Just as a little scan trivia: the HP format is LSB-justified.<br>

Well then lets define 'depth' to be the native depth. If depth>8 then<br>
|
||
the frontend should know that one sample is send MSB justified and stretched<br>
|
||
(the way Andy described) to 16 bits. How would that sound?<br>

There are more backends then frontends :-) But I agree that was a moot<br>

point.<br>
