audio spectrum analyzer kit

Velleman (used to) make a kit for this - you might be able to find schematics on the web. Look here:

Also tak e alook at this thread on bit-tech:

audio analyzer circuit

"Sure, a DSP can make the calculations and generate the pixel bitmap for an audio spectrum analyzer, but at what cost? Robert gets the same result from a single PIC processor with a design so good he walked away with a Design98 first prize."

May be even simpler with a current AVR flash based MCU...
