Check out the LM 3514 (or 3515 or 3516 I'm not sure which)from National semiconductor. They are ten segment drivers that display in dB with just a few resistors and 10 LEDs. If you want to do just one set of LEDs per channel it is pretty easy, if you want to do different LEDs for different frequencies like some EQs it will be a little more complicated.

Thanks for correcting me on the part number, I didn't think I had the right one but my data book from National was nowhere to be found last night.
