   6 description::
   7 The B equalization suite is based on the Second Order Section (link::Classes/SOS::) biquad UGen.

   9 note::
  10 Biquad coefficient calculations imply certain amount of CPU overhead. These plugin UGens contain optimizations such that the coefficients get updated only when there has been a change to one of the filter's parameters. This can cause spikes in CPU performance and should be considered when using several of these units.
