AmpCompA

A UGen that produces a psychoacoustic amplitude compensation factor for a given frequency. It uses the A-weighting curve that is based on the Fletcher-Munson curve for rather low volume sounds (40 phon).

Only the freq parameter can be modulated, the other parameters are read at initialization time only.

Examples

// activate with mouse button
play {
  val freq = MouseX.kr(300, 15000, 1)
  val mod  = freq * SinOsc.ar(MouseY.kr(3, 200, 1)).madd(0.5, 1)
  val corr = AmpCompA.ar(mod, 300) * 2
  val amp  = Select.ar(MouseButton.kr(lag = 0), Seq(DC.ar(1), corr))
  SinOsc.ar(mod) * 0.1 * amp
}

freq
the frequency in Hertz for which to determine the compensation factor
root
the root frequency in Hertz, relative to which the curve is calculated. This is usually lowest expected frequency.
minAmp
amplitude at the minimum point of the curve. This is the factor output when freq is approx. 2512 Hz.
rootAmp
amplitude at the root frequency of the curve. This is the factor output when freq == root .
