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

  - AmplitudeFollower is a simple implementation of SuperCollider's
  amplitude-follower algorithm.
