My initial thought was that this is a bad source, cause whenever you got no sign of life above 16K (and it's not a mono or MD recording for instance), that's never a good thing. Thanks for your help!
You're welcome... what I'm looking for is the telltale "blocks", when you zoom in and these are visible then it's positive that it's a lossy source. eg:

Yours is very strange, it seems to cut straight across twice (??!!), once at about 15.2kHz, then again at 16kHz (the blue part). I can't see the blocks here, so I can't say for sure that it's lossy. Perhaps this was over-nr'ed? I'm stumped. It looks a little like FM, but normally there'd be noise at the top of the spectrum and the reddish parts don't cut off so abruptly. Anybody got some 2nd opinions on this one?

If you want, you could also attach a 4-5 second FLAC in a .zip here, too, I might be able to tell more if I can hear just a little of it.
