Unformatted text preview: You can hear what they sound like using the wavplay() or sound() command, make sure to specify a sampling frequency such as 22050 Hz. Plot the spectra for the three files, and be sure to title each plot with which sound is being analyzed. Remember, the fft() will return a complex result, so you can use the abs() function to compute a magnitude spectrum, which will contain only real values. What do you notice, if anything, about the three plots? Comment on the harmonic content of each plot. Considering the Fourier transform of a sinusoid, do your results make sense?...
