LED Bar Audio Spectrum Analyzer

Audio spectrum analyzers have always been cool either in Winamp on your computer, or in a sound system that features it. Now you have the option of building it and including it into your soundsystem. In fact i think it would look very professional if you place it inside a nice case.

The real-time system computes the distribution of the audio signal energy to 20 specific frequency bands and displays it on a 20 × 20 LED display. The PIC30F6012A was choose to control this circuit  because of its numerous functions needed in this project.
