Audio-ISSUE-95 (ChannelLayouts): Channel Layouts are not sufficiently defined [Web Audio API]

http://www.w3.org/2011/audio/track/issues/95

Raised by: Philip Jägenstedt
On product: Web Audio API

This section admits that "Other layouts can also be considered." It should be defined exactly which channel configurations must be supported.

It would also be desirable with a terminology section to include things like the channel abbreviations (M/L/R/SL/SR/C/LFE) and less obvious channel configurations like "Quad".

This was discussed during the 2012-10-17 teleconference. It was proposed that there should be a (read-only) attribute defining the channel layout. 

The attribute would have values from a pre-set list, small to begin with: mono, stereo, quad, 5.1 - plus an extra value for "other" layouts. These "known" layouts would have each channel numbered in a specified way. 

This solution was preferred to a more complex solution of having the layout defined through a channel dictionary.
