"One should have set up a recorder with half an hour pre-rec all the time"
Got me thinking about looking into such a recorder. There's a whole bunch of car dash cams out there that start recording video either based on motion or in a continuos ring cycle buffer recording mode. (Apparently these dashcams were the main source of these meteor videos to begin with.)
I would love to have something like that for audio field recordings. These dashcams tend to have pretty poor audio fidelity. Does anyone know of any portable audio recorders with a cycle buffer mode or remote control record option (to trigger via a motion sensor)?
I'm aware of the recorders with the pre-buffer option. I'm more thinking about a recorder that's continuously recording to the SD card, but instead of stopping when out of room, it starts to overwrite the beginning of the file.
