-The psychoacoustic smoothing (green) follows the given pulse response (red) pretty well like an envelope curve. A resulting filter can lower the peaks accordingly to achieve the desired frequency response at the listening position. The dips in the frequency response are ignored for big amount. This prevents a boost by the correction filter which kleads to a good correction at the listening place but also to an overboost at other listening positions.\\+The psychoacoustic smoothing (green) follows the given pulse response (red) pretty well like an envelope curve.

-The sliding octave analysis (brown) follows the peaks and dips depending on the octave parameter setting. Based on the result it is possible to create a correction filter which linearizes the frequency response more accurate but with the disadvantage of being more position dependent. If there is only a single listening position the octave analysis function can be a good choice (ignoring the risk of bass overboost at other room positions)\\ +The sliding octave analysis (brown) follows the peaks and dips depending on the octave parameter setting.

-There is also the possibility to combine both smoothing methods. So a psychoacoustically smoothed curve for midrange and trable can be combined with a curve, smoothed by a sliding octave analysis for the lower frequency range. See the Acourate function [[:en:wiki:funktionen:fd-functions:amplitude_splitnjoin|Amplitude SplitNJoin]]\\+There is also the possibility to combine both smoothing methods.
