Unable to load JUCE plugins to Audacity


So I’m trying to load a simple delay JUCE plugin to Audacity. I have compiled everything (32-bit) and the Delay.vst file automatically popped in ~/Library/Audio/Plugins/VST. There is also the Delay.component file which I copied to ~/Library/Audio/Plugins/Components, although I’m not sure whether this is necessary. In any case, Audacity detects that there is a new VST in the folder, but it simply doesn’t show it in the Effects menu. Anyone encountered this issue before?

I am running on OS 10.10 (Yosemite) and the latest version of JUCE and v2.1.0 of Audacity (also tested on 2.0.2). Installed audacity using the dmg file.

Kind regards,


2.1.0 and especially 2.0.2 are obsolete.

In the current Audacity 2.1.2 which you can obtain from http://audacityteam.org/download/mac you would use Effect > Add / Remove Plug-ins… to enable the VST effect. Please see http://manual.audacityteam.org/o/man/effect_menu.html#vst.

In 2.1.0 you would enable the effect in the dialogue that appears before Audacity launches. Check in any 2.x version of Audacity that you have VST effects enabled in Effects Preferences.

Does your effect appear in GarageBand?

If it does, please use 2.1.2 then attach ~/Library/Application Support/audacity/pluginregistry.cfg. Attach or post the effect if you are free to do so.


Hi and thank you for your detailed answer.

I also can’t see the effect in Garageband, so I’m assuming the problem is in the effect.
I also tried in Audacity 2.1.2, and it seems that whenever I enable the effect, it automatically switches back to “New” rather than “Enabled” and it doesn’t show it in the effect list.
The effect is in https://www.dropbox.com/s/cb79tr20ugp1bq1/Delay.zip?dl=0 and the cfg file is attached. Would you be able to have a quick look at it?

Sorry, if it does not show in GarageBand it is assumed faulty and not an Audacity bug. None of us here are VST plugin developers.

If you post the Windows DLL I can check if it’s usable there, but that’s all I can do.
