    There is no error message in Audactiy. It could be because of the formatting of the SD card. Formatted the SD with the standard allocation unit under Windows. I reformatted it with a 32kb cluster size. So far, the...

    The file size is well below the WAV file limit of 4 GB. For playback I use CoolEditPro and Audacity. The error does not always occur.

    Sometimes with long 384k recordings on exFAT, only part of it can be played. The file size is correct. If an hour is recorded, only 23 minutes, even 46 minutes, can be played. Sometimes it's right too.

    was probably misspelled by the translator, should be called "exFat".

    I was just wondering, it's so okay. Great, now also supports sdFAT. Accidentally plugged in the wrong SD from the AudioMoth and everything worked.

    A hidden Easter egg, how does the reinitialization of the display work? I disconnect this from the battery when recording. So I have much less interference at 23KHz and their harmonics.

    I found a bitmap on the SD card. Which key is used to take a screenshot.

    I used black screws, it looks a lot better too. In the new circuit board you could also activate the second operational amplifier in order to be able to record low-frequency signals with larger capacitors. At the...

    I have an infrared video camera. This records 1 second before a noise is detected. I connected this to the audio output of the detector. In "mode TE" it works wonderfully. If I then switch to "AutoREC" and there is...

    For the temperature sensor, I installed a copper sheet with the sensor drilled through on the outside. This is also how it measures the outside temperature. The GPS needs 27 mA for me. I had problems with the GPS,...

    Have a new device built up and equal resistors 150 ohms as the others for GPS and temperature sensor installed. It works wonderfully. If you like this, it could be included in the circuit diagram.
