It costs ~$1,000 so you'd probably rent it if you're only going to use it once, but it's a neat gadget.

You can also build one pretty cheaply and simply with the miniDSP UMA 16: https://www.minidsp.com/products/usb-audio-interface/uma-16-...

Oh, was gonna post a comment about this, I actually bought just last week their USBc version (Fotric Sonic 3), on eBay, for around $700. Works quite well, it has 64 mic array, I think it would be tough to replicate it to this level.

Lmk if anyone has any questions about it! It’s android-only, but I’ve gotten an agent to write a Mac version of it though haven’t tested yet.

		Are you able to gather the multichannel recordings off the device? I’ve often wondered if you could do that, then replay a video while focusing on specific parts of the scene. Kind of like a virtual stethoscope.

Great thing for tool checkout/rental at a makerspace!

Does it work for infrequent sounds? The sound might for example come in the middle of the night for two seconds, loud enough to wake one up, then go away. If I leave it on, can it do continuous recording and max or threshold-based capture?

		That should work. You could always have Claude Code run the server itself and explain to it the rough parameters of the sound (two seconds, late at night) - then let it listen for hours and occasionally tweak its own configuration to try to better capture what's happening. In my case it identified that the likely beep was about every 62 seconds pretty quickly - then I confirmed that one of the recordings was the mystery sound and it locked in from there.
