Research and teaching of the Audio Communication Group is dedicated to the communication of music and speech in acoustical or electro-acoustical systems. This includes topics such as electroacoustic recording and reproduction technologies, 3D audio by binaural technology or sound field synthesis, technologies for the composition and realisation of electroacoustic music and sound art, and empirical approaches to study the reception of media content.

The department runs two electronical studios with a 12 resp. 8 channel loudspeaker setup, a wave field synthesis laboratory with 192 channels, a 3D media lab including 180° panorama projection and dynamic binaural reproduction, and the world's largest wave field synthesis installation with 832 channels and 2704 loudspeakers. The audio communication group is organizing the master program in Audio communication and technology and contributes to the Tonmeister studies organised by the University of the Arts (UdK) Berlin.
