There’s binaural localisation from phase and amplitude differences, but importantly also monoaural cues from frequency response. Your pinna act as a set of directional filters - which is part of why some binaural recordings can quite literally feel as though they’re in your head. What’s interesting with this is that while you can’t get those directional filters, you could use a system like this to provide 3 or more ‘sensors’ (eg the chip packet demo) within a scene and isolate signals the same way as an array mic.
