Audi to introduce 3D sound system in its all-new Q7

Have you ever heard of a 3D sound system that gives your favorite music a spatial dimension, if not, then wait for the arrival of Audi's all-new Q7 SUV to experience it. A digital signal processor uses 11 channels with a total of 23 speakers to produce this type of first-of-its-kind 3D surround sound. Unlike the regular left and right channels, the system also gets a spatial height that makes your favourite music even clearer and more vivid.

The systems uses a complex algorithm that calculates the control signals for each speaker and recreates the environment in which a song was originally recorded in. Firstly, the system breaks down the data for the music source down into its spatial components, and then reassembles the sound portions, in a bid to correspond the original environment of the song.

Explaining this new sound system, Audi quoted, "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 innovative 3D sound system in the all-new Q7 is being developed the in collaboration with the Fraunhofer Institute for Integrated Circuits in Erlangen, Germany, and will be available with either the Bose or more expensive Bang Olufsen sound systems
