Webin general a complex valued vector even if x is real valued, so it is usual to plot both the magnitude j^x(k)j and phase arg(^x(k)) on separate graphs. The elements in the ^x vector are coe cients for the frequencies f = 0;1=N;2=N;:::;(N 1)=N. However, notice that the high frequencies are equivalent to low negative frequencies due to aliasing. WebSpectrograms are a means of visualizing the energy and pitch of a particular sound. In this example of a blue whale call, the spectrogram (upper image) plots time (horizontal axis) versus frequency (vertical axis), with warm colors representing high acoustic intensity.
