ABSTRACT

This chapter explains the basic structure of the visual framework. There are three basic parameters of sound, which correspond to the X, Y, and Z visual axes. Panning, the left-to-right placement of sounds between the speakers, is naturally shown as a left-to-right placement visually. Sounds that are closer to people are louder and distant sounds are softer; therefore, the volume of a sound in the mix can be mapped out as front-to-back placement. One can raise or lower a sound by changing the pitch with harmony processors and aural exciters, or by having a musician play his or her instrument in a higher or lower octave or chord inversion. This becomes important when one sound masks another at a particular frequency range. Technically, it is very difficult to tell exactly where low frequencies are coming from. Low frequencies are extremely difficult to localize between the speakers.
