When speaking about spectrum we know that there is a Fourier transform involved. Probably this is the trickiest part of the business. Vinod felt like he needed to refresh his Fourier transform knowledge and made a small spectrum analyzer that displays frequencies from 0 to 10kHz. His choice was Atmega32 microcontroller running at 16MHz, text LCD and audio input circuit that …

· A long time ago I made a simple spectrum analyzer using an atmega, a 16x2 display, and some op-amp to center audio at 2.5v, to feed into the atmega adc. I used ElmChan FFT lib, and custom chars going from 0 to 7 bars so it had 15 "states" on each column for a bit more resolution, it was fast-ish(around 14Hz), but every now and then it would ...
