Book Description
It is anticipated that 3-D sound will become a major component in virtual reality environments. In this thesis, we investigate the development of a Windows(TM) 3-D sound system using binaural technology. This work should eventually be integrated in complex virtual environment software. The 3-D sound effects are achieved by applying a filter pair representing audio cues from a specific point in space to the left and right channels of headphones. As a first step, an offline 3-D audio file generation system is developed, and effects such as sound reflections in a virtual rectangular room are added to this system. The real-time implementation is considered next. The first approach tested for the real-time implementation uses the time domain convolution of a sound source signal with head-related transfer functions, but the computational load of this approach is such that it cannot run in real-time at audio sampling rates. As an alternative, a second approach with a Fast Fourier Transform overlap and save technique is used to reduce the computational load, and a real-time implementation at audio frequencies is therefore successfully achieved.

A Framework for Interactive Three-dimensional Sound and Spatial Audio Processing in a Virtual Environment
Author: Michael Wozniewski
Publisher:
ISBN:
Category : Shared virtual environments
Languages : en
Pages : 106
Book Description
"Immersive virtual environments offer the possibility of natural interaction within a virtual world that is familiar to users because it is based on everyday activity. The use of such environments for the representation and control of 3-D sound remains largely unexplored. We propose a novel paradigm for interacting with sound and using virtual space as the medium for spatial audio processing. A supporting software framework has been developed that provides functionality not available in other 3-D audio systems, including powerful control over the directivity of sound and the ability to bend the rules of physics for musical purposes. These features provide the necessary tools to create virtual scenes for audio engineering, musical creation, listening, and performance. Tracking technology allows the use of gesture-based interaction techniques to control the environment, resulting in many possibilities for novel applications." --
