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 3):
The apparatus according to  claim 1 ,\n wherein the audio preprocessor is configured to modify each initial audio signal of the two or more initial audio signals depending on the signal power or the loudness of another initial audio signal of the two or more initial audio signals by determining a gain for said initial audio signal and by applying the gain on said initial audio signal, wherein the audio preprocessor is configured to determine the gain depending on the ratio between the first value and the second value, said ratio being a ratio between the signal power of said another initial audio signal of the two or more initial audio signals and the signal power of said initial audio signal as the second value, or said ratio being a ratio between the loudness of said another initial audio signal of the two or more initial audio signals and the loudness of said initial audio signal as the second value.
