Virtual Reality is one of the hottest buzzwords today in electronics industry. Until recently, the focus of these efforts was in providing stereoscopic three-dimensional graphics to stimulate our sense of vision. However, to create believable worlds, visual cues are not sufficient, the field of auralization, -three dimensional sound- is necessary. There are a number of motivations for developing auralization systems in addition to the advent of virtual reality. The three dimensional processing adds an auxiliary creative element to be manipulated by the commercial musician or record producer, providing a new realm of entertainment to explore. In this paper, a tridimensional sound system for performing static sound source placement with headphone playback using the filtering by HRTF is developed.
