Plugins: VST3, LV2, LADSPA & FFmpeg
Add effects and extended format support to Audacity on Windows. Learn where to install VST3/LV2/LADSPA/Nyquist plugins and how to enable FFmpeg.
At a glance
- Use 64‑bit plugins with 64‑bit Audacity.
- VST3: C:\Program Files\Common Files\VST3 (default scan path).
- Enable/scan in Preferences → Effects.
- Install FFmpeg to import AAC, AC3, AMR and more.
VST3 on Windows
Place plugins in C:\\Program Files\\Common Files\\VST3 or C:\\Program Files\\VSTPlugins. In Audacity, open Preferences → Effects to rescan and enable.
LV2 & LADSPA
Install to your chosen plugin folder and add its path in Preferences → Effects. Then rescan and enable the plugins.
Nyquist
Nyquist scripts (.ny) can be placed in Audacity’s scripts/plugins folder. Enable them from the Effects list after scanning.
FFmpeg setup
Install a 64‑bit FFmpeg build, then in Audacity go to Preferences → Libraries, click Locate, and point to the folder with avformat/avcodec/avutil DLLs.
Real‑time effects
Many VST3 and LV2 effects support real‑time adjustment. Use the Effects Rack to tweak parameters while playing audio.
64‑bit only
Use 64‑bit plugin builds. 32‑bit plugins are not compatible with 64‑bit Audacity.
Troubleshooting plugins
- Plugin not listed: rescan in Preferences → Effects; verify 64‑bit build.
- Crashes on load: remove the plugin, restart Audacity, check for updates.
- Missing UI: some VST may show generic controls; try a different version.
- No audio: bypass effects to confirm; check effect order in the rack.
