Missing features - Audacity Support [windows]
The problem is that there is the Nyquist plugin interface which is native to Audacity and which has a Forum of its own Nyquist - Audacity Forum. So that cuts across a “Plugins” forum.
If you have a request for a native Audacity plugin, please post the request at Adding Features to Audacity.
What plugin format are you interested in? See Missing features - Audacity Support.
