Viewing and Downloading Plug-ins

  • To view the plug-in code:
Left-click the "View/Download" link. Nyquist plug-ins are plain text files with a ".NY" file extension. Most good web browsers are able to display the code as text.
  • To download the plug-in:
Right-click the download link and select "Save Link As..." (Firefox/Chrome), "Save As..." (Internet Explorer), "Download Linked File As..." (Safari). Other modern web browsers usually have a similar right-click option, except for Microsoft Edge. For further information, please see the documentation for your web browser.
Alternatively, view the file by left-clicking the link, then use the "Save" command from your web browser's File menu.
Warning icon Microsoft Edge only supports right-click "Save target as" as from the "1511" Windows 10 update (build 10586.3). In older versions of Edge you can use the "More actions" button ··· top right then "Open with Internet Explorer".

Installing Plug-ins

To install a Nyquist plug-in, place its ".NY" file in the Audacity "Plug-ins" folder. In Audacity 2.1.1 or later, use Effect > Manage... or Effect > Add / Remove Plug-Ins... to open the Effect Manager. Select the plug-in(s) you want to install, then click Enable and OK.

  • On Windows and OS X the "Plug-Ins" folder is in the directory where Audacity resides - usually C:\Program Files or C:\Program Files (x86) on Windows or the "/Applications" folder on OS X.
  • On Linux, the "plug-ins" folder is in usr/share/audacity if you installed an Audacity package supplied by your distribution, or usr/local/share/audacity if you compiled Audacity from source code. Optionally a "plug-ins" folder can be created in your home directory thus: ~/.audacity-files/plug-ins (you can also call the folder "plugins").

For further details please see in the Manual.

In obsolete versions of Audacity there is no Effect Manager. Restart Audacity after placing the ".NY" file in the "Plug-ins" folder.

Warning icon More recent Nyquist effects may not appear in old versions of Audacity or may not work correctly. The current version of Audacity is available on the Audacity website.

List of available Plug-ins

Warning icon Feedback and bug reports:
  • All new plug-ins added to this list are tested in the Audacity 2.x version current at the time, but many of the older plug-ins are still in need of testing.
    • Please report any bugs to the Nyquist section of the Audacity forum (or alternatively to our feedback email address) so they may be fixed.
    • Some Nyquist plug-ins are unsuitable for processing long audio tracks. If a plug-in causes excessive memory use and causes Audacity to freeze or crash when used on long tracks, please let us know so that we can either limit the plug-in to short selections or add a note to the plug-in description so as to warn other users of the possibility.
  • Please also let us know which plug-ins you like and find useful as that will help us to develop the types of plug-ins that users want.
