object MidEQ extends Serializable

A single band parametric equalizer UGen. It attenuates or boosts a frequency band.

Examples
// mouse controlled frequency and boost
play {
  val in   = WhiteNoise.ar(0.25)
  val freq = MouseX.kr(200, 10000, 1)
  val gain = MouseY.kr(-12, 12) // bottom to top
  MidEQ.ar(in, freq, rq = 0.5, gain = gain)
}

  4. def ar(in: GE, freq: GE = 440.0f, rq: GE = 1.0f, gain: GE = 0.0f): MidEQ

    in

    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!

    gain

    The amount of boost (when positive) or attenuation (when negative) applied to the frequency band, in decibels.
