Fraunhofer Symphoria®

Overview

Experience the boundless beauty of sound

Symphoria is a universal solution for rendering outstanding stereo and 3D surround sound in automotive environments. The intelligent post processing technology virtually opens up the sound image of your sound system, creating a new sense of dimensionality and spaciousness by increasing width, depth and even height of the sound image. In addition to delivering a more natural and realistic sound, automotive entertainment systems powered by Symphoria offer a highly improved perceived audio quality for every passenger in the car. This results in a broad and clearly defined front stage as well as a perfectly balanced surround sound field for each seat.

 

Symphoria embodies:

  • Stable high quality audio from any audio source (radio, mp3, CD etc.)
  • Support of any channel configuration of the input content (stereo, 5.1 surround, 3D audio)
  • Flexibility when designing a sound concept to meet manufacturers’ needs and branding requirements.
  • An extraordinary listening experience for any automotive sound system configuration, independent of loudspeaker type, position or number.
  • A reduction in car weight and therefore sound system costs: The application of intelligent audio signal processing allows for a cutback of sound system hardware.

 

Symphoria achieves results through the following steps:

During the first step the individual sound components within the audio signal are separated, with help of a semantic analysis process. Following the separation of the individual sound components, the tunable algorithm of Symphoria intelligently distributes the separated audio objects inside the car.

 

Collaborations

  • The Audi TT Coupé released in 2014 is the first production car equipped with the Fraunhofer technology Symphoria.
  • In December 2014, Audi announced that the new Q7 will deliver a three dimensional audio experience, which is powered by Fraunhofer Symphoria. The Q7 concept car equipped with Symphoria was already presented at CES 2013.
  • From the collaboration with Audi and Bang & Olufsen evolves the new Audi R8 Coupé (2015) featuring Fraunhofer Symphoria surround sound (2D).
  • A new sound dimension for medium-sized cars: Symphoria brings true 3D sound to the new Audi A4 and A4 Avant (2015).
  • Since 2016, passengers can enjoy best 3D sound with Symphoria in the new Mercedes-Benz E-class W 213 with Burmester sound system.

Cingo and Symphoria: Concert hall for on the move

Concert hall to go: Cingo and Symphoria enable a natural and immersive 3D audio experience. So you get to feel like you’re at a live concert – even when you’re actually listening on a mobile device or in the car. For the development and market launch of the two technologies their developers received the 2015 Fraunhofer prize.

The following video closer explains the working principles of both Fraunhofer technologies.
