Hello!
I looked around for a post on this but couldn't find anything on the forum. Some of my audio files have a mirror image of the lower frequencies (below 12 kHz) at higher frequencies (above 12 kHz) - see screenshots attached. The audio is fine, I can identify the birds of interest from the audio clip. However, I imagine I can't use this data for any kind of spectral analysis.
Why do you think is happening?
Thank you!
I am seeing this for my AudioMoth recordings at some of my sites as well, @Pooja Choksi - did you find out any more information? Despite using the same configuration for all of my AudioMoths, I am only seeing these mirrored sonograms for some of them. Using RFCx Arbimon to visualize currently.
