See Sound with Audiolux One

This plug-and-play device was designed by Deaf & Hearing engineers to transform sound into light with LED pixels.

Audiolux One is a plug-and-play device that transforms sound to light. It represents a revolution for the Deaf in particular, as it makes “seeing sound” possible. Designed by a Deaf musician, the technology has drastically altered the way that he, and others like him see and experience music. Audiolux One is now being used to make arts & cultural events inclusive to the Dead & Hard-of-Hearing.

In true Hackaday fashion, you have total freedom to customize the audio analysis, LED layouts and visualization algorithms or modify the functionality of the hardware knobs and footswitch since Audiolux Devices software is fully open-source and Arduino-compatible. For those unfamiliar with programming, you can use the default pre-loaded visualizations or upload new presets and tweak existing visualizations provided in our github.

With Audiolux One, we are uniting the Deaf & hearing communities with this unique piece of equipment, and we invite you to be there with

What is Audiolux One? 

Audiolux One is a plug-and-play stompbox that analyzes audio in real-time & generates music visualizations for smart LED pixels. Transform sound into light!

    Build your own Audiolux One with open-source hardware & software.

    Build Your Own Audiolux One Clone

    Open source Lighting system for Deaf & Hard-of-Hearing to see music & alerts using Arduino & digital LEDs.



    1. Step 1: Connect Sparkfun Spectrum Audio Shield to the Arduino (it will fit exactly onto an Arduino Uno).
    2. Step 2: To quickly get up and running follow the steps in the Adafruit Neopixel Uberguide:
    3. Connect the +5V input on the LED strip to the + (positive) terminal on the Arduino/Spectrum Shield, DIN to digital pin 5 on the Arduino/Spectrum Shield, and – (minus or GND) on the strip must connect to a GND pin on the Arduino/Spectrum Shield (there are usually several — any will do).
    4. Step 3: Install Arduino IDE & Arduino NeoPixel Library (again reference Adafruit Neopixel Uberguide for more detailed instructions).
    5. Step 4: Download our software sketch '/Cymatic-Lighting' from Github and unzip the contents into your Arduino Sketches folder.
    6. Step 5: Upload sketch from Arduino software IDE to the Arduino hardware (make sure USB cable is connected to computer if not already!).
    7. Step 6: Plug in a standard 3.5mm audio cable into either audio jack on the Spectrum Audio Shield and the other end into a sound-source (MP3 Player, Phone, “Handimic” Microphone with line level output etc).
    8. Step 7: Play music or make sound and enjoy the visualization on the LED strip.
