Announcing Inter-App Audio (IAA) support for standalone plug-ins in JUCE 5

Audio Plugins

I’m afraid IAA was deprecated by Apple in 2019, and as such, whilst we’ve kept IAA functionality within JUCE, we’re no longer providing direct support for it.

IAA-like functionality is now available using AUv3 audio units. I recommend switching to a plugin project and enabling the AUv3 and Standalone formats.

There’s not a simple set of steps to convert an application project to a plugin project. I recommend looking at the AudioProcessor class to understand the functionality that’s available (start with prepareToPlay, processBlock, and createEditor). From there, you should get a reasonable idea of how to call your audio processing code and editor code from a new AudioProcessor implementation.
