+ | __Psychoacoustic: | ||
+ | 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 yo a great extent. This prevents a boost by the correction filter which leads to a good correction at the listening place but also to an overboost at other listening positions.\\ | ||
\\ | \\ | ||
- | + | __Sliding Octave Analysis:u \\ | |
- | + | 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 accurately 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)\\ | |
- | + | 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 [[: | |
