Hi there, I have been using my audiomoth successfully to record bat calls from sunset to sunrise here in the UK. The audiomoth is configured to record for 15 seconds periods followed by a 5 second pause. All was going well until recently. Visually scanning the wav files using kaleidoscope after a nights recording reveal that the files are getting progressively shorter. Although configured to 15 seconds, last night the first file (at around sunset) recorded for 6 seconds and gradually the periods reducing to zero seconds by about 5 am. The same thing happened the night before, the actual recording period started at 15 seconds (at sunset) but reduced during the night to a recording period of less than a second. Has anybody got any thoughts what the problem might be? I have tried reconfiguring the AM. Perhaps I should re load the firmware?
