Illustrational displays and lights, pulsing to the rhythm of music are quite

popular visual elements today. My dissertation focuses on creating a design for such an

audio-visual tool, and – based on this design – creating the device itself. The goal was

to create real-time visual effects based on the played audio.

The device had to be a separate, independent visualizer tool, which can be

connected to various audio players.

The project was based on a microcontroller, which operates a programmable

LED panel. The controller processes the input audio signal with real time signalanalysis,

and based on this creates a visualisation.

In my dissertation I go through the various steps of the design creation, then I

present a detailed description of the assembly of the device itself, highlighting the

various complications, I had to overcome.

During the project, I managed to reach every goal which I determined at the

beginning. I successfully designed and created a device to meet my requirements, which

were also described at the beginning of the project. I also managed to learn much about

various new technologies, and I could widen my knowledge this way.
