This is similar problem Ive always had with SoundofSpace AAC files

usable when you broadcast multichannel material? If it does not, what's the
use of it? If it does, does it always do so, reliably? If it does but not

Hi Mick,
If you are talking about this page:
http://soundofspace.com/static/test_html5.html
then all feeds are 5.1 if you are hearing stereo it is your browser
that has decided to interpret the 5.1 feed as stereo
Thanks for helps - I could see I was accessing the ogg version in my
browsers and
when I set my speaker config correctly I can get multichanel audio
from the html5 page no
problem. Well there is a problem and that is the file order - with a
5.1 config set in OSX
im seeing a LCRLsRsLFE
Marinos - I havent a clue what a nitrate is but maybe kbs and i seem
to remember my options
in Apack being limited so i just went for the highest as ac3's are small

I don't understand the long discussion on this list. quad surround is

mp3 surround is not discrete 5.1. the most common formats for

I'd say one of the AAC profiles would still be preferrable, because

AAC is certainly an excellent codec; but can you easily play back a quad
file...? I really don't know.
I DO know VLC plays DTS straight out of the box.
The only issue with DTS files is that they are large ... and so not so good
for online distribution.
An advantage you get with DTS files

Four channel works are not common.

the order of the 5.1 is FL/FR/SL/SR/C/LF (or I am mistaken in this?) so if

I totally agree, any mention of MP3/WMA or any of the very lossy formats in the
same breath as surround cannot be taken seriously.
