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
