AES Germany Research Colloquium #4: From mp3 to PARty

The new AES Germany Research Colloquium aims to provide a platform to discourse on a specific audio topic and create a bridge between basic research, manufacturers and users in audio technology.

From mp3 to PARty. How signal processing, psychoacoustics and machine learning fit together

The talk will start with a brief historical overview: How mp3 and other audio coding formats got developed. To advance this technology, a lot of knowledge about our ears has been necessary.

Since then, we have learned much more about our ears and brain, as well as how we listen to the world around us. Cognitive effects have become more and more important. We really hear what we expect to hear. All this has been used in a lot of research over the years.

Currently, an important topic of our research in Ilmenau is finding out how we can reproduce immersive sound, the feeling of “being there”, over headphones. After approximately 50 years of research by others and contributions from myself, we can finally claim that we have solved this problem. The process of how we achieved it and what means we used will be included in the talk.

The talk will conclude by presenting ideas about future applications that may initially sound like science fiction, such as PARty, but we are working to transform them into reality.

Prof. Dr.-Ing. Karlheinz Brandenburg – CEO of Brandenburg Labs GmbH and Senior Professor at the Institute of Media Technology at Technische Universität Ilmenau

Karlheinz Brandenburg received the Dipl.-Ing. and Dipl.-Math. degrees in electrical engineering and mathematics and the Dr.-Ing. degree in electrical engineering from the Friedrich-Alexander-Universität (FAU), Erlangen-Nürnberg, Germany. He is currently Senior Professor at TU Ilmenau, Germany and CEO of Brandenburg Labs GmbH, a startup company specializing in immersive audio technologies. Following times as a Postdoctoral Member of Technical Staff at AT&T Bell Laboratories in Murray Hill, USA and again FAU he joined the Fraunhofer IIS, Erlangen, as head of the Audio and Multimedia Department. He is the founding director of the Fraunhofer IDMT, Ilmenau where he retired in 2019. For his pioneering work in digital audio coding (as a main contributor to the mp3 and AAC audio coding standards), perceptual measurement techniques, wave field synthesis, psychoacoustics, and analysis of audio and video signals he received many awards.

Join Meeting

The colloquium will be held in English with a presentation of 60 minutes, followed by a 30-minute discussion.

Link to register in advance for this meeting. After registering, you will receive a confirmation email containing information about joining the meeting.

The Meeting Format: We will be hosting this meeting using Zoom. After registering, you will receive a confirmation email containing information about joining the webinar. For most participants, audio and video are muted during the presentation. In the discussion they can be unmuted (indicated by the raised hand function). This will be explained again at the beginning of the meeting. For a better quality we suggest to use a headset with microphone. The presentation will be recorded. By turning on your camera you are consenting for your image to be used in a photograph of the event.
