RLPF

A resonant low pass filter UGen.

Examples

// mouse controlled frequency and Q
play {
  val in   = WhiteNoise.ar(0.5)
  val freq = MouseX.kr(200, 10000, 1)
  val q    = MouseY.kr(1, 100, 1) // bottom to top
  val flt  = RLPF.ar(in, freq, q.reciprocal)
  flt / q.sqrt // compensate for energy loss
}

input signal to be filtered
freq
cutoff frequency in Hertz
rq
reciprocal of Q. The Q (or quality) is conventionally defined as cutoff-frequency / bandwidth, meaning that rq = bandwidth / cutoff-frequency. A higher Q or lower rq produces a steeper filter.
