“Wrapping” X3DOM around Web Audio API

Abstract

-Spatial sound has a conceptual role in the Web3D environments, due to highly realism scenes that can provide. Lately the efforts are concentrated on the extension of the X3D/ X3DOM through spatial sound attributes. This paper presents a novel method for the introduction of spatial sound components in the X3DOM framework, based on X3D specification and Web Audio API. The proposed method incorporates the introduction of enhanced sound nodes for X3DOM which are derived by the implementation of the X3D standard components, enriched with accessional features of Web Audio API. Moreover, several examples-scenarios developed for the evaluation of our approach. The implemented examples established the achievability of new registered nodes in X3DOM, for spatial sound characteristics in Web3D virtual worlds.

Extending X3D Realism with Audio Graphs, Acoustic Properties and 3D Spatial Sound

“…In order to verify the validity of our design, the new registered nodes and the proposed structure were applied to several experiments -examples that were already implemented in previous work [Stamoulias et al 2015] continue to be updated. The first example evaluates the attenuation of one sound source, in a 3D scene.…”

Designing a Virtual Reality Platform to Facilitate Augmented Theatrical Experiences Based on Auralization

“…The implementation takes advantage of recent improvements in web browser technology (HTML5 and the embedding of a number of new libraries that implement new objects and services). Previous work [18] introduced an extended version of X3DOM platform that incorporates spatial sound capabilities within a virtual scene using the widely supported Web Audio API proposed by the World Wide Web Consortium (W3C) and implemented in all browser platforms.…”

Spatial Sound Rendering – A Survey

“…Also, audio channels can have 3D distribution according to the position, speed or direction of the viewer and the sound source. Different from the above publications, the first systematic study for the implementation of spatial sound in web presented from the group of Stamoulias [116] in which they enriched the X3DOM framework (an open source JavaScript framework, used to create declarative 3D scenes in Web pages) with spatial sound features, using both the X3D (a royalty-free ISO standard XML-based file format for representing 3D computer graphics in web) sound nodes and the structure of Web Audio API.…”
