Well I'm not doing anything smart with this but perhaps readers will be interested; New Zealand bird song recorded at dawn each day, with a remote solar powered pi. Here as an RSS feed or ready to go on Spotify

I spent a couple months last year trying to figure out how to commercialize this tech and never really landed on anything that felt venture scale. There’s lots of cool stuff happening in the research space though, and I remain convinced that it is only because of our natural bias towards vision (it being our most conscious/directed sense) that this technology is slightly behind CV.

If anyone ever wants to start a machine listening company that isn’t focused on speech or music come find me and I’ll share all of my notes/competitive research/etc.

What frequency ranges are needed to be able to hear this stuff? I would love to mess around with this using my tomato plants and a rasp pi or something just to see if I can hear anything when they get dry.

I think plant emissions are up in the like 40-80khz range? You can get consumer specialty mics that go up into the 50s for sure, but I'm not super well-versed on the capture options in that freq range.

I’ve been fascinated with this stuff, since I was a college student in Bellingham, Washington, armed with a field recorder, and surrounded by Wild woods. I haven’t given thought to machine listening company but I’m certainly interested in what you know.

Some device that I can put in my garden and will send status reports on bird kinds and the state of the plants (the article mentions tomato plants giving something audible if dehydrated) would be really awesome. Especially in relation to weather, time of day, day of the year, etc.

The birders are super ahead of the curve. Check out this Rpi implementation of BirdNet: https://github.com/mcguirepr89/BirdNET-Pi

Some other options for low-cost backyard sound/biodiversity monitoring are:
