Of course, but an "upsampled" 128 kbit file made from a 64 kbit original
contains no additional information from the 64 kbit (unless they add
it). It's not the same work as a downsampled 128 kbit file made from a
384 kbit original.

To make this perhaps a bit more clear for those of us with a visual
bias, if you blow up a 256x256 JPG to 2048x2048, you will get scaled-up
JPG artifacts, not more detail. A blow up of a 256x256 picture is not
the same picture as a reduction from the 2048x2048 original that the
256x256 file was made from.

Cheers,
Terry
