ParagraphicEQ is a simple four-band paragraphic equalizer VST plugin for windows and linux. It uses the biquad design from https://www.musicdsp.org/en/latest/Filters/197-rbj-audio-eq-cookbook.html.
Using this plugin is very simple. There are a total of eight knobs - four knobs are used to set frequencies, and the other four control the the gain in dB. The Q Factor is proportional to the amount of gain. Basically, the Q Factor is equal to the amount of gain times a constant value which is universal across all bands. This constant is a value between 0 and 1, and it is decided by the user with the slider labeled "Q Proportion".
