moodbar - moodbar - audio signal refinement architecture

Description:
The Moodbar is an algorithm for creating a colorful visual
representation of the contents of an audio file, giving an idea of its
"mood" (this is a rather fanciful term for the simple analysis it
actually does).  The Moodbar was invented by Gav Wood for inclusion in
the Amarok music player.

This package contains a plugin with elements that are used in the
moodbar analysis, and an application that actually does the analysis.

The plugin contains elements for performing forward and reverse
Fourier transforms to an audio signal, and a couple of example
analysis elements.  The included elements are:

  fftwspectrum:   Convert a raw audio stream into a frequency spectrum
  fftwunspectrum: Convert a frequency spectrum stream into a raw audio stream
  spectrumeq:     Scale amplitudes of bands of a spectrum
  moodbar:        Toy analysis plugin based on Gav Wood's Exscalibar

The application is called moodbar.  Its syntax is:

    moodbar -o [outfile] [infile]

where [outfile] will contain the moodbar data, and [infile] is an audio
file that gstreamer can decode.
