Using time correction
In any car, it is nearly impossible to set in a spot
that is the same distance from each speaker.
Using this function, it is possible to delay the
sound from speakers closer to the listener. This
makes them sound like they are the same
distance as the speakers located farther away.
Sit in the listening position (driver's seat, etc.)
and measure the distance (in meters) between
your head and the various speakers.
Calculate the difference between the distance
to the farthest speaker and the other speakers.
L= (distance to farthest speaker) – (distance to
other speakers)
Divide the distances calculated for the speakers
by the speed of sound (343 m/s at 20°C).
These values are the time correction values for
the different speakers.
