Digital Audio - Psychoacoustical Localization of Sounds within the 3- Dimensional Soundstage

As objects vibrate, they cause changes in the air pressure, which our ears perceive as sounds that could be translated by our brains as speech, music or noise (Garba 2007b). The four basic characteristics of sound include frequency, amplitude, harmonics and direction from which a sound is coming. The frequency describes the rate at which the air vibrates per second, measured in hertz (Hz). Amplitude is a measure of the loudness of the sound, while harmonics are the exact integer (or whole number) multiples of the fundamental frequency that are responsible for sonic distinction known as timbre ((Garba 2007b), (Atkinson 2006)). The aforementioned premise establishes the localization of sound within a given 3dimensional space known as soundstage. This paper, therefore, addresses some practicable solutions with regard to the theories, laws, principles and systems of psychoacoustical localization of sounds during recording, mixing and mastering in digital audio production.
