Method for outputting an audio signal into an interior via an output device comprising a left and a right output channel

Method for outputting an audio signal into an interior forming part of a passenger compartment of a motor vehicle via an acoustic output device comprising a left and a right acoustic output channel, comprising the steps:

• supplying an audio signal to be split into a plurality of acoustic audio signal components, each corresponding to a listener's aural direction of perception,
• splitting, via a splitting device comprising a source separation device, of the supplied audio signal into a plurality of acoustic audio signal components each corresponding to a listener's aural direction of perception,
• mixing, via the mixing device, of each of the plurality of acoustic audio signal components dependent on the listener's aural direction of perception to a right or left output channel of an acoustic output device comprising a right and a left acoustic output channel into a plurality of mixed acoustic audio signal components comprising a center audio signal component whereby a virtual center output channel for the center audio signal is generated, and
• outputting each of the plurality of mixed acoustic audio signal components, via the right and the left acoustic output channel of the acoustic output device, whereby the center audio signal component is output via the right and/or the left acoustic output channel of the acoustic output device;
• wherein
• the splitting device and the mixing device are separate devices, and
• before splitting, the audio signal is analyzed via analyzing algorithms associated with the splitting device to determine individual audio signal components, which in an output of the audio signal via an output device comprising a left and a right output channel would correspond to an output direction or position perceived by a listener in a defined listening position relative to such an output device comprising a left and a right output channel.
