However, after the uninstallation of the previous versions of Audacity(1.2, 1.3 Beta )Unicode), 2.0.4), my new 2.0.5 installation doesn’t show the LADSPA plugins(recommended for Windows by the Audacity website) I moved to the C:Program FilesAudacity2.0.5pluginsLADSPA folder. Nor does it recognize the VST DLLs I placed on the C:Program FilesAudacity2.0.5VST folder, the wiki recomends.
This is expected. The LADSPA plug-ins should be in the root of the Plug-Ins folder, as described in the Manual: Audacity Manual .
Personally I think Audacity should look in a LADSPA folder in its installation folder or in a LADPSA folder in its Plug-Ins folder, but that is how it is at the moment.
Audacity will see 32-bit VST effects there.
Did you go to the Effects Preferences, put a tick (checkmark) in the box “Rescan VST effects next time Audacity is started”, click OK and restart Audacity?
