I am doing fieldwork with a few AudioMoths but unfortunately there is an issue with my recordings. It seems that after a few minutes or sometimes even after one minute the recording stops and the files show that the time switched to 1 January 1980.
I have just changed the batteries, I get four flashes so that shouldn’t be the issue. The sd cards are empty so that can’t be it either. Any ideas?
Make sure that you reformat the SD cards between deployments rather than just deleting the files as often deleting them just moves them to a hidden folder rather than actually removing them from the file allocation table. I assume that the files, other than the first one, are zero size? If so, I think reformatting will fix the issue.
Are the files the correct size and readable? If the file sizes are not readable, could you share a screenshot or copy the WAV comments on WAV file 2022034_094500.WAV? In the metadata AudioMoth will state a reason for files ending early.
