Stream audio data between two AudioProcessorGraphs

Hi,

I am using two AudioProcessorGraphs in my Juce Application to both process two audio streams individually and handle multiple audio devices. That is already working fine.

Now I would like to send an audio stream from one AudioProcessorGraph to another, e.g. to be able to use this as a sidechain input. At the moment, I’m not sure how best to do this, since the two processors have individual AudioIODeviceCallbacks, Threads, etc. Is there a best practice or recommendation on how to do this?

I would appreciate any advice! Thanks
