Zusammenfassung: | An apparatus for generating a plurality of loudspeaker signals from two or more audio source signals, wherein each of the two or more audio source signals shall be reproduced in one or more of two or more sound zones, and wherein 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, wherein the apparatus comprises: an audio preprocessor configured to modify each of two or more initial audio signals to obtain two or more preprocessed audio signals, and a filter configured to generate the plurality of loudspeaker signals depending on the two or more preprocessed audio signals, wherein the audio preprocessor is configured to use the two or more audio source signals as the two or more initial audio signals, or wherein the audio preprocessor is configured to generate for each audio source signal of the two or more audio source signals an initial audio signal of the two more initial audio signals by modifying said audio source signal, wherein the 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, and 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. 18602395_1 (GHMatters) P109857.AU.2 |
