Q Gain compensation

    Nov 14 2013 | 2:20 pm
    At first sorry for my Eng.
    I'm working on an additively subtractive synth based on noise pocessing. At this moment i have a problem with gain compensation by increasing Q.
    To tell in simple words: when i'm raising Q very high, the volume drops very low.
    To make a calculation is not very hard for me, but i really can't figure it out what formula should i use as base.
    Could anybody please help me?
    If needed i'll post everything you want, from my patch.

      you didnt say what "Q" refers to.
      i assume we are talking about a biquad filter.
      if you have biquad lowpasses in serial you would simply add the Q values: 2 filters with a Q of 0.4 each will sound similar to one at 0.8, and the Q values should be limited at 0.4999 each.

      Thanks for response =)
      But my problem also is that i'm using Q values from 0.2 to 500.
      A little bit of my insane thoughts.
      At this moment i have 16 biquad BP filters. I understand that equal gain of filters i will get by dividing incoming signal on sum of all gain parameters for every filter. And asi understand his is not the main priority for me now.
      Also here is my patch.
