DAB sounds far worse than FM
Hearing is believing just how poor DAB really is.

Digital Satellite is far better for radio than DAB for home listening

So you managed to work out what he was saying. Well done.

I recommend hearing the windows128, else the mpeg128. Its a fraunhofer
codec at the moment but soon well switch to a custom codec with a 20kHz
cutoff @ 128k (not lame, lmao) The codec is a huge huge issue with alot of
dab, alot of webcasters just dont know how to listen for quality. Another
big thing is a properly balanced sound so that the codec, which works by
using a masking curve based on the ear, can better represent the original
frequencies.
I do agree with the bitrate issues, we'll be rolling out a new 196k mpeg4
stream sometime after we get the new password login stuff done, but that
will improve quality even more for our supporting listeners, using a
multi-platform system.
Weather dab does or doesnt sound better than fm it does sound different,
especially considering the unpredictability of the deemphasis from one
reciever to the next, and the lack of knowledge about codecs amongst typical
dab broadcasters. Pleanty of casters dont know about ogg for instance (
www.vorbis.com ) or p2p broadcasting technology.
me 2cents,

Don't panic, I don't think anyone here is misled by Steve. We all
understand that DAB is potentially better than FM and as implemented
across most of mainland Europe, it is. But here is the UK where we
have deaf and greedy fuckwits running our broadcasting organisations
things are rather different.
> poor audio on radio 2 and some dab stations in mono
It's unfair to single out R2; there's nothing wrong with R2's audio as
fed to the encoder - it sounded great a year ago before the
bit-burgling started. Most independent stations are far worse.

But the public do care about price, and they're not going to pay a x5 premium
for something which is no better than its predecessor, manufacturers know this,
that's why they aren't bothered to integrate tuners into standard kit.
Az.
Is it panto season already?!
Oh yes it is!
DSAT is fine coming from a telly, but painful to listen to closely.
DAB uses even lower bit rates, I shudder to think how bad it is.
Fine for the car, I suppose.
*sigh*

Music downloaded off the internet is mp3, DAB uses mp2. mp3 is about 33%
more efficient than mp2 at low bit rates so 128kbps mp3 is about the
equivalent of 160kbps mp2.

Correct.

I think they know what is what, but they're doing the brainwashing. That is
iIf they are a DAB expert. Some of the DAB industry don't know what they're
talking about.

Er, right. Fantastic. Why not just drop everything to the lowest common
denominator crap because Joe Average doesn't understand digital audio? Sod
that.

That is no excuse to use crap audio quality on DAB which was supposed to
offer a step change improvement in the audio quality I'm afraid.
Just!
I think our friend Neil has returned to be honest.
Then get a DSat receiver with a digital audio output.

It is bad.

Quite....
Most broadcast music is unimaginative rehashed trash anyway.
Just watched Top Of The Pops, creativity alive and well, HA. Westlife
number one for the 11th time...

Yes, but that's MPEG1-LayerIII, which at 128k is marginally better than
MPEG1-LayerII which is what DAB uses. Then you have the crap compression
etc.
