You have an app that receives live audio (as far as it's concerned), processes it, and sends it out live. That by itself says that you have some non-trivial routing.
For a made-up example, which might be more complex than what you have:
Code:
+---+ +---+
+------>| C |------>| E |-------+ +---+
+---+ +---+ | +---+ +---+ +------>| | +------+
| A |------>| B |-------+ | G |------>| Etc. |
+---+ +---+ | +---+ +---+ +------>| | +------+
+------>| D |------>| F |-------+ +---+
+---+ +---+
F, here, doesn't see what C is doing, and E doesn't see what D is doing. G sees everything, and everything sees A and B.
So what's your routing? Answer that accurately, and you also have the answer to your question.
