Fraunhofer Institute for Integrated Circuits
A modern car provides access to an array of multimedia entertainment. Fraunhofer IIS offers a number of technologies that enable automobile manufacturers to realise impressive audio-visual systems for their increasingly demanding customers. Widely available audio and video codecs are just as much a part of this as forward-looking multimedia technologies such as lossless storage of music or the processing and reproduction of high quality surround sound at low bit rates.
Fraunhofer IIS provides advice on future technologies with relevance to the car industry and continues to develop solutions which are optimized specifically for use in automobiles. A recent example is SX Pro, which was conceived by Fraunhofer IIS to enable effective processing of stereo music for car speaker systems

Audio codecs:
- AAC-LC: Most common AAC profile, used e.g. by iPod
- HE-AAC, HE-AAC v2: Improved quality below 64 kbit/s
- HD-AAC: Lossless audio coding compatible to AAC
- mp3: The standard for compressed music
- mp3 Surround: 5.1 sound at mp3 stereo bitrates
- MPEG Surround: 5.1 sound at stereo bitrates
Video Codecs:
Surround Audio Technologies:
- mp3D: Improved playback of stereo and 5.1 over headphones
- mp3 Surround: 5.1 sound at mp3 stereo bitrates
- MPEG Surround: 5.1 sound at stereo bitrates
- SX Pro: Creates surround content from any stereo content
- HE-AAC, HE-AAC v2: For discrete 5.1 sound at low bit-rates
