This project implements a hardware-accelerated spectrum visualizer on an FPGA platform. Audio signals are processed in real-time using Fast Fourier Transform (FFT) to analyze frequency components and ...

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 ...

You may be wondering how a sound visualizer could be the “next version” of anything. What’s interesting about GRID is that it’s a networked multitouch sound ...

Visualizers used to be very much in vogue, something you’d gasp in at amazement when you’d fire up Winamp or Windows Media Player. They’re largely absent from our modern lives, but [Arnov Sharma] is ...

Waveform Visualizer is a wall-mounted LED display that turns background noise into a clean, oscilloscope-style waveform. Built around a Raspberry Pi Pico 2, it samples a microphone module and renders ...
