RE: about multiple channel support in the Use case and Requirement

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.

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?
