This paper presents a library for programming 3D binaural sound reproduction systems using Pure Data (pd), an open source computer music programming language. The theory that forms the basis of the proposed library is an improved virtual Ambisonics approach. Using this approach provides computationally efficient implementation of multiple moving sound sources, room simulation, head tracking and time varying listener positions in virtual space. Furthermore, simple GUI objects for controlling parameters are implemented to provide easy to use environment.
