This project creates a real-time audio spectrum visualizer using a microcontroller (Arduino/ESP32), a microphone, and an LED matrix. It analyzes audio input, performs a Fast Fourier Transform (FFT), ...
A real-time stereo audio spectrum analyzer that displays frequency content on a 16×16 LED matrix using dual MSGEQ7 ICs and Arduino. The visualizer processes stereo audio through two MSGEQ7 graphic ...
