Hi,

I'm curious what people think is the best speed to burn an audio cd. Things I want to consider here are jitter (I don't really believe in it as such but theres no harm in taking it into consideration i guess), c1/c2 errors and readability in players.

I'm looking for low jitter, low c1 errors and high readability. I know I can find this out through trial and error but considering the number of people who use Mitsui & TY discs and also use Lite-On CDR's and the number of people who consider quality important in this forum, I thought it would be worth asking.

Cheers,

yup...


a good burner at low speed...

min: 2x - max 12x... i would go for 6x for audio
with todays burners...

i use 4x... and never a bad burn...

8x speed is fast and good. That's IMO the best speed, because lowering the speed more doesn't exactly mean less BLER or C1.

Is the decision to burn at these speeds based on any kind of evidence from testing or because you feel like its a good thing? Have you had problems that have been solved by burning at such a low speed?

I'm no expert on this subject, but there are others on this board who are. I suggest a search may be of help to you. From what I have seen, the optimum burn speed seems to vary according to manufacturer and model of rewriter, the media itself being another factor.

yup...


it`s based uppon simple logic.. and experience...

as Syleth say. 8x.. so you can fearly say
it mostly depends on overall speed..
divided into....... type of media.. and qualety of
the burner (as of capabilities)

I will add my experience here. I hope someone will comment too because there is very little consistency of opinion for this.

When I first got my burner, I was asked by relatives to burn various compilation cds for them.

What I found with my Sony crx-140e was that if I burned at any higher speed than 2X with any media that was not the light gold phenylcyanine dye, that there would be playback problems with my family's hardware.

Often the devices would have garbled playback, or not even register that a valid cd had been inserted.

Blue or green dye disks were useless, and also present problems with some of the svcds I make.

The firmware has always been the latest, and computer drives never have any trouble with the cd's I burn, no matter what speed.

I hunted around for a tool that would allow me to tweak the laser power manually but finally gave up.

I had a particularly bad run of coasters last summer during a heatwave where the temp of my house was in the mid nineties. The temp inside my box was also hot presumably.

Well, i've had mixed experiences with my Lite-on.

I did some tests at different speeds and the best overall was 24X on quality discs. and 8X on crappy media (CMC)
16X and lower yielded a bigger C1 error-average with my burner on TY.
32X had more errors on the low quality medium but the same error rate as 24X on TY.

But don't take for grounded what I say and do some extensive tests because ev'ry burner, media, and the combination of both yields different results.

My burner is a LiteOn LTR-32123S using the latest (XS0Z) firmware. I used both CMC (Imation) and TY (FujiFilm) 48X media.

CDs I've burnt (all successful ) are at 8x with Yamaha 8424S SCSI.

Media was:
Samsung 24x 700Mb 80 Min (Manufactured by Prodisc, phthalocyanine, silver reflective)
Hi-Space Carbon CD 700Mb 80 Min (MPO, phthalocyanine, silver reflective + UV protection)

I have a 12x burner but I always burn audio cds at 8x. The main reason is that some cd players I have encountered have trouble reading cd's that I have burned at 12x. When burned at 8x they play fine on all the cd players i have tried......

An article I read on this topic: (I think I originally found it on a thread at HA)

http://www.emedialive.com/EM2000/starrett5.html

Summery: Modern drives burn fine at highest speeds, some are actually worse at lower speeds. All easily exceed spec.

Being worse at lower speeds is due to the media being made for higher speeds isnt it, rather than the drive not being good?

I think most recent burners (48x/52x) exceed recommended jitter levels don't they?
