BRF 2nd order Butterworth band reject filter

Inherits from: Object : AbstractFunction : UGen : Filter : BPF

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

BRF.kr(in, freq, rq, mul, add)

A second order low pass filter.

in - input signal to be processed

freq - centre frequency in Hertz.

rq - the reciprocal of Q. bandwidth / cutoffFreq.
