The implementation of a real time 3D rendering engine for sound reproduction via headphones is presented. The system is implemented using Pure Data (PD by Miller Puckette) an open source real-time computer music software. To improve source localization capabilities head tracking as well as room simulation have to be incorporated. The proposed system uses a virtual ambisonic approach that results in time invariant HRTF filter.
