Here you can f= ind all the details and code, together with a paper where we run some evalu= ations in the field. https://sarabsethi.github.io/autonomous_ecosystem_monitoring/ Of course in your case you can power it using the mains rather than having = to use solar panels, and you don't need to stream them through the network = but can keep them in a large SD card. By default they'll be segmented in 1-= hour chunks, but you can change that in the code quite easily. We have used this with the Rode SmartLavPlus mic, which is omni and works r= ather well, and is not too expensive. But you can of course also use other = microphones with =BC jack connector and max 5v power requirements. If you n= eed more (e.g. 48v phantom power) then you'll need to get a dedicated audio= interface for the RaspberryPI...there are a few USB ones with XLR connecto= rs and phantom power.
