AU plugin support

Open nobodo opened this issue 9 years ago • 16 comments

Hi, AU plugin support would be great to have someday. I know it's not going to happen in near future, but one can always hope..

@nobodo do you have an example AU plugin in source code form that I could study? Which version of AU would be best to target?

Hello. Maybe this could help:

https://github.com/olilarkin/wdl-ol

I remember doing my first plugin test based on that. Also it seems that it's going through some refactoring at the moment, but I think the basics for AU could be learned from there if you happen to know any other plugin format.

is there opensource example AU plugins? something that implements the basic "gain" plugin as many plugin standards have...

Maybe this:

AU support has been started in the "au" branch. Builds a valid AU plugin (see Parameters example), but does not do any processing, parameter changes, state or include UI. Basically just the code setup to get something to build and show up as a valid plugin (which was already a big PITA)

Attaching files as proof :)

Wow! This is great news. One of the most common requests I get from Mac users is to release an AU version of my plugin; I never did have the gumption to ask for DPF to support AU.

Interesting code we can take ideas from https://github.com/blurkk/symbiosis-au-vst-2/blob/develop/Symbiosis.mm#L3163

https://github.com/WeAreROLI/JUCE/blob/master/modules/juce_audio_plugin_client/AU/juce_AU_Wrapper.mm This has pretty much everything we are missing in AUv2
