  Do human ears resolve sound in more than one dimension? I've always considered that, per ear, we only get a sequence of compressions and rarefactions on the ear drum, that other aspects of hearing are through combination or 'cheating' (skin sensitivity and such). So, would it matter?

    No, but a thing vibrating in any dimension will still produce sound waves.

    You can pinpoint with your two ears where sound is coming from, fairly well. Takes some training, of course. That said, I get the impression this is more complicated than the autocorrelation of multiple sensors?

    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.
