dll plugin in Linux

Hello. I want to know how to use dll plugins (for ex., ModernDynaKiller.dll). Tried to put it to some locations as advised, but program does not see it. Linux Debian 9, Audacity 2.1.2.

Dll plug-ins are for Microsoft Windows.

VST effects are supported by Audacity on OS X and GNU/Linux, but relatively few are available on Mac (due to Apple’s competing Audio Units technology) and even fewer on Linux.

On GNU/Linux, 32-bit systems will have 32-bit versions of Audacity which won’t see 64-bit VST plug-ins. 64-bit systems will have 64-bit versions of Audacity which will see 64-bit VST plug-ins but won’t see 32-bit plug-ins.

VST plug-ins for Linux must be made for Linux. VST plug-ins built for Windows only work on Windows. It’s very unusual to find VSTs built for Linux, they are very rare, but there are loads of LADSPA and LV2 plug-ins, and Audacity’s own “Nyquist” plug-ins are fully cross-platform.
