Spectrum is a hi-tech graphical sound analyzer, that displays a live spectrum on the screen when you play music from the radio or sing along to your favorite tune. It works by picking up sound from the microphone and then displaying it graphically on the screen. It is comparable to displays on high end sound systems, but with the benefit of being able to carry it around with you on your iPhone.

Put it next to your stereo system and watch the cool graphics dance to the music, it's mesmerizing to watch!

Best performance on iPhone 3G. May be slower on the older iPhone.
Not compatible with iPod Touch.

(Note: Spectrum does not display music that is playing on your iPhone. It works with other sound or music that is picked up through the microphone.)
