write some code to open up a WAV format audio file and figure out how to populate an array from the payload ... feed this floating point array into a FFT call which will return a new array where each element contains a complex number ... iterate across this new array and for each element calculate the magnitude of that complex number then plot these magnitudes ..

The FFT function returns a result equal to the complex, discrete Fourier transform of your float array. The result returned by FFT is a complex array that has the same dimensions as the input array. The FFT algorithm will then return a complex spectra that will give the amplitude and phase at a series of equally spaced frequency points.

The "Fast Fourier Transform" (FFT) is an important measurement method in the science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems.

FFT on our Audio signal. Now that we have seen how this FFT algorithm gives us all the frequencies in a given signal. let’s try to pass our original audio signal into this function. We are using the same audio clip we loaded earlier into the python with a sampling rate = 16000.
