1. Method for generating an acoustic multichannel audio signal and outputting same in a vehicle via an output apparatus comprising a plurality of output channels, the method comprising the steps of:
supplying an audio signal,
splitting the supplied audio signal into a plurality of perception-direction-dependent acoustic signal components each comprising individual directionally-dependent perceived audio signal information of the audio signal by means of a source separation apparatus, wherein
the supplied audio signal is split into at least one center signal component comprising directionally-dependent perceived audio signal information of the audio signal which would be perceived as center audio information, at least one left signal component comprising directionally-dependent perceived audio signal information of the audio signal perceived to the left of the at least one center signal component, and at least one right signal component comprising directionally-dependent perceived audio signal information of the audio signal perceived to the right of the at least one center signal component; wherein
before splitting, the audio signal is analyzed for individual signal components comprising individual directionally-dependent perceived audio signal information of the audio signal by one or more analyzing devices based on an output direction or position that would be perceived by a listener positioned in a defined position relative to an acoustic output apparatus that only comprises a left and a right output channel;
generating an acoustic audio signal by mixing each perception-direction-dependent acoustic signal component onto at least one output channel of the output apparatus, and
outputting the generated acoustic multichannel audio signal over the at least one output channel of the output apparatus.
