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.

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.....

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

It's difficult to describe, but it's one of the unpleasant artefacts
that DAB suffers from when there's relatively poor reception.

Mine probably doesn't since it's a RISC OS one, and basic. However, I've
not had any problems with it on the many other samples I've got.

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

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.

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.
