Hi all, I programme my Audiomoth to record overnight (for nocturnal bird calls) and after five nights working absolutely fine, it then begins to fail, by recording seemingly random small files (as opposed to the 29m 55s files i've programmed it to record). I've tried it with two different Audiomoths, different batteries, SD cards (I use a 128gb that should last for many weeks), and I've made sure it's fully updated. I've screenshot the details, and also an example of what happens to the file sizes after five nights.
Thanks in advance for any help!
Mark
Thanks Andy, I'll bear that in mind!
Thanks Andy - will do. I'm using new-ish Duracell rechargeable 2500mAh batteries and a 128gb Sandisk Ultra SD card
No problem, did you save the data anywhere? What make and model batteries and SD card are you using? If it is deleted, I'd recommend reformatting the SD card and redeploying the device with new batteries.
Can you double check that there were any AudioMoth Wav files on the folder you ran the Summarise tool on? You should be seeing a summary of the 5 days of AudioMoth data you collected.
Thanks, Andy. I've just done that and it brings up the spreadsheet, which (but for the headers) is blank...
Connect your SD card to your PC so you can view the recordings made on the AudioMoth. Then you'll need to select the folder that the wav files are located, I'd select the SD card as the folder. Then just click Summarise Files and the .csv file will be saved to the SD card.
Hi Mark, Smaller files can be a sign of low battery level or an SD card becoming full (or a well used unformatted SD card being used). What type and model of battery and SD card are you using? Is the SD card reformatted before each deployment? If you delete files on SD cards, they often aren't actually deleted, just hidden, and the file allocation table gets filled up over time. Could you run the "Summarise AudioMoth Files" (see image) tool from the configuration app menu and share the resulting .csv file? This should give you an indication of what causes the smaller files, e.g. battery level or SD card error.
