If I may grossly oversimplify your argument Axon, you're partially arguing that he's choosing an extreme edge case to test. However, if his intent is to map the boundaries of audibility, wouldn't an edge case be acceptable? I find the conclusion that ultrasonics are perceptible fascinating, and if he's found a case in which they actually are audible, should we not hear it out? Even though it does not represent most cases, if they are truly audible in this case, isn't that worth considering?

As an archivist, I want transparency in all cases, so I don't have to worry about the edge cases. That's why I use FLAC and not MP3. If there is any case where 44.1kHz is not sufficient, isn't that worth devising solutions for?

I think his results are really interesting, but to an archivist, they're not relevant until they're shown to apply to something approaching actual audio. After all if you just want to store square waves, you shouldn't be using PCM in the first place because of its nasty requirement that signals be band limited . . .

…Because other sampling methods don't require band-limited signals?

For archival purposes there is a decent argument for going beyond redbook "just in case" ... Perhaps the lizard people who will take over the earth after we nuke ourselves will have decent ultra-sonic hearing and want the full experience? It's not like the behaviours of professional archivists have much relationship to the behaviour of normal people anywhere else. (Or will you be micro-scribing my message onto a nickel plate?)
