FIELD: general-purpose electronic circuits.
SUBSTANCE: invention relates to determination of equalisation filter coefficients. Number of setting parameters is smaller than a number of equalisation filter target coefficients of current set of equalisation filter target coefficients. Equalisation filter coefficient determinator is configured to linearly combine a plurality of equalisation filter target coefficient set components in dependence on one or more setting parameters, to obtain the current set of equalisation filter target coefficients depending on two-dimensional position information or three-dimensional position information obtained using a two-dimensional or three-dimensional user input device.
EFFECT: technical result of the invention is the ability to perform continuous or quasi-continuous damping between a variety of different settings of a frequency equaliser depending on one or more setting parameters.
