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.
One central problem in music signal processing is the decomposition of a given audio recording of polyphonic music into sound components that correspond to musical voices, instrument tracks, or individual note events. One main challenge arises from the fact that musical sources are highly correlated, share the same harmonies and follow the same rhythmic patterns. In current research, we use additional cues such as the musical score to support the separation process. The score also provides a natural way for a user to interact with the separated sound events.
