Troubles to downsampling AudioMoth and HydroMoth WAV files and folders

Hello. I have concerns when downsampling AudioMoth WAV files from 250 kHz to 48 kHz. The processing is very simple and quick for some files and folders, but for others, I cannot execute the process because the files are not recognised.

In brief, the configuration App does not recognise many of my AudioMoth or HydroMoth files and folders. After selecting them it says "No Audiomoth WAV selected".

Any help would be very welcome! thank you

Hi Alex, I have moved some files and folders to the desktop and other hard disks but the problem persists. For some folders/files, the App does not recognise the recorded audios. I have also checked the properties of these audios, and they are the same as the downsampled ones.

I do not understand.

I have also changed the names but it does not work either.

For your information, my computer has Windows 10, and the recording devices are various 1.2.0 AudioMoth & 1.0.0 HydroMoth and the Firmware-Basic used is 1.11.0.

Next week I will try it with another computer.

Many thanks for your help,

Lydia

This seems very strange and I'm not sure what can be going wrong. Can you confirm which version of the Config App you are using? It should be version 1.12.1.

When you say 'the App does not recognise the recorded audio' - what does that mean? If you select one individual file, does the app say 'Found 1 AudioMoth WAV file' in the 'Downsample AudioMoth WAV Files' window (as below)? If not, the file must have a filename that the app does not recognise as having come from an AudioMoth. If the app shows the message but then fails when downloading, there is probably some additional data in the file. Sometimes this comes from opening the WAV file in another audio editor app which then silently adds metadata to the original file.

Do you have an example of two files that when placed on the desktop, one will downsample and not the other? If so, could you share those files somewhere.
