In this topic, we will focus on the design details of a Digital, real-time Audio LED Spectrum analyzer. The aim focuses on building a device to display the distribution of an audio signal energy to 20 specific frequency bands, using DSP technology. We will use fast Fourier transform (FFT) in order to analyze any audio signal in real time. The obtained Fourier transform will result in a bank of 20 parallel frequency filters. The output of the filters will be displayed on a simple 20 x 20 LED display. The unit will be designed to support up to four different display-modes.
