Welcome to the International Audio Laboratories Erlangen

Being the birthplace of mp3 and AAC, Erlangen has a long history in audio coding research. Initiated in the late 1970s by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) professor Dieter Seitzer, the coding research was continued by scientists from both the university and the Fraunhofer Institute for Integrated Circuits IIS. Fraunhofer IIS also took care of the product development and the successful market introduction of the resulting audio codecs that have become indispensable nowadays. The AudioLabs® mark a new era of this fruitful collaboration between both institutions. FAU provides six professorship positions while Fraunhofer IIS fuels the AudioLabs® with its undisputed know-how in audio engineering and its world-class multimedia infrastructure, including sound labs, digital cinema lab etc. and also provides funding. Today, a team of 50 globally-renowned scientists, post docs and PhD students from Fraunhofer IIS and FAU conducts cutting-edge research and shapes the future of audio and multimedia. They bring together scientific ingenuity and the know-how to make new ideas a commercial success.

Snapshot of Current Research

Score-informed Music Separation and Restoration applied to Drum Recordings

snapshot This research investigates the suitability of Non-Negative Matrix Factor Deconvolution (NMFD) for source separation of drum solo recordings (especially breakbeats) into their constituent drum sound events. Intuitively speaking, NMFD models the drum recording with a small number of template sound events, ideally corresponding to the sound of individual drum instruments. The accompanying website lists several audio examples of decompositions of iconic breakbeats as well as selected items from the "IDMT-SMT-Drums" test set. This research has also been presented in a talk on "breakbeat science" given by Jason Hockman at the Ableton Loop conference (see the video).
