Hello. So I thought the audiomoth has a directional microphone but it appears from a post below that its omni. But my question is what does this really mean since its housed in a box? Does it have a 180 degree field of hearing? Can it hear behind it at all where the batteries and cases may block sound? How do I achieve 360 field of hearing? Will i get this from one audiomoth or since the way the microphone is housed is it really only directional? I ask because I am working out detection distance for my species and so I need to work detection space from this. My species is a primate so I'm wondering if I face it up to the trees then do i get equal sensitivity in all directions?
