object Median extends Serializable

A filter UGen that calculates the median of a running window over its input signal. This non-linear filter can be used to reduce impulse noise from a signal.

Examples
// engage with mouse button
play {
  val in  = Saw.ar(500) * 0.1 + Dust2.ar(100) * 0.9 // signal plus noise
  val flt = Median.ar(in, 3)
  LinXFade2.ar(in, flt, MouseButton.kr(-1, 1))
}
// long filter distorts by chopping off peaks in input
play { Median.ar(SinOsc.ar(1000) * 0.2, 31) }
Note

The argument order is different from its sclang counterpart.
