Small Mistype in Web Audio API W3C Working Draft 13

Hello,

Been reading the Web Audio API W3C Working Draft 13 and found a small
mistype on the "9. Channel up-mixing and down-mixing" -> "Up Mixing" ->
"Quad up-mix:".

It says:
4 -> 5.1 : up-mix from *stereo* to 5.1
        output.L = input.L;
        output.R = input.R;
        output.C = 0;
        output.LFE = 0;
        output.SL = input.SL;
        output.SR = input.SR;

And I believe it should be
4 -> 5.1 : up-mix from *quad* to 5.1
        output.L = input.L;
        output.R = input.R;
        output.C = 0;
        output.LFE = 0;
        output.SL = input.SL;
        output.SR = input.SR;

I'm sorry it you are not the one that I should contact for that kind of
thing, but it was the only contact that I've found on the page.

Best Regards,

Oliver Drummond
