Hi everyone,
I just got a new SONY CRX1950U external CD burner (40X12x48), with a USB 2.0 connection for my computer. My question concerns burning speed and audio/file reproduction. I did some searches, and I found no consensus (maybe because none exists) or new perspectives on the ‘latest generation’ of CD burners. Can WAV files, for backup purposes, be burned at high (16 or 32X or even higher) speed with these newer burnes without introducing deleterious “errors’ to the files themselves? Does buffer under-run technology have anything to do with that? And, can audio cd’s (CD-DA) be burned at relatively high speeds without adding any artifacts to the sound? Again, does the buffer under-run technology play any role here? Backing up at high speed would be nice!

Thanks,
T
 
My experience has been that if I want a "for sure" burn, to burn at about half the maximum speed of the burner. For a final "master" CDR, I usually don't go above 8X speed.

The kind of info you are looking for is going to be hard to find. There are just plainly too many manufactures out their making burners, and they each release a new model every 6 months to a year. All these burners would need to be extensively tested with ALL the different media's (CDR's brands), and that would just take a lot of someone's time to do. And for what? How would somebody get paid for doing such a test?

Be safe with stuff you care about. DATA disk's at half the max speed of the burner, AUDIO disk's possibly half of that again!

I agree with sonus...I burn audio CD's at about the halfway point of the burner...and sometimes even slower than that! I'd rather wait a few extra minutes than have a coaster...although not sure how some of the "burn proof" technology is.
 
Thanks for the guidelines Ed. And BTW, I have learned alot from you via your post's from the past...so thanks again!

Your welcome teainthesahara !

Basslord, when I first got my new Plextor CDRW, I tried out the burn proof protection stuff. I burned a full audio CD at 24X speed while I dialup up to the internet, surfed, opened MS Word and Excel, and even had Wavelab do some DSP to something. The burn never stopped, and the audio CD, while sounding a little bit "thin" from the fast burn, was able to play just fine on other players. That technology does work quite well. Basically, it just makes sure that any resources needed to burn the disk and prioritized for the burn. It makes all other app's and processes wait until resources are available to do so. I tried this test on about a half dozen burns trying all sorts of different processes, and never did it fail!

One thing to note is that after 16x burning speed, all burner's starts to do multiple writes by using "tricks" of the laser, so you should never go over that if you are trying to burn a pre-master (i.e. something you are sending to be mastered, etc) it's dodgy to say the least. You'd be surprised what the block error rate is for a comsumer level cd burner with audio disks... It's cheaper to build a CD player with good error correction than it is to build one that is %100. ;-)

Check this out...

Glenn Meadows and Bob Katz did these tests

They don't look to good, almost sad. 100 bad blocks up to 7000 for 45 minutes of audio, and those burners were running at 1 and 2x... !!!

If you're burning a pre-master to be sent out, I'd go 1x with no programs running in the background. ;-) Everything else will get fixed by someone's CD player, hopefully.

Sorry, but that's not right. If the burn never stopped you just have a well tuned computer. Read this excellent pdf file on how burnproof really works:

Well I'm at school now testing the burn proof idea. So far I've made 2 full CD's (doing the 3rd one right now) all without creating a coaster. Not really doing anything extensive with applications though...just running 3 windows of IE.
 
has Software been linked to the quality of CD's burned or is it strictly H/W?
 
HW is the first concern... I haven't noticed too much of a difference in software besides "ease of use" but even if you burn at high speeds and it works on your sterio system it may not work on a consumers systems...because the player is what provides most of the error correction on CDs . So if the consumer has a cheap player with poorly written error correction algorithems, the CD may not play at all...even if it works on your system.

Personally I burn at 1x :) ...so obviously I feel big orders should be manufactured


Also be aware of the term "max" in CDROM drives... 40x max does not run at 40x... it can average somewhere around 13x. "true speed" CDROMs are available but are hard to find...as they usually never go over 12x ...even though they are faster than 40x in some cases. I doubt they are even manufactured anymore. the main bonus in truespeed CDROMs is that they woudn't sit and rev-up to the max speed all the time :)

Interesting! I should check my info first. :) I do know that the same machine I use had another burner that didn't have burn proof technology, and that I couldn't really do much of anything when I burned with it. Any other process I did while burning worked just fine with the old burner, and worked fast. When I put the Plextor in, that changed. Other processes didn't work fast anymore. I guess I can see where the confusion is now. But, none the less, the burn proof works quite well. :D
