lcd spectrum analyzer

Hello does anyone know about schematic and software for a pic based spectrum analyzer+LCD graphic display? I built an oscilloscope but I need also a small and portable unit to monitor audible frequencies (20Hz - 20Khz).

Thanks in advance

HI

IF YOU HAVE ALL READY BUILT AN OSCILOSCOPE JUST IMPLEMENT AN FFT ALGORITHIM THAT WOULD TURN YOUR SCOPE TO ASPECTRUM ANALYZER

you could modify the schematic and source for your PIC...
