Aureal’s
A3D Interactive
is a positional 3D audio technology.
Positional 3D audio—also known as interactive 3D audio—allows
for interactive, on-the-fly positioning of sounds anywhere in the
three-dimensional space surrounding a listener. Support for this
technology has been incorporated into software applications such
as video games to create a natural, immersive, and interactive
audio environment that closely approximates a real-life listening
experience.
Your MX300 audio system aims to digitally reproduce a highly
realistic sound field. To achieve the best possible effect, an A3D
system recreates all of the listening cues to which a human ear
responds: outer ear effects, occlusions, reflections, and so on. A
typical first step to building such a system is to capture the
listening cues by analyzing what happens to a single sound as it
arrives at a listener from different angles (see following
illustration).
