Claim One:
1. A method of adjusting an equalizer setting for an audio signal equalizer to a user's preference, the method being performed by an audio processing unit that comprises an equalizing unit and an input unit, the method comprising the steps of: selecting a first and a second equalizer setting from a current population of equalizer settings for undergoing a binary comparing decision; presenting the two equalizer settings to a user by consecutively replaying an audio signal filtered by an equalizing unit according to the first or to the second equalizer setting respectively; acquiring the user's binary comparing decision between the first and the second equalizer setting according to his preferences via an input unit; performing further binary comparing decisions with pairs of two further equalizer setting from the current population of equalizer settings until all members of the current population of equalizer settings have been part of a binary comparing decision; adapting a score for each presented equalizer settings based on the user's binary comparing decisions results, wherein equalizer settings preferred by the user receive higher scores than equalizer settings not preferred by the user; iterating the population according to the user's preferences by removing equalizer settings from the population that received a low score; generating new members of the population based on the binary comparing decisions results and appending them to the remaining current population, whereby a new population is obtained; iteratively re-performing the binary comparing procedure for the complete new population; and performing a weighted averaging in the frequency domain between the equalizer settings of the new population that received a high score, the weighting being based on the scores; wherein the result of the averaging represents the result of the equalizer adjustment method.
