I am starting a bird vocalization monitoring project with an Audiomoth, in Los Angeles and I'm looking for assistance with how to do the audio processing on my computer. Can someone help me find the right resources?
Thanks

Hello!
I’m experiencing an issue with around 15–17 AudioMoth devices. They can be configured without any problems initially, but after some time the configurations are lost and the devices revert to their default settings.
I’ve already tried replacing the batteries, reflashing the AudioMoths, and using different SD cards, but the problem still persists. What could be the cause of this, and are there any additional troubleshooting steps you would recommend? Could this indicate an issue with the flash memory, meaning the devices might be defective?
Thanks in advance!
They last about two months, and then NONE of them enumerate anymore. I have debugged in Linux and Windows - they are not being recognized. I have tried re-zapping the firmware - nothing. LEDs work.
Should I just throw these away?
Hi Gil,
It's very unlikely that all four have failed. The most common reason for no communication between the AudioMoth and the computer is that the USB cable is a charging cable and has no data lines. The first thing to do is to double check that the cable allows communication with other devices (or try a few cables).
If that doesn't fix it, can you describe in more detail what happens when you try to reflash the firmare. Is the device recognised by the Flash App? Alex
Hi folks. Just looking for clarification/confirmation that the audio trigger feature can be used on audible frequencies and not only ultrasonic? Thanks in advance.
Yes, you can use amplitude and frequency triggering at any sample rate and detect any frequency. If you some examples of un-triggered recordings, you can upload them to AudioMoth Play (https://play.openacousticdevices.info) and experiment with the settings. Alex
Hi Mohamed, I don't think this problem has been described before. It's maybe possible that the user page of the flash memory is being corrupted, but it seems unlikely that only one page of the flash would be affected and not others. Seems strange that so many devices are affected. The mechanism in the firmware is that each time the AudioMoth powers on from a powered-off state, it checks the firmware version and description in the user area of the flash against the current version in the firmware and replaced the configuration in the user area of the flash with the default one if they do not match. This would return the configuration to the default setting. When do you notice that the configuration has been reset? What make and model of SD card and batteries are you using? Alex
