<p>It is provided a method for configuring an electronic device comprising an equalizer suited for processing a numeric audio signal according to an objective equalization. The equalizer has a transfer function that implements a set of band-pass filters having a constant band-pass and a configurable weight in the transfer function The method comprises providing (S10) a set of objective gains representing the objective equalization, each objective gain corresponding to a respective frequency. The method also comprises determining (S20) values of the weights of the band-pass filters that minimize an error evaluated by comparing the set of objective gains to the transfer function, wherein the set of band-pass filters comprises at least one pair of band-pass filters having a common central frequency and distinct band-passes. The method also comprises setting (S30) the weights of the band-pass filters to the determined values. Such a method improves the equalization of a numeric audio signal.</p> |
