           Summary: New plugin: fftw-based Fourier transform + toys

        OS/Version: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

     GNOME version: Unversioned Enhancement
   GNOME milestone: Unspecified


This is a patch to the CVS HEAD of gst-plugins-bad.  It adds a new plugin,
"fftwspectrum", with four elements:

  * fftwspectrum: use fftw to convert a raw audio signal into a frequency
spectrum (in chunks) using a discrete Fourier transform
  * fftwunspectrum: the inverse of fftwspectrum
  * spectrumeq: a multi-band equalizer that operates on frequency spectra
directly
  * moodbar: a toy analysis element based on Gav Wood's Moodbar code for Amarok

The main reason I wrote this plugin in the first place was to revive the
moodbar code in Amarok, as the Exscalibar library on which it used to be based
is now unmaintained.
