ive recently made some cdr's

that play back flawlessly on my computer

but when i play them in my dvd/cd player

they have dropouts and sometime's diginoise ?

:wtf:


is this because they were written at high speed ? 48 x


ive ripped them back to the hard drive and there are no errors ?

Quite possibly. See this in the CD-R faq.

It might also be that your CD player has trouble with playback on discs burned at high speed. I general I would burn a 2 speed when doing a straight copy out of iTunes or EAC or 1x when comgin out of a digital editing enviroment.

ive already burned 1000's at 24 x with no problem so there is no chance im going to 1x or 2x

so

maybe its just time for a new dvd/cdplayer

from same page !


Put simply, there's more to writing at high speed than just spinning faster. It's entirely possible that writing slowly to "high-speed" media will produce significantly worse results than writing to it quickly.

maybe ill just go back to 24x since there seemed to be no problem there

i guess ive solved my own problem

went back to 24 x

burned 4 cdr out to 79 min and

all play fine !


maybe a newer dvd/cd player could handle the high speed burns ?

When you rip the audio back to the hard drive, does the wav file have those skips in it? Or it is just a problem with the player reading the disc?

If the first option is true, then you've ruined the audio by burning too fast and using buffer underrun. If the second is true, then the CD player just has a hard time reading the discs. So, which is it?

very interesting topic, thanks to the OP for pointing this out.

personally, i use Feurio for all of my audio CD burning needs. it will not let you burn audio faster than 24x as i recall - or there's at least some message stating that potential problems occur if you burn faster than 24x for audio CDs. as has been implied above, it may not be that the WAV data written to the CDR is faulty, but that a normal CD player (i.e. not CD/DVDROM drive) may have problems playing back the burned disc. very interesting stuff, indeed.

I had exactly the same problem as Ninja, with one exception, being that I was burning at 12x (even though I can burn at 48x) and I always burn at this speed and have never had problems until now...so I went down to 4x and it is now fine.

I had the same problem...player didn't like it but the computer did etc.

What I don't get is how my computer can burn at 12x with no problems ever and only just now start to produce these discs that the player doesn't like? It seems odd to change.

maybe your player is beginning to wear out and needs to slow down a little in its old age in order to write properly. check your burned audio cdrs for crackling noises, that's what happened when my old burner died (RIP).

thanks Five. It could be that. Although I'd be bummed if it was - i've only had my burner (came with a new laptop) for 6 months or so. Probably burnt 350 or so cds in that time of course.
