</div></div>Why do you think they should be? What<br>
advantage would this give? Also, I don't<br>
believe it is only 7 and 8 channel mappings<br>
that are undefined in FLAC. I don't see<br>
a mapping for *any* number of channels.<br>
<br>
At the moment, the channel order/mapping on<br>
output are the same as on input. This means<br>
that you can use any mapping you feel is<br>
appropriate. To see a list of mappings which<br>
have been specified elsewhere, visit:<br>

Scroll down to near the bottom for 7.1 and 8.0<br>
mappings.<br>
