I want to show (graphically) the Gain/Attenuation vs frequency of a parametric equalizer.
This is my circuit:
The same schematicas as a screenshot:
I want to show the effect of VR1 thru VR7 in the same way as it's shown in the Winamp:
I have tried to decipher this page: https://www.andyc.diy-audio-engineering.org/parametric-eq-parameters-1.html
I don't know how to interpret the formulas to derive the Gain/Attenuation, given the frequency, Q and center frequency of each equalizer band. Can anybody please explain in simple terms?
