Multichannel layout?

[[)370|\|470!2]

It's a shame, that here is no such faq yet. Someone plz make one =)

Afaik, there's at least 3 tipes of layout for AAC, AC3 and OGG (5.1)

AAC => FL, FR, C, LFE, SL, SR;

AC3 (and WMA) => FL, C, FR, SL, SR, LFE;

OGG => ?

Correct me, if i'm wrong and btw, what's OGG 5.1 mapping?
Is it possible to modify mapping w/o reencoding?

OGG => ?
same thing as AC3. btw, it was in BeSweet FAQ. :search:

Is it possible to modify mapping w/o reencoding?
maybe with ac3filter or ffdshow audio filter...

You mean this?..

6chwav/6chaiff

g:\channelFL.wav
g:\channelFR.wav
g:\channelC.wav
g:\channelLFE.wav
g:\channelSL.wav
g:\channelSR.wav

ac3/ogg

g:\channelFL.wav
g:\channelC.wav
g:\channelFR.wav
g:\channelSL.wav
g:\channelSR.wav
g:\channelLFE.wav

But i've been searching for an AAC reference...
Figures it's the same that 6chwav/6chaiff, right?

Third, a .mux file for aac/mp4 output file looks like this :
C:\output-C.wav
C:\output-FL.wav
C:\output-FR.wav
C:\output-SL.wav
C:\output-SR.wav
C:\output-LFE.wav
by assuming that the files are located in C:\. Note also the channels order.

If you have some troubles with this, I fear that your problem doesn't concern BeSweet..

What is this mapping good for? Psytel aacenc, i guess? lol. Not good for Nero though.
Ah, and one more: how channel mapping is organized? Is it in file structure or
only the header? Or is it vary from-to formats?
