Capturing any application audio output

Is is possible to use JUCE to write an macOS application/utility that will allow me to capture any application audio output, process it, and either save to disk and/or play via available audio output devices?

I’m not sure JUCE supplies the OS level functions required for this, but you could certainly write required the native code (although that might require kernel level code)… could you also just leverage an existing tool to route the audio to your app? like AudioBus, SoundFlower? I’m not a Mac specific developer, so I don’t actually know the details. :slight_smile:

Haven’t used it myself yet, but had my eyes on it for a while for a private project…
