There is an Apple store listed in my phone book, here in backwater hick
Jackson,Missy Sippy area.It is located at 1000 Highland Colony Parkway,
in Ridgeland.I reckon that is about nine something miles North of
doggy's couch.Doggy said, WOO WOO WOOF! Look it up.

64K mono would be about as crystal clear as 128 stereo, no? That's

You'd think , but DAB isn't that simple. I'm sure people more in the know
can correct me but AFAIK it doesn't simply send 2 channels of data for left
and right. I think like FM it sends mono data then some sort of difference
data which uses up much less bandwidth so a 128K DAB signal has a mono
component of something like (I'm guessing) 100K. I think this is why a lot
of people complain about the stereo image of DAB being very flat.

I'm sure wikipedia has more info.

crystal clear to most people. I listen to 32 K web streams which are
great for all but most critical applications.

DAB uses the MP2 codec from the late 80s. 32K would be unintelligable.

So all-digital does allow for more "virtual CD" quality audio channels,

Virtual CD quality at 98kb/s? Not even aac can manage that, aac+
wouldn't either as it's designed for low bit rates rather than for high
quality.

Just another example of spin, that doesn't add up when you look at the
facts.

I think Tony forgot to mention that DAB uses the mp2 codec, which is
*very* in-efficient compared to modern codecs.

At 128k in stereo, the sound quality is not much better than aac+ at 32k
in stereo. So I would expect aac+ 32k in mono to sound significantly
better than mp2 64k in mono.

KPFT is now carrying KTRU on an HD2 stream. Rice sold KTRU's frequency
to the University of Houston for a classical station.

Yeah, it's too bad that so many universities are in such dire straits
that they're giving up their radio stations, something that they can't
readily get back when the economy recovers.

It's interesting in that article that they mention what the biggest
attraction of digital radio actually is to broadcasters: "It also allows
a station to offer multiple stations to the public without obtaining a
new FCC license." While the better quality audio is often touted, the
reality is that that's just a side benefit of the digital system, the
read advantage is the multiple channels.

You're on the right lines, but I'll correct you :-)

Mid side is not available in mp2, instead is has a intensity stereo, and
it only uses it in the higher frequencies. The lower frequencies are
still in discrete stereo. The Intensity stereo as the name suggests, is
basically mono, with a parameter to select the difference in volume
between left and right channels. As far as I understand each audio sub
band would have it's own intensity stereo parameter.

A lot of the reason for the poor stereo image is that intensity stereo
doesn't preserve any of the phase information between the channels. Or
then again, perhaps it just that whole system is cr*p. :-o

Designer label shopping bags are kind of like wearing big bullseyes.
I'm a stainless steel kind of guy.

MP3 is Mpeg 1. It seems to do OK.

That digital radio Crap just doesn't cut it.It Doesn't Cut the Mustard!
