摘要：
An equalization filter coefficient determinator for determining a current set of equalization filter target coefficients for use by an equalizer is configured to continuously or quasi-continuously fade between a plurality of different equalizer settings in dependence on one or more setting parameters, to obtain the 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 is configured to linearly combine a plurality of equalization filter target coefficient set components in dependence on one or more setting parameters, to obtain the current set of equalization filter target coefficients.
An equalization filter coefficient determinator is configured to obtain the current set of equalization filter target coefficients in dependence on a two-dimensional position information or a three-dimensional position information obtained using a two-dimensional or three-dimensional user input device.
An apparatus comprises 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 may use an equalization filter coefficient processor and an equalization filter coefficient determinator.
