[sci.electronics] Building a Spectrum Analyzer

I am thinking about building a ~16 band spectrum analyzer.  I was going
to use a PLL to sweep the audio spectrum through a band-pass filter, take
the avg. power and pass that through a A/D converter and use decoders to
turn on LEDs.  I was wondering if anyone out in .net-land had seen any 
good schematics (sp) and what the 16 best bands to use would be?

Any info would be appreciated.
