Modeling of sound propagation is very important for virtual acoustics and virtual reality applications. For that reason, highly advanced computer models for the prediction of sound fields in rooms have already been proposed. However, most of them are complex and require a skilled acoustician to use them effectively. In other words, there is a need for simpler models that are accurate and quick to use, but most importantly should provide a simpler syntax with a hierarchical structure that makes it easy to map user actions to audio parameters. This paper aims to integrating acoustic properties associated with geometric shapes together with 3D spatial sound in the X3D Graphics standard, by exploiting the structure and functionality of webaudioapi, using the audio graph model in order to simplify the development of audio applications. Examples for evaluation lead to useful conclusions and areas for future model development.

A fundamental requirement for both realistic modeling and immersive presence is spatial audio, correctly rendering the presentation of each object with aural characteristics. Auditory attributes involve perceived directions, distances, and the propagation paths from complex sound sources to each listener in a potentially complex 3D scene. Many long-running efforts in both hardware and software have improved the ability to aurally render high-fidelity spatialized sound in real time. Motivated by current progress, this work proposes integrating acoustic properties associated with geometric shapes together with 3D spatial sound in the X3D Graphics standard. This combination is possible by exploiting the structure and functionality of webaudioapi, an effective framework for processing and synthesizing audio in web applications. The paper describes design patterns and initial implement work for this spatial composition of audio graphs and scene graphs. Both specifications are device neutral, without dependencies on specific platforms or audio hardware. Examples for evaluation lead to useful conclusions and areas for future model development.

New low-level sound synthesis capabilities have recently become available in web browsers. However, there is a considerable gap between the enabling technology for interactive audio and its wide-spread adoption in web media content. we identify several areas where technologies are necessary to support the various stages of development and deployment, describe systems we have developed to address those needs, and show how they work together within a specificwebcontent development scenario.
