Native VST3 audio effects for OBS Studio on Windows — isolated plug-in hosting, vendor GUIs, automatic discovery, state restore and dry fail-open recovery.
Why this project exists
OBS Studio’s built-in VST filter does not provide VST3 hosting. Many current studio EQs, compressors, restoration tools, reverbs, saturators, limiters and mastering processors are distributed primarily, or only, as VST3s.
OBS Safe VST3 Host adds two OBS-native workflows on Windows:
- VST 3.x Plug-in — a simple one-effect filter for the common case.
- VST3 Rack — a separate isolated serial multi-effect chain with a dedicated graphical Rack Editor and broadcast-oriented master console.
Third-party VST3 runtime code, vendor editors and plug-in scanning are deliberately kept outside the OBS process.
