Abstract:
The disclosure relates to an apparatus for generating a sound field on the basis of an input audio signal. The apparatus comprises a plurality of transducers, wherein each transducer is configured to be driven by a transducer driving signal q l  of the respective transducer; a plurality of filters configured to generate for each transducer the transducer driving signal q l  of the respective transducer; and a control unit configured to provide or receive a first transducer driving signal vector q 0  of dimension L such that the gradient of J(q;Ψ) with respect to q is zero in (q 0 ;Ψ 0 ), the control unit is further configured to provide a second transducer driving signal vector {tilde over (q)} of dimension L such that the gradient of the cost function J(q;Ψ) with respect to q is [approximately] zero in ({tilde over (q)};{tilde over (Ψ)}), the control unit is configured to provide the second transducer driving signal vector {tilde over (q)}.

Claim (Index 8):
The apparatus of  claim 4 , wherein the truncated Neumann series of order N is defined by the following equation:\n \u03a3 n=0 N \u0394\u03a8 D n E n , wherein \u0394\u03a8 D  denotes an adjustment of the dark zone weighting parameter \u03a8 D  and wherein the matrix E is defined by the following equation:\n E=\u2212A \u22121 Z D H Z D , \n wherein the matrix A is defined by the following equation:\n A=Z B H Z B +\u03a8 D Z D H Z D +\u03a8 G Z G H Z G +\u03b2I,  \n wherein Z B  denotes the transfer matrix for the bright zone, Z D  denotes the transfer matrix for the dark zone, and Z G  denotes the transfer matrix for the grey zone.
