Position-Dependant Volume/Running Time Correction

Position-Dependant Volume/Running Time Correction

The evaluators sit inside the vehicle. The digital signal processor makes a correction to the volume and the running time in order to compensate for the different lengths the sound has to travel to the individual speaker. The sound to the individual speakers is either increased or decreased.

The output via the individual speakers is delayed during the running time correction. That is, the signal is emitted sooner to the speakers that are further from the set position (for example, driver) than to the speakers that are closer to this position.
