I've read the technical paper and it's filled with logical contradictions. 
They claim the human ear is some delicate construction which can detect 
the tiniest distortion in audio, and then they go on to say that they 
throw away the LSB of the audio signal to store their sideband data 
because the human ear can't hear it.

Well, which is it, AES? Either the human ear is delicate and can hear 
every tiny distortion, or the human ear isn't that accurate and throwing 
away LSB isn't a big deal.

You can't have it both ways, AES. Your HDCD looks bogus to me.
