This project shows my graphic equalizer for analysis  and visualization of audio signals with the new embedded KIT of Altera cyclone III.

Base Hardware Unit
Altera Cyclone III Neek embedded Kit

Altera Neek embedded Kit used for audio visualisation

The Altera Cyclone III from Terasic is used to implement a graphical visualization of the analized audio.
