Twelve speakers and a Bang & Olufsen Sound System for the Audi TT

The new Audi TT also demonstrates its innovation in other areas, as it incorporates the Bang & Olufsen Sound System, which uses the innovative Symphoria technology for a fascinating audio experience, working as follows.

A processor analyses the noise detected inside the cabin via a microphone in order to optimise the sound in the interior. When combined with MMI navigation plus, the sound is also played back in 5.1 surround format.

With 680 watts of power, the amplifier drives twelve speakers, including two centre speakers and two encapsulated subwoofers in the doors. The sound system is accentuated visually by an aluminium strip running along the edge of the woofer speakers. A white light thus emerges from a narrow LED light guide.

In collaboration with specialists from the Fraunhofer Institute for Integrated Circuits in Erlangen, Audi has developed the Symphoria software for the post-processing and rendering of audio signals. In the first phase, the program separates the individual sound components within the audio signal. It then distributes these audio components throughout the interior of the car.

The soundstage becomes wider and deeper, conveying a completely new spatial impression. Every passenger enjoys maximum quality and an absolutely perfect audio experience.

Audi has been a benchmark in car audio systems for eight years. In 2005, the Bang & Olufsen Advanced Sound System debuted in the Audi A8, offering outstanding audio quality. In 2012, premium sound was introduced in the compact car segment with the arrival of the third generation Audi A3.

With Symphoria, the brand of the four rings is taking a major step towards 3D sound, a technology that Audi first presented at the Consumer Electronics Show (CES) in Las Vegas in early 2013. 3D sound also allows the listener to experience spatial height as a third dimension, which will undoubtedly be the next step on the path to the audio experience of the future.
