==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 [http://www.linuxlib.ru/en/ladspa/ladspa.html LADSPA Plugin Developers' Documentation] and some [http://linux-sound.org/ladspa.html 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 [http://www.fosshub.com/Audacity.html/LADSPA_plugins-win-0.4.15.exe Windows] and [http://www.fosshub.com/Audacity.html/swh-plugins-mac-0.4.15.zip 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 [https://manual.audacityteam.org/man/effect_menu.html#add_ladspa this page] in the [https://manual.audacityteam.org/ 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 {{path|LADSPA_PATH}}. 
{{Hint|LV2 is an extensible, "second-generation" version of LADSPA that has a wider range of effects and can use LV2 synthesizer plug-ins as powerful tone generators. Audacity now supports LV2 effects. For details please see [https://manual.audacityteam.org/man/effect_menu.html#LV2_effects this page] in the Manual.}}
