Abstract:
An apparatus for generating a plurality of loudspeaker signals from two or more audio source signals is provided. Each of the two or more audio source signals shall be reproduced in one or more of two or more sound zones, and at least one of the two or more audio source signals shall not be reproduced in at least one of the two more sound zones. An audio preprocessor is configured to modify each initial audio signal of the two or more initial audio signals depending on a signal power or a loudness of another initial audio signal of the two or more initial audio signals. A filter is configured to generate the plurality of loudspeaker signals depending on in which of the two or more sound zones the two or more audio source signals shall be reproduced and depending on in which of the two or more sound zones the two or more audio source signals shall not be reproduced.

Claim (Index 12):
The apparatus according to  claim 11 ,\n wherein the filter is configured to generate the plurality of loudspeaker signals depending on in which of the two or more sound zones the two or more audio source signals shall be reproduced and depending on in which of the two or more sound zones the two or more audio source signals shall not be reproduced by determining the filter coefficients of the FIR filter according to the formula\n g q =( H H W q H W q H ) \u22121 H H W q H W q d q  \n wherein g q  is a vector comprising the filter coefficients of the FIR filter according to\n g q =( g q,1 (0), . . . , g q,1 ( L G \u22121), g q,2 (0), . . . , g q,2 ( L G \u22121), g q,N L (0), . . . , g q,N L ( L G \u22121)) T  \n wherein H is a convolution matrix depending on a room impulse response, wherein W is a weighting matrix, wherein d q  indicates desired impulse responses, wherein g q,i  indicates one of the filter coefficients with 1<r<N L , wherein N L  indicates a number of loudspeakers, and wherein L G  indicates a length of the FIR filter.
