I have been recording rat calls (which are in the ultrasonic frequency), but I am only just now realizing that the recordings I made only go up to 22k Hertz. I am usind the dodotronics 200k ultrasonic usb mic (which, as the name says should go up to 200k Hertz).

The mic is correctly selected in the program, but I cannot zoom out further than to 22k on the spectrogram and when I export the wav with maximum quality settings to analyze it in matlab with the deepsqueak program it appears that the audio also just cuts off at about 22k Hertz.

What am I missing here? I know of others who were able to work without problems with this exact setup. Please help!! Thank you!!
