Digital, real time, Audio Frequency LED Spectrum Analyzer

https://www.circuitlib.com/index.php/lessons/116-digital-real-time-audio-frequency-led-spectrum-analyzer

The Digital, real-time Audio Spectrum analyzer circuit for audio devices can be connected to any audio device. It accepts an analog audio signal as input. It digitizes and processes this audio signal using a DSP. It computes the distribution of the audio signal energy to 20 specific frequency bands and displays it on a 20x20 LED display.
