Construction of 3-D Audio Systems: Background, Research, and General Requirements

摘要

Over the last few years one of the most promising advances for Human Machine Interfaces (HMI) has been the development of 3-Dimensional Audio (3-D Audio). The Air Operations Division of DSTO has been engaged in an extensive research program developing 3-D audio for the military aviation environment. This document is intended to provide some general background and to list some of the broader requirements that need to be considered when designing any 3-D audio system. Included in this report is some background information describing the perceptual basis of 3-D audio, a brief review of some of the research associated with the development of 3-D audio, a discussion of the hardware and software requirements for the implementation of 3-D audio, a brief survey of current commercial 3-D audio systems, and some discussion of the issues that require further consideration.
