Realisation of vitual headphones

The aim of this project is to realise a virtual earphone. A measurement system is implemented as a GUI (Graphical User Interface) in Matlab. The system measures the HRTFs (Head Related Transfer Functions) from the acoustic sources to the microphones of a dummy head and calculates the IHRTFs (Inverse HRTFs). After that the acoustic sources for the sound reproduction can be calculated from any stereo signal. Wave field synthesis positions these sources as virtual sources around the head. The quality of the virtual earphone system has to be evaluated for different array geometries of the secondary sources and for different parameters. The project is carried out at IRT in cooperation with IEM.
