Music Technology and Digital Musicology Lab

The Music Technology and Digital Musicology Lab (MTDML) is part of the Institute for Musicology and Music Pedagogy at the University of Osnabrück.

A research focus at MTDML is on Acoustical Extended Reality and Computer Audition. Acoustical Extended Reality uses virtual, augmented or mixed reality technologies in connection with acoustic (here mainly: music-related) research questions. Computer Audition uses methods from the field of artificial intelligence to obtain semantic information from audio files.

Other related fields of research are musical acoustics, music perception and electronic sound generation / musical interfaces. The MTDML benefits from the lively exchange with the musical ensembles, choirs, bands and symphony orchestras located at the institute.
