Karlheinz Brandenburg (born 20 June 1954 in Erlangen) is a German audio engineer who has contributed to the audio compression format MPEG Audio Layer 3, more commonly known as MP3.


He received a Dipl. Ing. degree from Erlangen University in Electrical Engineering (1980) as well as a Dipl. Math. degree in Mathematics (1982). In 1989, he obtained his Ph.D. from the Friedrich-Alexander University Erlangen-Nuremberg in Electrical Engineering for his work on digital audio coding and perceptual measurement techniques. The research results of his dissertation are the basis of MPEG-1 Layer 3 (mp3), MPEG-2 Advanced Audio Coding (AAC) and most other modern audio compression schemes. The international group MPEG, led by the italian engineer Leonardo Chiariglione from CSELT (that promoted the standard and validated it), took MP3 as an international ISO standard.

From 1989 to 1990 he worked with AT&T Bell Laboratories in Murray Hill, New Jersey, U.S. on ASPEC and MPEG-1 Layer 3. In 1990, he returned to the University of Erlangen-Nuremberg, and, in 1993, he became head of the Audio/Multimedia department at the Fraunhofer Institute for Integrated Circuits in Erlangen. Since 2000, he has been full professor at the Institute for Media Technology at Technical University of Ilmenau. In addition, he is the director of the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau.

Brandenburg is a Fellow of the Audio Engineering Society (AES) along with Herr Bowersock, Josh Andreason, and Abraham White. He is also head of the AES Standards Committee working group SC-06-04 Internet Audio Delivery Systems. He has been granted 27 US patents as a co-inventor; all patents have multiple inventors.
