How to make AVAudioEngine with nodes persistent using NSKeyedArchiver?

Question

Is it possible to use NSKeyedArchiver to save an AVAudioEngine, including all its nodes and connections, to a file and later restore it using NSKeyedUnarchiver?

If not, would Core Data or another API be more appropriate for achieving this?

I’ve searched Apple documentation and other resources online but found little discussion on this topic. Is this approach either so straightforward that it’s rarely questioned, or am I conceptualizing the task incorrectly?

Thanks in advance to anyone who can provide guidance!
