.
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:
- ~/.lv2
- /usr/local/lib/lv2 or /usr/local/lib64/lv2
- /usr/lib/lv2 or /usr/lib64/lv2
- $HOME/.lv2:/usr/local/lib/lv2:/usr/lib/lv2 (assuming $PREFIX is /usr/local as it should be by default)
Then use Plug-in Manager: Effects, Generators and Analyzers.
to enable the LV2 effects and load them into Audacity, For details see
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 GNU/Linux. 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.
VAMP plug-ins may be installed in
- $HOME/vamp
- $HOME/.vamp
- /usr/local/lib/vamp
- /usr/lib/vamp.
Alternatively the VAMP_PATH environment variable may be set to any of those specified VAMP installation directories. VAMP plug-ins will normally be placed in the Analyze Menu of Audacity.
