The visualizer is free, but is bundled with the iTunes software. You can, however, download the original from the Barbarian Group along with iTunes. Apple has since purchased all rights to Magnetosphere and the updated version can be found in iTunes 8. The Barbarian Group created Magnetosphere to add beautiful visualizations to iTunes on both Mac and PC.

WhiteCap is available as a free trial, which includes fewer features. WhiteCap provides you with on-screen menus to fully customize the visualizer. The visual effects continually morph and have real-time response to any audio played in iTunes.

There are literally thousands of combinations to create, which makes for an amazing visual experience. One of the first iTunes visualizers for Windows is WhiteCap by SoundSpectrum.
