While [Vinod] says he’s not an expert in this sort of thing, we really like his audio spectrum analyzer build from a simple microcontroller and LCD display. It is a well-studied fact that every audio ...
The AVR project utilizes a small graphics LCD to display the monitored spectrum and waveform of audio signal. The full graphics type LCD module used is the SG12232C with a resolution of 122(H) x 32 (V ...
The circuit has been designed to create a spectrum analyzer that will provide an analysis of a sound to determine at various frequencies, the volume of sounds that make up the overall sound spectrum.
