Spectrum Analyzer
LED Spectrum Analyzer is a visualizer plug-in for iTunes on Mac OS X. It creates a spectrum analyzer display in the style of a typical hi-fi system, using bar graph displays that emulate LED’s or similar electronic display technology. The bar graphs can show linear or logarithmic levels, and also the peak value of the signal in a number of frequency bands per audio channel. In addition it can show the overall level on a pair of VU (Volume Unit) bar graph meters. Numerous options are included to make a colorful and interesting display.
What do I do with Spectrum Analyzer?
Copy or move the Spectrum Analyzer file into the “iTunes Plug-ins” folder within your home folder hierarchy. The correct location is ~/Library/iTunes/iTunes Plug-ins, where “~” means your personal Home folder. If the plug-ins folder doesn’t already exist, simply create it in the Finder, making sure it’s named correctly. Within iTunes, the visualizer can be opened using the “LED Spectrum Analyzer” menu item in the Visualizer menu. You need to Quit iTunes before moving this to the plug-ins folder to ensure that it loads it next time it runs.
How do I use Spectrum Analyzer ?
Start some music, click the visualizer button, sit back and enjoy the blinking lights of Spectrum Analyzer! Once you get bored with that, you might wish to fiddle about with the settings. In iTunes 7.0, the visualizer button has been replaced by the Turn On Visualizer menu (command-T) under ‘View’.
