Hi
I use Eac, feurio , and nero to burn music

At which speed should I burn audio ? to make a good copy?

sound better a burned cd writed at 2x then 24x ?


and is there a burning software that make the copied cd sounds better?

CDR FAQ

You may like to have a read of the above. There are some good informations there.

My personal experience in IT has shown that 8X is a good mark for maximum compatibility. In an ideal world, faster would be fine. I have however seen several older CD drives and car players that don't like to read CDs burned at higher speeds. If you hold a CD up to the light you will notice a visible difference in the tracks laid down at 40X versus 8x.
Please note, most CD writers only write higher than 16x on the outer tracks. So in truth, a 48x burner does not burn the whole disc at 48x.
I also agree on Taiyo Yuden media. I have had no problems at all with it. I cannot say the same for several other brands, which were often rebranded CMC Magnetics ( crap in my opinion and according to reviews ) This includes Memorex by the way.
Sony media is widely available and quite good. It is typically rebranded Taiyo Yuden or Mitsui, which are both quite good.

The relation between burning speed and compatibility is merely an apparent one. What matters is the error level of the media at a given speed, and that will vary from burner to burner, too (and even from one firmware revision to another). The "the lower the speed, the fewer the errors" rule is no longer universal: I've seen (and have scans to prove it) some MCC media burn better at 24x than at 16x or 4x.
I will concede that unless you have a winning combo on your hands (e.g. a Plex + TY) it is prudent not to push beyond a certain limit when burning CD-DA, though.

A further complication is that the brand the disc is marketed under is more often than not misleading. I bought a spindle of 52x Maxells some four months ago, and they were Prodisc. A couple of weeks ago I picked up another one, and it was CMC. Same packaging and the discs look exactly the same.
I've seen all kinds of Sonys, too (mostly crap). And believe it or not, I still have a few Memorex-branded Taiyo Yudens lying around (though CMC is a lot easier to run into :). The only way to be sure of what you are getting is to go with a well-established product line like Maxell CD-R Pro (TY) or Verbatim DataLife Plus (MCC); or else to buy from a reputable place like Rima who sell genuine bulk TY.

Lastly, there is CD-R Freaks' media test results database, along with their excellent Media FAQ. The FAQ, btw, covers these issues in detail.

The bottom line with optical media is: YMMV =). Test and see what results you get on
your system with a particular media at a particular speed. For CD-DA burning, I wouldn't go over 24x.

P.S. I never observed the purported difference in tracks layout between CD-Rs burned at different speed. Perhaps I don't know what to look for? Hmm, some scans would be nice to see, ddrawley :>

P.S.2. (free grammar lecture :)

Please note that in common usage information has no plural.
The school is in - yay!

Give yourself a chance.
Burn two discs about %50 full.
One on 8X.
One on 24X.
Turn the disc over and rotate left to right in sunlight so you can see the 'rainbow'
You will see a distinct difference.
At the risk of flames, the pits seem to be etched deeper. I am easily able to see the difference.
Anyone want to help me ABX

thanks mate

I'll take you at your word, dd.
Now how is deeper better?

The basic nature of the cdrom is the key.

** Warning, simplistic explanation follows - critique is not needed.

Pits are cut by the laser into a cd-rw to write the '1' or '0' of data.
The laser bounces light off these pits when reading a disc.
If the naked eye can see the difference, so can the laser.
Marginal or slightly out of spec readers are then more able to pick up the cleaner recording.
I have had great success with a large PC rollout this way. Older CDROMs that would not read cds burned at 16x or greater did fine whith 4x or 8x burns.

I found that 16x or 20x are the sweet spots with my Plex Premium and Taiyo Yuden media ... the BLER of the recorded discs will be at the lowest possible level.

If you want to find out about writing quality, you can visit CDR-Info ... with every later CDRW/DVDRW review, they do post Jitter/BLER measurements with different media at different writing speeds ...

Simplistic, indeed!
It doesn't take into account Red Book specifications that mandate that the difference between pits and lands (also known as beta) not be out of a certain range (0-0.08, to be exact).

As for the "slower is better", there are more factors at work here than just burning speed. Have a look at Media FAQ at CD-R Freaks for pointers.

And 24x for my Premium and Verbatim DLP 52x. Still have to sort out and post those scans done more than a week ago - dang! Wouldn't it be nice to have 36hrs in a day?

@Never_Again
I am sure we are all impressed by your superior knowledge.
I am not sure how that will help non technical users.
Please note I did not say slower is better. Prior research shows some drives produce more errors and problems at 2x or 1x.
The 8x is a basic, simple, fairly certain approach.
Users who have the ability to determine the BLER of the recorded discs they use will of course not need this basic guideline.

Edit:

Please note the heading the person used to start the thread:

hei i can't use k's cd/dvd probe because i haven't a liteon
i have a plex , sony writes and a asus reader

what can i use to make some test ?
