132 - PowerSpectrum calculates a power spectrum from the input audio.
133 Actually, it doesn't do any work except converting from the cartesian
134 complex representation. The work of converting to frequency domain
135 is all done for it by the host or host SDK; the plugin just needs to
136 declare that it wants frequency domain input. This is the simplest
137 of the example plugins.
