final case class AmpCompA(rate: Rate, freq: GE = 1000.0f, root: GE = 0.0f, minAmp: GE = 0.32f, rootAmp: GE = 1.0f) extends SingleOut with Product with Serializable
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.
- 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. (init-time only)
- minAmp
amplitude at the minimum point of the curve. This is the factor output when
freq
is approx. 2512 Hz. (init-time only)- rootAmp
amplitude at the root frequency of the curve. This is the factor output when
freq == root
. (init-time only)
