My recent long term remote recording work has been done with commercial digital recorders and lavalier microphones, powered with a USB lithium battery pack. The recorder and battery are placed
in nested zip loc bags, with the microphone cord routed through a gap or a hole taped closed. For indoor use that packaging probably won’t be necessary.

Typical use is a 32GB flash capacity, and so the recording duration depends upon your required sampling rate, resolution, and whether you can use perceptual audio coding. Good luck! Rob From: AUDITORY - Research in Auditory Perception <AUDITORY@xxxxxxxxxxxxxxx>

Hi Sam, you could use our autonomous recorder, based on RaspberryPI. Here you can find all the details and code, together with a paper where we run some evaluations in the field. 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 rather well, and is not too expensive. But you can of course also use other microphones with ¼ jack connector and max 5v
power requirements. If you need 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 connectors and phantom power. I hope this helps! best
From: AUDITORY - Research in Auditory Perception <AUDITORY@xxxxxxxxxxxxxxx> on behalf of Norman-Haignere, Samuel V <Samuel_Norman-haignere@xxxxxxxxxxxxxxxxxx> I’m interested in making continuous recordings of the sound in a room for a week at time. I’m wondering if anyone on this list has a suggestion for:
Thanks in advance! My best, Sam |
