LADSPA Plug-ins

LADSPA (Linux Audio Developers Simple Plug-in API) is an audio plug-in standard originally developed on Linux, but which can be ported to Windows and Mac too. Audacity has built-in support for LADSPA plug-ins.

Writing LADPSA plug-ins

Audacity behaves as an excellent LADSPA host. Just read up about LADSPA, and make your plug-ins correctly. As a starting point, look at some LADSPA Plugin Developers’ Documentation and some example plug-ins. Keep in mind that Audacity «runs» the plug-in multiple times with some specific number of samples. So, don’t assume that your plug-in will get the entire selection the first time.

Obtaining LADSPA plug-ins

• Windows and Mac: Any LADSPA plug-in compiled as a Windows .dll or Mac .dylib shared library will work on these platforms. An extensive set of «swh» plug-ins by Steve Harris is available for Windows and Mac.
• GNU/Linux: The easiest and recommended method of obtaining pre-compiled LADSPA plug-ins is to install them using the download repository or package manager for your distribution of Linux. Other LADSPA plug-ins can be found online such as at http://linux-sound.org/ladspa.html. However in some cases downloading plug-ins from external sites will require you to compile the plug-ins yourself, or at least manually install them yourself.

Using LADSPA plug-ins

For instructions on how to load new LADSPA effects into Audacity please see this page in the Audacity Manual.

On GNU/Linux, if you have the ladspa-sdk installed, you can run listplug-ins from a terminal to list all plug-ins in your LADSPA_PATH .

Plug-Ins

You can download and install plug-ins or libraries to add extra functionality to Audacity. Plug-ins can give you extra effects, or more audio generation and analysis capability. Adding libraries can allow you to import or export additional audio formats.

Plug-in Installation

Installation instructions for plug-ins are provided in the Audacity manual. Note that the instructions vary according to platform (Windows / Mac / Linux) and the type of plug-in.

Nyquist Plug-ins

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 conveniently tested using “Nyquist Prompt” under the Effect menu.

LV2 Plug-ins

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 use the Plug-ins Manager to enable the new plug-ins as in the plug-in installation instructions.

VST Plug-ins

Audacity can load VST effects (but not VST instruments) on all operating systems. The VST Enabler is no longer required. Install the VST effects to the Audacity Plug-Ins folder on Windows, to

/Library/Application Support/audacity/Plug-Ins on OS X/macOS or to system locations. Then use the Plug-ins Manager to enable the new plug-ins as in the plug-in installation instructions above.

VST effects can be found on many plug-in sites such as:

The VST Plug-ins page on the Audacity Wiki contains further help for VST plug-ins, and lists a large number of VST plug-ins that have been reported to work well in Audacity.

Audio Unit Plug-ins

On Mac OS X only, you can add Audio Unit plug-ins to the system plug-in directories (Audacity will not recognize any Audio Units in its own “plug-ins” folder). Then use the Plug-ins Manager to enable the new plug-ins and any required Apple Audio Units as in the plug-in installation instructions above.

Module Plug-ins

Experimental modules offer a further way to extend Audacity with new features.

LADSPA Plug-ins

LADSPA is superseded by LV2. These plug-ins are mostly built for Linux, but some old LADSPA plug-ins are available via the Legacy Windows and Legacy Mac sections.

Libraries

The LAME MP3 encoding library allows Audacity to export audio in the popular MP3 format. LAME is now bundled in with the latest Audacity version.

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 to 2.3.x (or libav 0.8 to 0.10.x). To install FFmpeg, please read our FFmpeg FAQ.

How to contribute?

Installing Effect, Generator and Analyzer plug-ins on Windows

It is strongly recommended, when installing third-party plug-ins, that you thoroughly test the plug-in on non-critical project data before using it in production use on a live project.

Many such plug-ins are known to fail or crash Audacity, see this Wiki page.

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.

The easiest way to install a new Nyquist plug-in is to use the Tool Nyquist Plug-in Installer which is itself a Nyquist plug-in that simplifies the installation of other Nyquist plug-ins.

All Nyquist plug-ins are plain text files that have the filename extension ‘.NY’. This plug-in installer provides a file browser for selecting the plug-in ‘.NY’ file, and then copies the file to the correct location. Once the plug-in has been installed, it may be enabled in the Plug-in Manager.

Accessed by: Tools > Nyquist Plug-in Installer.

Installing a Nyquist plug-in manually

It is also possible to add a new Nyquist plug-in manually by adding it to the correct location that Audacity expects.

Place it in the Audacity «Plug-Ins» folder: Users\\ \\AppData\\Roaming\\audacity\\Plug-Ins

If you are a privileged user and you need to install a plug-in for use by multiple user accounts on the same PC you may also install Nyquist plug-ins to the Plug-Ins folder in the directory where Audacity is installed.

This is usually: C:\\Program Files\\Audacity or, C:\\Program Files (x86)\\Audacity on 64-bit machines.

To enable the new effects into Audacity so they are available in the menu, use the Plug-in Manager: Effects, Generators and Analyzers dialog.

Some Nyquist plug-ins could crash while processing very long audio selections (typically an hour or more). This is due to the plug-in using a large amount of memory and is a known issue in Audacity’s current Nyquist implementation. Try using the plug-in on shorter selections instead.

Installing VST plug-ins

Audacity supports almost all VST effect plug-ins on Windows including «shell» VST’s that host multiple VST effects.

To install new VST effects, place them in the Audacity «Plug-Ins» folder: Users\\ \\AppData\\Roaming\\audacity\\Plug-Ins

If you are installing plug-ins that come from Steinberg (including iZotope plug-ins) the installer usually automatically places these in its own plug-ins folder: C:\\Program Files\\Steinberg\\VSTPlugins (or C:\\Program Files (x86)\\Steinberg\\VSTPlugins on 64-bit systems).

If you are a privileged user and you need to install a plug-in for use by multiple user accounts on the same PC you may also install VST plug-ins to the Plug-Ins folder in the directory where Audacity is installed.

This is usually: C:\\Program Files\\Audacity or, C:\\Program Files (x86)\\Audacity on 64-bit machines.

All the directories where you can place VST plug-ins are searched recursively, which means that plug-ins that are inside their own folder in that directory should still be found by Audacity.>>

You can enable new VST effects in Audacity by using the Effect > Add / Remove Plug-ins. menu item. This opens the Plug-in Manager: Effects, Generators and Analyzers dialog where you can select and Enable the new effects then click OK to load them. Next time you launch Audacity the enabled effect(s) will be cached and you will not need to re-enable them.

The list of effects in the dialog will include any detected VST instrument (VSTi) plug-ins (such as synths) and any real-time VST effects that are capable of changing audio data while it is being written to disk. Neither of these are yet supported and they will not load even if you enable or re-enable them in the dialog.

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 is 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 Enable graphical interface and click OK . When you reopen the effect it will display a simpler tabular interface.

On Windows Audacity is a 32-bit application so will not see 64-bit versions of VST plug-ins, even on 64-bit operating systems.

If you experience a problem with a specific VST effect plug-in in Audacity, please contact us.

Installing LADSPA plug-ins

LADSPA has been superseded by LV2 and most if not all LADSPA plug-ins are ancient and are no longer maintained.

The LADSPA plug-in architecture was originally developed on Linux. Audacity supports LADSPA effects on Windows as well as GNU/Linux. You can download and install a set of over 90 LADSPA plug-ins for Windows. You can then choose which LADSPA plug-ins to enable in the Plug-in Manager: Effects, Generators and Analyzers dialog.

To add a new LADSPA plug-in, place it in the Audacity «Plug-Ins» folder: Users\\ \\AppData\\Roaming\\audacity\\Plug-Ins

If you are a privileged user and you need to install a plug-in for use by multiple user accounts on the same PC you may also install LADSPA plug-ins to the Plug-Ins folder in the directory where Audacity is installed.

This is usually: C:\\Program Files\\Audacity or, C:\\Program Files (x86)\\Audacity on 64-bit machines.

Then use Effect > Add / Remove Plug-ins. to enable the LADSPA effects and load them into Audacity, For details see Plug-in Manager: Effects, Generators and Analyzers.

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 Windows as well as GNU/Linux. There are not yet many pre-compiled LV2 plug-ins for Windows, 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:

• Users\\ \\AppData\\Roaming\\LV2 (or Documents and Settings\\ \\Application Data\\LV2)
• Program Files\\Common Files\\LV2 (or Program Files (x86)\\Common Files\\LV2 on 64-bit systems)

Then use Effect > Add / Remove Plug-ins. to enable the LADSPA LV2 effects and load them into Audacity, For details see Plug-in Manager: Effects, Generators and Analyzers.

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 Windows. 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.
