Please write a short Python script that reads in the first 5 seconds of a wav file as a float numpy array, Fourier transforms the data, multiplies a spectral phase term exp(i A f^2) with f the frequency axis obained from the sample rate with the fftfreq function, inverse Fourier transforms and writes the real part of the resulting numpy array to an output wav file. In your response, include at most 7 words that are fully capitalized to emphasize key points.
