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 ...

If you have a Raspberry Pi connected to an LED matrix, you might think about creating a simple oscilloscope. Of course, the Pi isn’t really well-suited for that and neither is an LED matrix, so ...

A spectrum visualizer is always a fun project, but we really liked [Yannick99]’s take on it since it uses seven IN-13 Nixie tubes for the display. The tubes, of course, need high voltage so part of ...
