pectroGraph is a visual plug-in for iTunes for Mac OS X. Visual plug-ins were introduced in version 1.1 of iTunes. The plug-in started life as a simple modification of Apple's iTunesXPlugIn sample code, but has grown beyond that in newer versions. Of course it's completely free!
The plug-in displays a plain spectrogram (hence the name) of the music. A spectrogram is a graph of the frequency content of a sound in function of time. The left channel is plotted in red, the right channel in green. This means that a mono sound will show up in pure yellow (because in RGB space, red green = yellow).
I made this plug-in because I needed something which represented the actual spectrum of the sound as realistically as possible.
