ABSTRACT
The experience and use of three-dimensional (3D) sound in human culture has always been tied to the technological capabilities of the generation hearing it: for most of human history, this technology was limited to architectural spaces and music composition. Since the 19th century, more advanced technologies have allowed both the more accurate representation of real-world soundscapes as sonic spaces that have no correlate in physical reality. The other area focusing on 3D sound currently is the field of virtual auditory spaces (VAS), which may be used for either virtual reality simulations or augmented reality integrations of 3D sound into the listener's existing auditory environment. In contrast to the musical front, these applications' goals fundamentally require convincing spatial immersion, elevating the importance of space above that of frequency or time in many cases. The effect of physical space is not limited to the perceived physical locations of sounds—different spaces can also affect music in the time domain or frequency domain.
