I have an electric signal that I need to analyze. If I do a

these blurry sections automatically. Is there any way to analyze a
spectrogram window by window to detect something like this? Could
I
do this with fft somehow? Any help or similar files would be
great!
Thanks!!
Try changing window size in the specgram command
