DAB MP2 bitrate question

...

I've just been converting some music from vinyl, and I always use my old
desktop (which must be about 8 years old by now) rather than using my
laptop (which is about 3-4 years old). The reason is that the audio input
on my laptop it so sensitive that the electronics in the laptop actually
interfere with the audio.


Few laptops have any pretentions to high-quality audio. Often there is only
a microphone input, and a headphone output.

If you want to do some serious recording with a laptop you would need a
good-quality external A-D converter (probably USB connected).

That's done it - Jamie will be convinced we're the same person now!

Why, have you got an Audiophile 2496 card as well?

Just seen your other post where you say you have got the same card - I
really should stop talking to myself so much!

DAB MP2 bitrate question
 

BTW Tony, did you xpost this just to expose the sweeping assertion? I can't
see the context for it having much to do with the thread title.... IIRC
'jamie' seems to have a history of making dubious claims on the digital-tv
group... or am I confusing him with some "idiot"?... :-)

Slainte,

Jim


Actually my mistake for not making this that clear!..

Jamie over on alt.radio.digital has asserted that most all CD digital
players sound ****e owing to all the jitter they have. He thinks that
this could be eliminated by taking the audio off the CD as a datastream
and putting that onto a hard drive and replaying that via a good sound
card. This according to Jamie would then get rid of the jitter and thus
make the CD audibly better..

Just interesting to see what the contents of uk.rec.audio think of
that..


Is your assertion of that as I've described it above about right
Jamie?..

Ah!, an explanation for this thread at last!

Leaving aside, for the moment, the question of whether CD players sound
"****e" because of jitter to one side for the moment, the mention of a
hard-drive seems singularly inappropriate. Since data is written to, and
recovered from, hard drives in blocks, a pretty substantial RAM buffer is
needed between the drive and the sound card. The effects of jitter on the
audio can be eliminated fairly easily by using an adequate buffer. What
*could* be an issue is the effects of jitter on data recovery, against which
reading of the audio as a datastream and putting it somewhere else for a
while is utterly irrelevant.

Has he published the details of how he did any level-matched blind
comparisons and how the stats of the results came out? Ditto for various
other details? Has he attempted to give a useful definition to "most all
digital players" beyond "those that would suit his assertion"? What fraction
of all the CD players in use has he tried, etc?

He thinks that this could be eliminated by taking the audio off the CD
as a datastream and putting that onto a hard drive and replaying that
via a good sound card. This according to Jamie would then get rid of the
jitter and thus make the CD audibly better..

What comparision measurements are there for the jitter from the soundcards
he uses, done so as they can be compared with published jitter measurements
on CD players? Has he supplied any data on this to support his claims?

Just interesting to see what the contents of uk.rec.audio think of that..

Up to them... although I would not normally call a collection of people,
'contents'. In uk.rec.audio 'discontents' might be more accurate. ;-


Slainte,

Jim

Did you choose it because it said "Audiophile" on the box? :p

My apologies for Tony's actions, and for dumping this thread mid-way
into another group (I cross-posted a response without noticing the
first time).
Tony is something of a semi-troll, and a person with limited intellect
imho.
I think he was trying to impress some of his pals from the Digital TV
groups (they all pick on me because I'm gay) by cross-posting -
presumably in the hope that my comments in this thread would attract a
barrage of ridicule from the members of uk.rec.audio .
