I'm assuming you're talking about the analyzer? The spectrum analyzer chip is
MSGEQ7, which comes in DIP-8 and SOIC-8. You can find it on sparkfun in the DIP
package, but the SOIC version is harder to find. I'll dig up the place where
you can get it if you want.

As for why 7 channels, I found a little IC that breaks down audio into DC

I'm using the IC. I will definitely investigate the fft when I can.

It would be cool to make one with more channels for analyzing the
quality of your amateur radio transmissions.. Something to think about
for another day. :) My Swan 500c puts spurious emissions all over the
place. I probably don't want to know what they look like. :S

Ascending and descending orange glow tubes, why wouldn't it sell! I'd
probably tinker with one...;-) Why only 7 channels? May I ask what
frequency ranges you decided to sample?

Pretty neat. As an audiophile toy, I suspect that it would sell well.
Something to put on top of that all-tube amplifier.

Hello everyone,
I am thinking of selling a IN-13 spectrum analyzer, either fully assembled
or in kit form. I've just ordered the preliminary boards to get the final
prototype together, but it would be 7 bands with a 3.5mm jack input. 12v
input from wall power, and possibly a mini USB port. The
