Fraunhofer IIS' four generations of audio codecs

The Audio and Media Technologies division of Fraunhofer IIS has been an authority in its field for more than 30 years, starting with the creation of mp3 and co-development of AAC and HE-AAC. Today, almost all consumer electronic devices, computers and mobile phones are equipped with Fraunhofer’s media technologies. The fourth generation of Fraunhofer audio codecs, along with the latest signal processing solutions, stands for impressive audio experiences and is tailored to specific fields of application respectively.

With the test plan for the Digital Cinema Initiative and the recognized software suite easyDCP, Fraunhofer IIS significantly pushed the digitization of cinema. The most recent technological achievements for moving pictures are light-field data processing tools and new low complexity codec standards for professional video production.
