Abstract

An equalization filter coefficient determinator continuously or quasi-continuously fades between a plurality of different equalizer settings in dependence on one or more setting parameters, to obtain a current set of equalization filter target coefficients describing a current equalizer setting. A number of setting parameters is smaller than a number of equalization filter target coefficients of current set of equalization filter target coefficients. An equalization filter coefficient determinator linearly combines a plurality of equalization filter target coefficient set components in dependence on one or more setting parameters. An equalization filter coefficient determinator obtains the current set of equalization filter target coefficients in dependence on position information obtained using a two-dimensional or three-dimensional user input device. An apparatus includes a user interface, an equalization filter coefficient determinator and an equalizer. An equalization filter coefficient processor may provide sets of basis equalization filter target coefficients. A system is also described.
