Why write in French and English on the Spanish Forum? 
That seems to minimise the chance of anyone answering. 
I assume you mean ladspa-swh which is Steve Harris’s LADSPA plug-ins set.
A PDF is only a document, you cannot open a PDF in Audacity.
If you want the plug-ins themselves, see http://audacityteam.org/download/plugins .
