A 3D real time rendering engine for binaural sound reproduction

Proceedings of the 9th International Conference on Auditory Display (ICAD), Boston, MA, July 7-9, 2003.A method of computationally efficient 3D sound reproduction via headphones is presented using a virtual Ambisonic approach. Previous studies have shown that incorporating head tracking as well as room simulation is important to improve sound source localization capabilities. The simulation of virtual acoustic space requires to filter the stimuli with head related transfer functions (HRTFs). In time-varying systems this yields the problem of high quality interpolation between different HRTFs. The proposed model states that encoding signals into Ambisonic domain results in time-invariant HRTF filters. The proposed system is implemented on a usual notebook using Pure Data (PD), a graphically based open source real time computer music software

Musica viva in schola XXVII.

Title in English: Musica viva in schola XXVII. The proceeding from the jubilee 30th international music-educational conference Musica viva in schola continues the tradition of publishing MVIS conference papers from previous years. The contributions respond to current issues in music education and the arts and culture, including modern approaches in education and research projects. In addition to the above, the current year also focuses on musical traditions in music education. Authors include academics and researchers, as well as music didactics, practitioners, and representatives of national and international music education societies
