In the first clip, the hihat glissando rises faster and the "C"
is more noisy and has a slight differente stereo image. Try to
listen it in mono or with a stereo enhancer to locate what's
different, then try to ABX it again :))

MP3 artifacts are easy to locate at 128kb/s. Vorbis does a much better
job. If you don't have the original to compare, it's impossible to tell
if the sound has been compressed.

<p>Bye.
