Workshop on HTML.next for Games
Surround sound support
Use case
As 5.1 speaker arrangements become common in homes, games that feature a virtual world use surround sound effects to increase the realism of the action taking place in the scene.
Gap analysis
Developments within the Audio Working Group<http://www.w3.org/2011/audio/> should help create a basis for audio synthesizing using JavaScript which is not restricted to any particular speaker setting in particular. Higher-level functionality to place a sound in a surround environment may be needed.
Possible solution
The Web Audio API<https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html> draft proposal by Google provides the basis mentioned above. The Audio Data API<https://wiki.mozilla.org/Audio_Data_API> by Mozilla is more basic but compatible with other uses of media streams, e.g. to enable real-time communications. The Web Audio API could be added on top of the Audio Data API. Further higher-level functionalities might help generate surround sounds in real-time from JavaScript.
Related group
Such discussions are in scope of the Audio Working Group<http://www.w3.org/2011/audio/>.

I noticed that there is no explicit requirement of multiple channel support in the Use case and Requirement.

Should it be added in the requirement? Any opinion?
