This chapter illustrates example scenes for generating and acoustically propagating audio as spatial sound, focusing on advanced capabilities provided by the W3C Web Audio API.

These examples are based on initial implementation efforts at Spatial Sound in X3DOM with Web Audio API, extracting and validating the X3D models which are contained in those HTML pages. They implement the X3D4 Sound Component.

X3D Scene Authoring Hints: Audio and Sound provides numerous links to further sound-related assets for Web authors.

Of additional interest are corresponding paper and tutorial given at the twenty-fifth anniversary Web3D 2020 Conference. Here are local copies of these assets.

In this example the camera is the ears of the user. So, if the trackCurrentView field from ListenerPointSource is TRUE then position and orientation matches the users current view
