Given this x (frequency) an y (amplitude) spectrum analysis of frequencies: https://postimg.cc/34vc19CD
How can I determine the dominant frequencies? How would I iterate through the numpy array to find frequencies (x) that show up more often than others with some sort of cutoff?
Also, how could I group the dominant frequencies with some sort of range, such as frequencies between 30 Hz - 70 Hz are dominant, etc.
