| Outline of Final Research Achievements |
The main goals accomplished during this project are summarized as follows. 1) New mathematical methods to capture and reproduce spatial sound at far and near distances were formulated and evaluated. 2) A collection of head-related transfer functions was created. 3) A virtual environment for psychophysical experimentation was assembled. The system captures and reproduces 3D ambisonic audio and 360 video. 4) A collection of immersive contents for headphones and head-mounted displays has been created. 5) The international collaboration with Tsing Hua University and Hannover Medical School has been initiated to explore the computational aspects of the auditory brain. 6) An international workshop has been organized and held in Lima, Peru, to present the achievements of this project. This was done in collaboration with "Universidad de San Martin de Porres" and "Fundacion Telefonica".
