You are given two short audio sounds (50001 samples per sound) sampled at 44100H corresponding to sounds from two different sets of mechanical gears.
a) Develop a technique that will use the Fourier Transform to classify each sound as Gear1 and Gear2. Make it flexible so that the audio volume of the recordings can change without incurring in a misclassification. Consider that Nw is the 50001 samples, that is, you only have two examples
