How to Use an iTunes Visualizer As a Screensaver


The iTunes application's high-resolution visualizer is a continuous animation that responds to the audio frequencies of songs played in the media library. Although the animation cannot be used as a screen saver by default, you can use the full-screen visualizer to override your screen saver's activation, ultimately providing the same functionality as a screensaver. In addition, if you have access to Apple's Developer Tools, you can set up an iTunes Visualizer to become your computer's screen saver.

Things You'll Need

  • Xcode (Apple's Developer Tools)

Full-Screen Visualizer

  • Disable your screen saver settings. On the Windows 7 operating system, open the "Appearance and Personalization" menu in the Control Panel. Click the "Personalization" tab and select "Screen Saver." Select "(None)" in the screen saver menu. If you are using the Mac OS X, open "System Preferences" and select "Desktop & Screen Saver." Click the "Screen Saver" tab and drag the slider to "Never."

  • Launch iTunes. Double-click a song in the library to begin playing the track.

  • Press Ctrl + T (or Apple + T on a Mac) to activate the visualizer.

  • Press Ctrl + F (or Apple + F) to make the visualizer fill the screen. The visualizer's constant animation will act as a screen saver while your computer is not in use. Press Esc at any time to exit the full-screen visualizer.

Developer Tools (Mac Only)

  • Download an iTunes visualizer.

  • Copy the visualizer file to your "Screen Savers" folder in the Library directory on your Mac computer.

  • Launch Quartz Composer. Click "File" and "Open." Open the visualizer file in your "Screen Savers" folder.

  • Click the "Editor" menu and select "Edit Protocol Conformance." A new prompt will open.

  • Uncheck the "Screen Saver" option.

  • Click "File" and "Save" to update the visualizer file. The full-screen visualizer will now be activated in place of your default screen saver.
