then select "Plot Spectrum . " It opens up a window that displays the Power Spectrum
of the audio over that region, calculated using the Fast Fourier Transform . The graph
represents how much energy is in each frequency . As you move the mouse over the
display, it shows you the nearest peak frequency . This window can also display other
common functions that are calculated using the Fast Fourier Transform, including
three versions of the Autocorrelation function . The Enhanced Autocorrelation
