object BRF extends Serializable

A second order band reject (notch) filter UGen.

Examples
// modulated frequency
play {
  val in   = Saw.ar(200) * 0.5
  val freq = SinOsc.ar(XLine.ar(0.3, 100, 20)).madd(3600, 4000)
  BRF.ar(in, freq)
}
// mouse controlled frequency and Q
play {
  val in   = WhiteNoise.ar(0.5)
  val freq = MouseX.kr(200, 10000, 1)
  val q    = MouseY.kr(0.5, 10, 1) // bottom to top
  BRF.ar(in, freq, q.reciprocal)
}

    input signal to be filtered

    freq

    center frequency in Hertz

    rq

    reciprocal of Q. The Q (or quality) is conventionally defined as center-frequency / bandwidth, meaning that rq  = bandwidth / center-frequency. A higher Q or lower rq produces a steeper filter. Too high values for rq may blow the filter up!
