DAB R3 balance
 

I'm getting poor R3 DAB quality right now (2005/02/10-20:00). Normally it
sounds exactly like FM except no background noise, but since last night
the frequency extremes are missing. FM is OK, so the audio stages of the
tuner are working properly, and I've fed the digital output into a
Minidisc recorder to use a different DAC and the muffled effect is
present. Hard to see what's left in the receiver (Sony ST-D777ES) for it
to be a fault there.

Anyone else hear this?

Could be worth your time to download the free 4n1tool[1].zip from the
web. It'll give you a spectrum analyser and other goodies with which you'll
be able to measure what's going on.

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

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

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;(

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.

Perhaps Jim Lesurf would have a listen and comment?

I don't have the very best MP3 codecs on this computer, but most of the
things I download sound ok.

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

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.

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

The MP2 file is the raw bitstream recorded directly to hard drive. The
FM was recorded from my Denon tuner via my sound card and then encoded
at high bit rate (VBR, IIRC).

I know, relatively poor reception at the time.

It depends on the MP3 software you're using to playback. Some of the MP3
players hide the splat, while others don't.
