On space in sound

What is the function of spatiality of sound? In what ways does it contribute to the meaning of sound. Can we speak of an ontology of sound in which spatiality is one part? Is the idea of a ‘sound’ unified or does it easily break up into various parts, each of which contain important aspects of the understanding of the sound by themselves? Are certain of these parts of greater or lesser import than others? Is space or spatiality an attribute which can be modified on the sound without changing the meaning of the same sound?

There are no obviously simple answer to these questions. But given the definition ‘a high pitch sound’ the apprehension is in every respect built upon it being high in frequency. If low pitched sound is played back the definition does not match. My argument is that this is to a large degree true also of spatial properties of a sound even if we lack the quantitative definitions that for example pitch provides.
