Whenver I've compared R3 DAB with R3 FM, FM has always sounded
better.

Download and listen to the R3 DAB and FM recordings from my samples
page:

http://83.142.53.30/~digital/R3_DAB.mp2 (1.5 MB)
http://83.142.53.30/~digital/R3_FM.mp3 (2.2 MB)

And R3 is the best sounding station on DAB, which doesn't say much
for the other ****e.....


Actually the FM has a very high level of hiss, and a generally harsh
and unpleasant sound. The DAB is far better.



I disagree.

Just have done. Apart from one being MP2 and one MP3, there are splats
on the DAB sample which you simply don't get in reality, and some form
of heterodyning on the FM one which I've never heard before. Sounds
like a possibly dodgy land line? Or something going on at low level in
the recording which is well and truly upsetting the coding - as it
shows up on the DAB sample as well, but in a different way.


Can't say I've noticed the splats on the DAB one, or the heterodyning on
the FM one, but from that site on both DAB and DTV there is something
twiddling away on the quiet parts. But as I do my critical listening in
the ESL63's (I've only used phones) as I've not got this connected to
the PC as yet.


I listened at a level I'd use for problem checking - and nothing like some
would use. And not on my main system.

There is a bit of background hiss but the sound on both seems a tad
unpleasant.....


Very much so. At first, I thought I had a different problem, so listened
to a few known MP3 files I had on HD. Then did another download. And again.
Still the same, so concluded they are naff samples - or something wrong
with the playout.

Really. How did you interface a DAB tuner directly to your computer HD?

The FM was recorded from my Denon tuner via my sound card and then
encoded at high bit rate (VBR, IIRC).


You give the make of the tuner, but not the soundcard? Considering most
soundcards are the spawn of satan? On analogue?

I know, relatively poor reception at the time.


Oh dear. Now I know my memory is poor, but I think I remember you having a
go at me when I suggested that *many* have poor FM reception, the
artifacts of which would be in the main sorted by DAB? And that you said
that my poor reception of FM - shared by about 1,000,000 others in South
London - and gawd knows where else - made my views worthless?
But you try to prove your views by using a dreadful recording of both DAB
and FM on your website. WTF are you on?

Anyway, the temporary change in R3 DAB sound, which is what this
thread was about, has now (morning of 12 Feb) gone away.

I think the BBC must have switched R3 to a low bit-rate for a while.
Let's hope they don't make a habit of it. It's bad enough having to
accept a measly 192kb/s.

Anyone else hear this?


YES. I just did a check (2005-02-11 at 13:45) and yes, R3/DAB is very
muffled at the moment. I just compared it to R3/DTTV. Up to now the two
have been indistinguishable (well, apart from the extra delay on DTTV).
I wonder what's happened to R3/DAB - it's horrible at the moment.


Probably had its bit rate cut to even it out with the other bit
disadvantaged channels;(


I started wondering about whether those who listen to R3 on DAB had
indeed got our come-uppance for being elitist. However it seems to be
back to normal this morning (2005-02-12 at 08:40).

The top end of R3/DAB seems to be back in place and both R3/DAB and
R3/DTTV sound the same again (as I think they should at 192 kbit/s
for both).

Both ****e as you say, but the FM is far the worse.

All DAB, DVB-T and DVB-S PC cards record the raw bitstream directly to
the hard drive. For example, all the DTT products in these section do
this:

http://www.digitalradiotech.co.uk/fr...eview_pc_cards
http://www.digitalradiotech.co.uk/fr..._usb_receivers

and the PC products on here do too:

Terratec EWX24/96. It's a good card. And yes, analogue.

The poor reception was on DAB, not FM.


And that you said that my poor reception of FM - shared by about
1,000,000 others in South London



1,000,000 people share your bad FM reception? Have you carried out a
very large poll, or something?


- and gawd knows where else - made
my views worthless?



I know there are some bad reception areas for FM. My point, which you've
conveniently omitted or forgotten, is that just because a smallish
percentage of the population do have poor FM reception is not
justification to provide low audio quality on DAB. Do you disagree?

Just to add some facts which you are probably not aware of, this page
shows the number of stations that could be transmitted at 160kbps or
above:

http://www.digitalradiotech.co.uk/wa...x_capacity.htm

Altogether, 183 stereo stations could be transmitted on DAB in the UK
and the only radio station that would have to be removed would be DNN,
which is the sorriest excuse for a radio station I've ever come across,
and I've never seen a good word said about it. To give you an indication
of just how ****e this station is, a few months ago someone said on
alt.radio.digital that it had been playing the previous day's news all
day; it's a news station, so you could say that its output wasn't
particularly good that day.....


But you try to prove your views by using a dreadful recording of both
DAB and FM on your website. WTF are you on?



At least I'm not defending the indefensible.

Download the other R3 sample:

http://83.142.53.30/~digital/radio3_dab.mp2 (4.4 MB)

the following 3 files are of the same recording, just encoded to
different formats:

http://83.142.53.30/~digital/radio3_fm.mp4 (6.9 MB)
http://83.142.53.30/~digital/radio3_fm.mp3 (7.4 MB)
http://83.142.53.30/~digital/radio3_fm.flac (16 MB)

Obviously the best one to download is the FLAC file, because it's
lossless.
