Digital Spectrum analyzer ->led or lcd

Design Concepts
1

Hi there!

I was thinking about a spectrum analyzer to add that extra LOOK to the sid module, either lcd or baragraph, but I don’t really have a clue how to make/program.

I’ve seen pic based vocal harmonizers and pitch to midi converters, so there must be a way of converting Frequency dynamics to digital values… ???

Anyone out there seen a DIY pic based spectrum analyzer on the net?

Any help would be very handy for what could be a nice feature.

Thanks!

You’re probably interested in Robert Lacoste’s “PIC’Spectrum” analyzer from Circuit Cellar, September 1998, Issue 98: http://www.circuitcellar.com/library/print/0998/Lacoste98/  That should at least get you started ih the right direction to making an LED/LCD-based one

Alternately, for slightly less visual pizazz, an LED VU meter might do the trick.  I’ve been considering reusing an old meter I built years ago for that.
