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.

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)
