[x3d-public] Fwd: Sound and Audio extensions in X3D4

[Don Brutzman]

Briefing opportunity: this week's X3D Working Group teleconference features Efi Lakka reviewing significant changes to X3D Sound Component for spatialization of sound and alignment of audio capabilities with current Web capabilities.  This builds on capabilities first reported in the Web3D Conference held in Crete a few years ago.  Her work includes updates to the X3D Sound Component (as a github pull request) plus demo scenes implemented in X3DOM.

Synopsis of current activity attached.  Discussions will include next steps for additional implementations.

Of significant note (I think) is that this work is aligning with W3C standards for HTML5 and audio.  Major capabilities are emerging there.
