This is a real time LED Audio Spectrum Analyzer. You can embed this unit in an audio system or use it as a stand-alone unit. The LED Spectrum Analyzer can display a real-time bar-graph spectrogram on a 20 x 20 LED display in four different ways. It produces very nice visual effects and simultaneously provides an effective observable way to inspect audio performance during …

An audio spectrum analyzer is an audio spectrum analyzer . Many modern audio devices, such as amplifiers, audio-equalizers, audio mixers, and audio players . on LCD, CRT or LED display. The spectrogram does not contain any audio effects during playback, recording or during any tonal adjustment (bass, treble, mid frequencies adjustment or adaptive equalization).

Introduction. This project implements a real-time audio spectrum analyser using a PIC18F4550 8-bit microcontroller. The spectrum frequency analysis is performed by a highly optimised 16-bit Fast Fourier Transformation (FFT) routine coded entirely in C. The output from the FFT is displayed using a 128×64 graphical LCD to allow a real-time view of an audio signal.
