The Two Dimensional Spatialization of Sound package takes a single monaural sound signal and processes it to create a binaural signal that places the source of the sound at a selectable arbitrary place around the listener. The package makes use of a set of HRTF Measurements of a KEMAR Dummy-Head Model created by Bill Gardner and Keith Martin of the MIT Media Lab. The sound spatialization software is ANSI C, and can be ported to any platform which will support the sound I/O requirements. The package also includes an FFT written in well-structured C.
