What is Sound Spatialization

What is the real potential of computer science when applied to music? It is possible to synthesize a “real” guitar using physical modelling software, yet it is also possible virtually to create a guitar with 40 strings, each 100 metres long. The potential can thus be seen both in the simulation of that which in nature already exists, and in the creation of that which in nature cannot exist. After a brief introduction to spatial hearing and the binaural spatialization technique, passing from principles of psychoacoustics to digital signal processing, the reader will be included on a voyage through multi-dimensional auditory worlds, first simulating what in nature already exists, starting from zero and arriving at three “soundscape dimensions”, then trying to advance the idea of a fourth “auditory dimension”, creating synthetically a four-dimensional soundscape.
