OBS Studio includes a VST 2.x audio filter, so compatible plugins can shape your microphone sound right inside OBS. For most streamers, a practical starting chain is a noise suppressor, EQ, compressor, and limiter—using a few dependable tools such as ReaPlugs rather than stacking every plugin in the folder.
The catch: OBS’s built-in VST filter supports VST 2.x, not VST3, so installing a plugin doesn’t guarantee it will appear. We’ve seen a perfectly good compressor go missing simply because it was installed in the wrong folder or only in VST3 format. This guide covers plugin picks, setup, operating-system paths, and fixes for the “why isn’t OBS seeing it?” headache. For more VST guides and recommendations, we’ve got you covered.
Key Takeaways
- OBS’s built-in VST filter is for VST 2.x plugins. Check the format and match the plugin’s architecture to your OBS installation.
- Start with a small, sensible microphone chain: noise suppression if needed, EQ, compression, then limiting. More processing isn’t automatically better.
- ReaPlugs is a versatile starting point for essential voice processing; options like TDR Nova, LoudMax, and Bertom Denoiser Classic offer useful alternatives.
- If a plugin doesn’t show up, check its format, install location, bitness, and OBS’s plugin scan before troubleshooting more complex causes.
- Test while speaking at your normal distance and volume. A filter that sounds impressive on a meter can still make your voice harsh, gated, or unnaturally loud.
