Files have been replaced, there is now one file for this test with varying
levels of wasted bits. At the end it also has a differing number of wasted
bits between the left and right channel. In other decoders this has been a
problem in the past. It now changes 0-0, 1-1, 0-0, 1-1, 3-2, 2-3, where
each pair is the number of wasted bits for the left and right channel. I'll
send new patches in a moment.
