Title: Drive or Software for burning Audio CD's at 8X or below?
Post by: Pipeline79 on 2017-08-18 13:35:47
Hi there,

I have a (Hi-Fi) CD player that is fussy about the quality of the audio CD's it will play without skipping, stalling etc.  Regular, purchased music CD's play fine, just burnt CD-R's.  The manual says they should be 8X or below. 

I've just bought an LG GE24NU40, because in the specs on the website it listed 4x, 8x and 16x, etc as supported write speeds for CD-Rs.  Now I've tried it and it seems just the same as any other drive (I've now ended up with three) in that around 14-16x is as slow as it goes even if I select 8x.  I've got some special CD-Rs that are designed for slow speed burning, but it's the same.

What does everybody else do?  Should I try looking for a really old external CD drive?  Find some special software (I can't find any)?
Is there any sites where you can tweak the firmware somehow?

I know I could just listen to the music from my computer but it doesn't sound as good, plus I don't want my computer on all the time whirring away when I'm listening to music.

The manual says they should be 8X or below.
A CD player should be able to play CDRs, no matter what speed burned with a modern drive.
Once Marantz had some drives that must been modified with a capacitor by their service and they played fine after.
If a manufacturer today directly suggests 8x burning in the manual because its drive can't handle CDR correctly he may make fun of you. They could do better.
What CD player is it with this manual?

A few years ago, I experienced playback issues on my Marantz CD-67, when I had burnt Audio CDs at 16x speed or above, but at 8x they all played back fine.

try

the process for making Audio CDs is pretty straight forward

if that fails to reduce your burner's writing speed

try

here's a guide for making Audio CDs with Imgburn

In the german online manual is no word about CDR or burn speed.
Maybe the drive starts to wear out.
I had good success with blue Crystal Azzo Verbatims with an old car radio having problems with cheap gold CDRs.

Thanks Maggi.

Unfortunately I am using imgburn already, with that method.  The problem is that even if I select 8x it still writes at a higher speed.

I think it must require something beyond that.  Was hoping someone had a drive that they knew would do this.

It's in the manual I got with it.  :D  Page 8, OK?

Maybe it is wearing out, maybe not.  Like I said 'purchased' CD's play fine.  The higher quality ones are better, yes - it's just irritating that you can't get your drive to spin any slower now.

I'd just like to see if it makes a difference before paying to have it serviced.

Nonetheless i find the 8x recommendation not a good sign for a drives performance.

Sorry, Wombat ... that "R" slipped on my part, but in your linked manual (http://rega-audio.de/cd/apollo/downloads/Rega_Apollo_Bedienungsanleitung.pdf), they have the same sentence on page 5.

Maybe they try to compensate for cheap / low quality burners in order to preventing too much support emergence ?

I've tried CDBurnerXP, you can choose a lower speed, but it doesn't give you a running report on the speed achieved.
I burned one at 8x and one 4x, they both took nearly exactly 4 minutes from start to finish, which makes me think they're both probably just burning at 16x or whatever.

Doesn't make me wonder at all anymore ... besides that "burned-too-fast-issue", my Marantz CD-67 always had problems reading the start of track #1 of my original Delicate Sound of Thunder Disc 1, but my cheapo DVD player read it just fine.

Obviously, those "higher end" components have way better DA circuits, but since I've hooked it all up digitally, I couldn't care less.
Nowadays, I use my ~50 Euro LG BluRay player for playing back all optical medias and never had a single hickup.

4x, 8x for CD-R?

As for the CD player, I think it's well known that the more expensive a CD player is it probably makes it less stable at playing dodgy disks.
Not arguing this is justified, but it's what i've heard.  Eg, CD walkman's are better, because they're designed for the bumps of course as well.

I can only comment this from a technological manufacturing perspective: it's difficult to tune for lower and higher speeds.

In fact most CD recorders are tuned for higher speeds, and the low speed functionality is kinda "slapped on" to meet consumer requirements of "lower is better" while in fact in practice, this is usually the opposite.

Why that Rega player would hint at "slower is better" makes no sense, and the burn quality vs. burn speed is entirely up to the recording hardware. Unless Rega keeps a list of manufacturers and "best burn speed" and other coefficients and variables for each of those, that information is really mostly just audiophoolery. The later Samsung 48X recorders were famous for having their best recording results at 48x-speeds and degraded below that. The BLER (Block error rate) got higher when recording at lower speeds).
I know this sounds counter intuitive, but if you research the entirety of the 00's decade you'd usually find results like that.

Usually recorders (and this is true for all contemporary optical media recorders, CD, DVD, BD, and for all I know probably HD-DVD, too) have one optimized recording speed, and the manual will usually state that. They used to market them as "32x, 48x, 52x" sometimes to sound more dramatic, I'd presume. To get best results, you'd simply want to record at that speed, and that's it. Computer journals and magazines used to do test and reviews of these recorders, some of them published BLER vs. recording speed. Not sure if they still do it, I haven't touched optical recording for at least 10 years.

As I understand it, it is often quite impossible for mid-ranged CD recorders to even achieve speeds lower than 8x when they're manufactured for 48x speeds, it's usually down to it being a physical hardware issue, of the motors not being able to spin smoothly at such low speeds, as well as achieve decent angular velocity synchronity. For playback, the CDs are read at higher speeds and buffered.

To be fair, I'd almost want a CD player, that rips the CD EAC-style into a buffer at high speed and then plays from memory. Just put 1GB of fast RAM into one of them, and there you go.

Also, Rega doesn't mess around: http://www.rega.co.uk/valve-isis.html, tubes, red dot-matrix LED displays, it ticks all the boxes of 70's Hi-Fi style. That's one serious CD-player if I've ever seen one. Also, this: http://www.rega.co.uk/mains-power-lead.html

I might be confused about the problem, but the audio CD player should be playing at 1X and it shouldn't care about the speed rating of the disc or the speed at which it was actually burned.

There was a time when you could get a "better burn" at slower speeds.   I don't know if that's still true or if burners have improved.    But with newer-faster burners, I assume the slowest speed works as well as the slowest-speed on an older, slower, burner.    It's been awhile since I've bad any "burning problems" and no longer pay much attention to the speed.

You may have a bad batch of blank discs.   You might try a different brand, or just a different batch.   

Or you may be right that the CD player is wearing-out.  The CD player in my car deteriorated and started having trouble with some burned discs, then it got to the point where most burned CDs wouldn't play, but commercial CDs were (mostly) fine.   I got it repaired and it was OK.   (Now I have an adapter for it, and I play my iPod in the car.)

If memory serves most drives shift to Z-CLV when burning at 16x where 8x is the max CLV writing method. Personally I always burn audio CD's at 8x CLV for other people because I don't know what kind of player(s) they have. It doesn't always work out either, the last batch of CD's I made had about a 10% failure to play in other persons' players and that might be due to the brand of blank CD-R I used (and that the blank CD-R's were purchased years ago if it matters).

Whether it plays at 1x or at higher speeds using buffering, should make no difference. Unless the recording speed is recorded into subcode of the lead-in, which normally isn't the case, the player has no way of knowing at what speed the disc has been recorded.

I haven't seen a CD player for 20 years or so, that would not use buffering.

There was a time when you could get a "better burn" at slower speeds.  I don't know if that's still true or if burners have improved.    But with newer-faster burners, I assume the slowest speed works as well as the slowest-speed on an older, slower, burner. It's been awhile since I've bad any "burning problems" and no longer pay much attention to the speed.
Slower burns made more sense with slower hardware in general. Buffering was complicated and there was a problem of "buffer underrun" should it take too long to send data to the recorder. These days (anything post ca. 2005) it's like I said in my previous post, where the hardware actually has a harder time recording on slower speeds than on higher speeds.

You may have a bad batch of blank discs.  You might try a different brand, or just a different batch.   
Also, some players don't like all of the recordable CD formulations. It seems some older players don't like the Azo dye.

Or you may be right that the CD player is wearing-out.  The CD player in my car deteriorated and started having trouble with some burned discs, then it got to the point where most burned CDs wouldn't play, but commercial CDs were (mostly) fine.  I got it repaired and it was OK.  (Now I have an adapter for it, and I play my iPod in the car.)
Them wearing out is usually down to dirt and dust. I've brought several of these back to life simply by cleaning them and especially removing grime with isopropanol from the lens assembly which is basically just floating inside a magnetic field.
Another common failure mode, is the lithium grease turning to gunk.

A manufactured CD has a physical pits, i.e. indentations in the aluminium are physical indentations. Recorded discs have a dye which basically becomes darker in places where the recording laser has been fired on, which makes it less reflective. So a recorded CD is always only an approximation of a pressed CD. The reason why older players seem to break down, is because they rely more and more on the forward error correction. While the SNR of pressed CDs and a dirty lens is usually enough with the error correction to produce a decent result, while it's usually too little to work with. When the error correction is unable to reconstruct the bits, the frame will get rejected, making a CD "skip".

Having said that, recorded CDs - some dye formulations at least - break down over time. Once they get so far gone the error correction cannot reconstruct them, they're unreadable.

I haven't used optical media beyond DVDs, so I don't know about BD dye formulations, how they hold up in players, etc.

I can't fin any mircometrical measurements of the laser engraving deepness in the laquer vs engraving speeds.
The lower the speed is, the higher is the light power transmitted to the laquer surface, the engraving contours are better defined and deeper... resulting in less reading errors.

OK, that's a lot to take in.

I think it's never been very good at playing CD-r's.  I have tried cleaning discs from time to time, but I've not noticed any improvement.  Could be it was slightly faulty from when I bought it, I don't know.  I've spoken to the dealer and asked him to ask Rega what they say about this, so I can post back if I get a reply on that.
I've bought an old Teac IDE drive that writes CD's only that has the 4x and 8x CLV modes for less than £10, so if that improves things I'll post on that too.

If I had a CD player that wouldn't play some CDs, I'd pitch it because good CD and DVD players that are perfectly good are so cheap and so readily available (and also so inherently inferior and useless).

I'd also be concerned that I'd be tolerating audible defects out of sentimentality for the old girl.

Your claim that there is this magic CD Rega player that uniquely sounds good is unbelievable without better evidence. You may perceive that, but it takes more than an unsubstantiated exceptional claim based on a sighted evaluation to be acceptable around here. You know, around here we don't mess with kid stuff, right?

Frankly, its been years since I've actually listened to a CD played on a CD or DVD player.

I have a number of optical disc players stashed, but only one of them, the Panasonic BD player is actually hooked up and will power up if you try to turn it on. I only use it to play BD-videos.  Its only connection to the rest of the system is HDMI.

I rip every CD I obtain and play the resulting files on one of my digital audio players.

I don't know if you realize that CD players are the worst way to play CDs because they don't do retries if they encounter read errors like a proper ripping program does, but instead just try to cover the mess up?

You might try looking for a Plextor drive that supports PowerRec or VariRec

"Plextor's new DVD writer also features their VariRec, or Variable Recording, technology. This technology not only improves the quality of recorded audio and data by minimizing jitter and reducing error rates, it also allows the user to manually adjust the drive's laser power." ~ http://www.cdrlabs.com/reviews/plextor-px-716a-16x-dvdrw/features.html

With all due respect, error correction aside, is it possible some CD players may sound "better" because they output higher signal levels and can drive systems to louder volumes, therefore the perceived quality may seem greater?

I think I can see where you are headed.

IME many audiophiles are so shallow in their understanding of audio system setup and operation that they make those kinds of mistakes.

Relevant facts may include the fact that a typical component CD player's voltage output at digital FS is on the order of 2 or 2.5 volts RMS, while most consumer PC audio interfaces output about 1 volt under similar conditions.   This is a 6 or 8 dB difference.

Most component integrated amps and preamps can be driven to full output with signals as low as 0.2 volts or 200 millivolts.

If one is clever or brave enough to simply advance the volume control a little further clockwise, the amp can be driven to full rated output and beyond by even the lesser 1 volt output of the PC. 

Thus, claims of a sonically precarious piece of gear sounding better than one that actually operates in a more ideal manner may be heard. 

ABX testing includes level matching, and are not so easily deceived.  Of course, to match levels one might have to spend a few dollars on a DVM, and perhaps more significantly learn how to operate it and interpret its evidence. 

In the face of massive audiophile peer pressure to not be a "Meter Reader", logic and reason are set aside.

I think the smart thing would be to buy a new CD player (or a DVD or Blu-Ray Player).     You can buy an inexpensive one and continue to use the old one with commercial CDs if you wish.    And, of course, the new cheaper one will sound better with those hard-to-play burned CDs, since (hopefully) they won't skip.   And, it will probably sound identical to your old one with "good discs".  

If you need analog outputs, make sure any new player you buy has them.   My (inexpensive) Blu-Ray player can play CDs and DVDs, but it doesn't have analog audio outputs.

@DVDdoug
That is definitely true.

I get hung-up on the issue that players have playback issues at all. "Is it the burn speed? The type of CD-R? A combination of both?"

When I send burned audio discs to others and get a report of problem with playback I'm thinking more of how I could do something different.

I have suggested to people with playback issues to try another player or use their computer. For me, the questions remain. I've tried 4x as well. At one point I thought certain players would not like burned CD-R's over "pressed" ones... right until those same finicky players did recognize burned CD-R's instead of giving a tray load error.

Well, I've first-hand witnessed the problems CD players have with burned disks at Croatian radio. They wanted to use copied disks to preserve originals, and to make compilations for broadcast. This was some 15 years ago, now they went full digital - but then, they played music from CDs, even tapes and vinyls sometimes.
Anyway, the most used player was TASCAM 401 (I think, I've checked the pictures and it looks like that one) and while it was playing originals well, it had much trouble with CDRs. We tried different combinations of media and burning speed and finally got the combination right - they worked as they should ONLY with Taiyo Yuden or Mitsubishi Chemical Corporation disks (you'll remember them from early days of testing CDRs, they were expensive but good and long lasting) and written at 4x. People who were making these CDRs already had Plextor drives as they were among the best in these days. Later on, as Plextors broke down, other drives were tested and found OK, as long as they could record at 4x speed on that media.

So, I would suggest OP to drop that CD player :) too much hasle. Transport is crap if it can't read CD-R in 2017.

I don't believe it works like this. The laser's intensity is modulated to transfer a precise amount of energy into the dye. At lower burning speeds, the laser will be less bright. The changes to the dye will be slower. As polemon already pointed out, this may actually produce worse overall results.

Lol.  Well, for what it's worth I've just stuck a £10 20-year-old CD-R drive in my computer and burned one 'Higher Quality' CD and one cheap TraxData CD.  Drive burns at 4X max.  Both play perfectly in my bullshit too expensive Audiophool CD player.
Make of that what you will.

I didn't say that all!  I only said I prefer listening to the CD's because the sound is better coming from the CD player which is closer to my Amp - I didn't put it down to any magic properties of the Rega brand.
In fact I only mentioned the model because I was asked.
All I actually wanted was help with how to find a way of burning the discs slower.

In the early days I had Plextor drives. These drives were able to burn CD's at low speeds and had many options you could set that enhanced the quality. Later drives were relabeled generic drives unfortunately. You could try to find such a drive. You could be needing an IDE port though.

I can't fin any mircometrical measurements of the laser engraving deepness in the laquer vs engraving speeds.
The lower the speed is, the higher is the light power transmitted to the laquer surface, the engraving contours are better defined and deeper... resulting in less reading errors.
I don't believe it works like this. The laser's intensity is modulated to transfer a precise amount of energy into the dye. At lower burning speeds, the laser will be less bright. The changes to the dye will be slower. As polemon already pointed out, this may actually produce worse overall results.

it is depending of too much factors i prefer measurements than speculations.

Also, some players don't like all of the recordable CD formulations. It seems some older players don't like the Azo dye.

This. Not all CD-Rs are the same. Find a site that lists what actual brand/dye etc are used in the CD-Rs as it does make a difference, even though it shouldn't really.

Hi there,

I have a (Hi-Fi) CD player that is fussy about the quality of the audio CD's it will play without skipping, stalling etc.  Regular, purchased music CD's play fine, just burnt CD-R's.  The manual says they should be 8X or below. 

I've just bought an LG GE24NU40, because in the specs on the website it listed 4x, 8x and 16x, etc as supported write speeds for CD-Rs.  Now I've tried it and it seems just the same as any other drive (I've now ended up with three) in that around 14-16x is as slow as it goes even if I select 8x.  I've got some special CD-Rs that are designed for slow speed burning, but it's the same.

What does everybody else do?  Should I try looking for a really old external CD drive?  Find some special software (I can't find any)?
Is there any sites where you can tweak the firmware somehow?

I know I could just listen to the music from my computer but it doesn't sound as good, plus I don't want my computer on all the time whirring away when I'm listening to music.




Hello  i did find a cd burner it can write to cd-r  from 4x-40x it is a Pioneer BDR-209DBK. From amazon
I purchased it and it does write at 4x.
