i have to draw a GUI in xcode cocoa app, for a parametric equalizer which i have gains, freq, and q paramiters. My idea is to use NSBezierPath but i have no ideas how to get the points to build it. Some suggestions ? Thanks a lot

You can use NSBezierPath moveToPoint, lineToPoint and curveToPoint functions. Please check this link http://www.knowstack.com/nsbezierpath-curves-and-graphs/

  • i know ho to use NSBezierPath , the question is : how to calculate the points for a given parametric equalizer ? – mattiad Feb 04 '15 at 21:13
  • Then, you have to explain what this "parametric equalizer" is. – fang Feb 05 '15 at 01:23
  • in this link there is an explanation http://en.wikipedia.org/wiki/Equalization_(audio)#Parametric_equalizer end this is a graphic example http://bedroomproducersblog.com/wp-content/uploads/2012/10/eq4-cis.jpg – mattiad Feb 05 '15 at 09:31
  • It is doubtful that anyone who is unfamiliar with a parametric equalizer would have an answer to this question. – jessecurry Dec 11 '20 at 15:27
