object LFDNoise3 extends Serializable

A dynamic ramp noise UGen. It is similar to LFNoise2 , with three differences: It uses cubic instead of quadratic interpolation for the random values between -1 and +1 at a rate given by the freq argument. There is no time quantization, and it there is fast recovery from low freq values.

In contrast, LFNoise0 , LFNoise1 , and LFNoise2 quantize to the nearest integer division of the sample rate, and they poll the freq argument only when scheduled, and thus seem to hang when the frequencies get very low.

Examples
// compare dynamic and non-dynamic
play {
  val r    = MouseX.kr(0.1, 1000, 1)
  val a    = LFNoise2 .ar(r)
  val b    = LFDNoise3.ar(r)
  val freq = Select.ar(MouseButton.kr(lag = 0), Seq(a, b))
  SinOsc.ar(freq.madd(200, 500)) * 0.2
}
