Description of position-dependent volume correction / time correction
The listeners inside the vehicle are not seated at equal distance from each loudspeaker.
In order to compensate for the different distances between each loudspeaker and the listeners, the digital signal processor corrects the volume and signal timing for each loudspeaker.
The volume correction function increases or reduces the volume of the audio signal output to a loudspeaker.
   
1 - Input signals to all loudspeakers
2 - Digital signal processor
3 - Signal strength for loudspeaker 1
4 - Signal strength for loudspeaker 2
5 - Signal strength for loudspeaker 3
6 - Signal strength for loudspeaker 4

The time correction function delays the output to a loudspeaker.
This means that a signal is output to the loudspeakers that are further away earlier than to those loudspeakers that are closer to the listener.
   
1 - Input signals to all loudspeakers
2 - Digital signal processor
3 - Delay for loudspeaker 1 (closest)
4 - Delay for loudspeaker 2
5 - Delay for loudspeaker 3
6 - Delay for loudspeaker 4 (furthest away)
