From the actual iBiquity handbook the rate is 96Kbps. There is no
"98Kbps" spec in the system. So going with the real figure, we find that
the bit rate is approximately one-fifteenth that of an ordinary CD, the
CD including forward error-correction. Amazing! "Virtual CD quality"
with seven percent of the data used by the CD. And using a ten-year-old
codec at that. You don't have to be an audio engineer to discover why
"HD Radio" sounds the way it does.

Well over here a broadcaster claims that a 64K Mono channel offers
superior sound quality thats Crystal Clear;!...

Who was it who said tell the people lies often enough and they become
the truth .. Dr Goebbels was it or someone similar?..

64K mono would be about as crystal clear as 128 stereo, no? That's
crystal clear to most people. I listen to 32 K web streams which are
great for all but most critical applications.

When those first iPhones came out, a guy in NYC had just bought one.He
was taking the elevator down to the first floor, he had his brand
spanking new shiney as a new born baby's ass iPhone in a string handle
shopping bag.The elevator door opened, he stepped out, a MOFO grabbed
the guy's shopping bag, nearly ripped off one of the guy's fingers
because it was tangled up in the shopping bag string handle.
BAN ALL STRING BAG SHOPPING BAGS! THEY ARE DANGEROUS!

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

Stainless like this http://bit.ly/fhpoHp
to ensure your purchases arrive home with you?

As in I don't wear gold.

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.

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.

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

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

MP3 is Mpeg 1. It seems to do OK.
