BHiPass 12db/oct rolloff - 2nd order resonant  Hi Pass Filter.

Inherits from: Object : AbstractFunction : UGen : Filter : BEQSuite

BHiPass.ar(in, freq, rq, mul, add)

in - input signal to be processed

freq - cutoff frequency.

rq - the reciprocal of Q.  bandwidth / cutoffFreq. 

*sc(dummy, freq, rq)

calculate filter coefficients.

The B equalization suite is based on the Second Order Section (SOS) biquad UGen.

note: 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.
