Plottin Filter for Equalizer-Visualisation

hi there,


first let me say "sorry" for my bad english, but i will do my best. ok i want to know, how i could draw lines to visualize an equalizer. i know the path-class and draw functions etc. and i am able to draw a line for one filter (like lowpass). for that i use lineTo and cubeTo from the path-class, but how could i create a resulting path from all single passes. is it possible do create a median path or what should i do? the fabfilter pro-q is a really good example. here is a screetshot of it.


Thanks a lot and greetz from germany

I don’t think this is normally done on the path side. Simply create the response of each filter section and calculate the overall response from these.


This may be a good starting point...
