In one of our earlier instructables, we built an Arduino based Audio Spectrum Visualizer using our bi-color LED Matrix modules for the display. You may check it out at https://www.instructables.com/id/Arduino-based-Bi-color-LED-Matrix-Audio-Spectrum-V/
A few months ago, we designed jolliCube, an 8x8x8 LED cube. We are very encouraged to know quite a few entry level electronics hobbyists has bit the bullet and managed to successfully complete their 8x8x8 jolliCube instead of working on a smaller LED Cube as their first cube. You may find our LED cube project at https://www.instructables.com/id/JolliCube-an-8x8x8-LED-Cube-SPI/
Recently, we stumbled upon a 3D Audio Spectrum on Analyzer on YouTube. We were mesmerized by it.

In this instructable, we will use the electronic circuit we put together from our Arduino based Audio Spectrum Visualizer project to drive our jolliCube re-arranged with the 2 sets of 3D 8x8x4 LED Matrix displays placed side by side to form a 3D Stereo Audio Spectrum Visualizer Display.
To build this project, basic electronics knowledge with electronics component soldering skill and some knowledge on using the Arduino are required.
You may view the following YouTube video to see what we will be building.
To build the 2 sets of 3D LED Matrix displays is to practically build the entire jolliCube up with only some steps omitted.
Follow main Steps 1 to 6 in our instructable for JolliCube - an 8x8x8 LED Cube (SPI) to build the 2 sets of 3D LED Matrix displays but omit steps 5, 7 and 15 at Step 5: Assembly Part 2 - Complete the LED Cube with control circuit if you do not intend to use them to create an 8x8x8 LED cube.
