Moodbar package --------------- The moodbar package should be installed in the same prefix as gstreamer -- please see the INSTALL file for instructions on how to configure the moodbar package correctly. 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 Gavin Wood and Simon O'Keefe for inclusion in the Amarok music player. This package contains a GStreamer 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.
