Designed to set a new benchmark for "in-car listening pleasure," the 3D sound systems use a complex algorithm that can recreate the environment that a song was sung in.

Audi has released new details about their 3D sound systems in the 2015 Q7.

Designed to set a new benchmark for "in-car listening pleasure," the systems use a complex algorithm that can recreate the environment that a song was sung in.

As Audi explains, "When an artist is singing from a stage, the floor, ceiling and walls of the concert hall reflect the sound with different time lapses. It bounces off the floor in just a few milliseconds, while it is only reflected by a wall 40 meters (131.2 ft) away after more than 200 milliseconds. Using these different sonic reflections, the algorithm is able to calculate a mathematical model of any recording room."

The system recreates this experience by using the calculations to play the sound at slightly different times from each speaker. The Bose and Bang & Olufsen audio systems have four speakers that are mounted relatively high to recreate the spatial height of the original recording.
