So you have some downloaded. How to get them into OBS? OBS won't let you define the folder easily. Just install them into one of these: Windows: %ProgramFiles%\Steinberg\VstPlugins\ %ProgramFiles%\Common Files\VST2\ Mac: /Library/Audio/Plug-Ins/VST/ ~/Library/Audio/Plug-ins/VST/ 6/

Now when you go into OBS you can add a filter to the source for your mic (this works on video as well for that matter) Right click the audio source and go to filters. Add a VST 2.x Plug-in filter. Name it whatever VST2 you're going to use. Choose it and click Open Plug-In interface. 7/
