Audio output display

Hi all ...
i want a circuit iagram or a reference for an audio output display..
i want to make a circuit like for example winamp graphic equalizer output with LEDs .
this circuit should has 4 frequency range and in each frequency range i want to show amplitude with LEDs like winamp or jetaudio equalizer output display .4 culomns of led each of them for a frequency range.
thanks for your attention

Audio output display

In my opinion, u can do it this way.
1)design circuit using bargraph LED driver like LM3915 to drive 10 LEDs. (the circuit is with the PDF datasheet)
2)design 4 filters with the range that u want... (mostly RC filter)
3)connect your audio output(assume single) to the 4 filter input, then connect each filter output to the LED bargraph driver.

there should b a lot of such hobbist circuit around the net... (",)
