object SOS extends ProductReader[SOS] with Serializable

A second order filter section (biquad) UGen. Filter coefficients are given directly rather than calculated for you. The formula is equivalent to:

out(i) = a0 * in(i) + a1 * in(i-1) + a2 * in(i-2) + b1 * out(i-1) + b2 * out(i-2)
Examples
// same as TwoPole
play {
  val theta = MouseX.kr(0.2*math.Pi, 0.9*math.Pi)
  val rho   = MouseY.kr(0.6, 0.98)
  val b1    = 2.0 * rho * theta.cos
  val b2    = -(rho.squared)
  SOS.ar(WhiteNoise.ar(Seq(0.05, 0.05)), 1.0, 0.0, 0.0, b1, b2)
}
// used as control signal
play {
  val theta = MouseX.kr(0.2*math.Pi, math.Pi)
  val rho   = MouseY.kr(0.6, 0.99)
  val b1    = 2.0 * rho * theta.cos
  val b2    = -(rho.squared)
  val vib   = SOS.kr(LFSaw.kr(3.16), 1.0, 0.0, 0.0, b1, b2)
  SinOsc.ar(vib * 200 + 600) * 0.2
}
