AB  - A frequency domain, multipoint equalization algorithm can be used to improve sound quality in a variety of spaces ranging from automobiles to home living rooms. The equalizer is designed in the frequency domain. From a set of smoothed impulse responses, suitable frequency prototypes are extracted. Inverse filters are then obtained by frequency deconvolution with regularization or LPC modeling. Compared to single-point equalization, the proposed algorithm proves to be superior in terms of spectral deviation and robustness. Various computational methods have been explored. Then the robustness of multipoint equalization is also evaluated for positions that differ from those used for the equalizer estimation.
