Well, that certainly explains a bit. Like why everyone looks at me
funny when I say "can you turn that TV off?" even though it isn't
displaying anything... I didn't realize that the sound being
generated had quite *that* high of a pitch. But hearing it does
require that there aren't a lot of other sounds masking it, which
ought to be the case in a given MP3, unless someone is trying to make
a collection of "painful sounds." So if cutting the frequencies off
at 16KHz does in fact free up some bandwidth, I say go for it. [Well,
go for it as a command-line switch, at any rate.]
