This project attempts to use a field-programmable gate array (FPGA) as a digital graphic equalizer. It analyzes an input audio signal and displays the frequency spectrum levels in real-time. Users would be able to attenuate the levels (represented on the vertical axis of the display) of individual frequencies (laid-out horizontally) without traditional knobs or sliders, but instead by hovering their finger at the desired height on the display for any of the frequencies displayed.
