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 custom bluetooth speaker project conceived from an FFT mini-project. This MCU version serves as a test bed for the [FPGA version](https://github.com/Gunmetal-61/FFT ...

Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just that, relying on some staple maker ...

We live in a world in which nearly any kind of gadget or tool you can imagine is just a few clicks away. In many respects, this has helped fuel the maker culture over the last decade or so; now that ...

Abstract: This paper discusses about an advanced smart audio visualizer with equalizer, by assembling Arduino, DFPlayer mini, Metal Oxide Semiconductor Field Effect Transistor (MOSFET), an arrangement ...

A $10 Ikea table was transformed into a one-of-a-kind music visualizer, complete with LED lights, electronic components and a microphone. Author Charlie Turner wrote on Make: Magazine a step-by-step ...
