Let’s say I have ACX-Check.ny sitting comfortably on my desktop. I want to install it in Audacity 3.3.3. How? I can’t make sense of the manual and the graphics don’t tell me enough. I think it’s leaving parts out or assumes I know more than I do.
I seem to be missing the step where I point to ACX-Check.ny and say “This One.”
Click on “Browse” then navigate to the desktop to select the plugin.
Then press “Open” on the file browser, (as if you were opening the Nyquist file).
That takes you back to the Nyquist plugin installer window,
where you then press “Apply” …
In addition to Trebor’s answer, note that recent versions of Audacity have to be closed and restarted after installing a plug-in. On restart, Audacity will automatically enable the plug-in (before restart, the plug-in does not show up in the Plugin Manager).
