Find the peak nearest to the Freq frequency and return the frequenyc of the newly found peak.

Pascal
function PeakApproximate(Freq: Double; var spcEstimate: TCplx): Double; overload;
Description

This overload returns also spcEstimate, which is the spectral line of the complex spectrum at approximated Freq. Only the numeric peak interpolation will return something else that the nearest peak for spcEstimate. This spcEstimate can then be passed on to the AmpltEst, which accepts also the complex parameter.
