The end result is a score of how important each frequency range is, from low pitch (i.e. bass notes) to high pitch. Each number below represents how much energy w…

…rier transform. It breaks apart the complex sound wave into the simple sound waves that make it up. Once we have those individual sound waves, we add up how much energy is contained in each one.

We do this using a mathematic operation called a Fourier transform. It breaks apart the complex sound wave into the simple sound waves that make it up. Once we have th…
