Peculiar AcurateRip result

tourrilhes · 02-14-2008, 12:10 AM

Hi,

I wanted to share with you guys a peculiar result I had with AccurateRip. First, let me tell you that I love AccurateRip and my ripping would be more miserable without it...

A few words about the CD. I ordered it a few days ago at Amazon US (Valentine present for my wife). It's brand new, pristine. It did not even went into our stereo yet.

So, let's rip it... I'll give you the raw data and will try to refrain from making too many comments. I'll split the 'story' into multiple posts to avoid hitting limits...

Code:

Hi again, episode 2...

I know that my Lite-On is not the best ripper, so let's see what my Samsung think about it. It's in the exact same computer.

Hi again, episode 3 (last one)

Then, I remembered that I ripped the CD at work. I've got an old HP DVD 400i, which is a low quality BenQ clone. So, I fetched the results I got at work.

Ok, this one also get a confidence of 4.

One last thing : I have not yet submitted any AccurateRip result (unless EAC did that behind my back) and you have all the rips I did of that CD. In other words, the results in the database are not mine.

I'm waiting for your comments...

Hi,

I forgot to add that I also did a 'test' (technically not a rip) with the PX-230A. This is the result.

Pretty much like the other PX-230A result.

There, you have it all...

Jean

*Spoon* · 02-14-2008, 03:24 AM

I would say that:

The 230A is 100% correct, the other 2 drives which give an accurate result (4) are perhaps not correct (I have seen mentioned CDs with manufacturing defects, it could be if that disc, or others from the same batch are ripped on certain drive chipsets then the result is as you have seen, others have had problems also with the same cd).

Spoon - now that's an unexpected result - one would think an Accurate (4) rating would assure you that the rip is good.

Perhaps this is one of those rare last tracks where the audio data continues up to the end of track boundary, and some drives are better than others at assuring that they are sample accurate right at that border (perhaps related to the offset and lead-out reading capabilities?)?

*Spoon* · 02-14-2008, 08:25 AM

AccurateRip is not effected by drive offsets and overreading.

When there have been about 20 million tracks ripped with AccurateRip you will come across strange happenings, this is one of them. All we can be sure is that 2 different drives give 2 different results, and different people with different discs have had both results.

It would be worth (if you want to investigate it) try dBpoweramp R12 to rip and enable c2 error pointers on the Lite-on and Plextor (as they both support) this gives an extra layer of confidence, it would be interesting to see if the results match the ones above.

I personally believe this is the case, but you must admit that your hypothesis is only based on circumstantial evidence (i.e. your own experience of the PX-230A) and nothing from the data itself can lead to this conclusion.

Yep, I believe there is a pressing defect. Note that, if there is a pressing defect, in theory none of the rip is perfect (you can't be assured to reconstruct the data before pressing), or you could say all rip are equally valid interpretation of the bogus data.

Yep. Interesting, isn't it ?

I've had many of this discrepancies between my drive. If the CD is not in AR, I rip it with the Lite-On or Samsung, and verify with the PX-230A. Because the PX-230A has a bigger offset, quite often they differ on the last sample of the last track.

But, this is not the case here. I've read on this forum that the CRC calculation in AccurateRip discard the last sample of the last track precisely to avoid this issue. And I've also check the difference between the tracks, and they occur 2/3 of the way in the track (if I remember correctly - sorry I'm at work).

I can confirm this is the case in my setup, I've seen EAC CRCs mismatching due to offset differences, but the AccurateRip CRC was always matching.

I'm sorry, but I disagree. We are not talking 20 million tracks, we are talking 14 rips of this CD. And, I'm note sure if people are as paranoid as I am, it seems that people are generally happy with a straight AccurateRip match, and most people don't have the diversity of drives to be able to test that, so maybe the error is more prevalent that this one present instance.

By the way, maybe we could revisit this thread :
http://www.hydrogenaudio.org/forums/...howtopic=60617

By weird coincidence, it's also a Lite-On... Same model as mine, but in SATA.

I'm sorry, but I spent enough time to get setup and validate my EAC workflow, I don't really see what dBpoweramp would give me in this instance. Note that C2 was enabled on the Lite-On (and the Samsung). I've just realised that the PX-230A was in burst mode, and that was an error on my part (but does not change the overall conclusion).

Note that the CD will be quickly in the hands of my wife, and I can't guarantee it will be pristine after that, especially with our kids. That's actually the main reason why I'm ripping my CDs. So, it may take a bit of time before I can do another rip.

Thanks a lot for the interesting discussion, and have fun...

Jean

EliC · 02-14-2008, 01:58 PM

I think he is just suggesting a quick rip in dBpoweramp, no reason to redo your whole workflow. C2 support is better in dMC then EAC so it would be interesting to see if there is any difference in results.

*Spoon* · 02-14-2008, 03:24 PM

> hypothesis is only based on circumstantial evidence (i.e. your own experience of

That and the confidence was 10, which was closer to the 14 of the other tracks. It seems there is a simple split, for the last track some drives (10 submissions agree), other drives (4 agree).

>I'm sorry, but I spent enough time to get setup and validate my EAC workflow

My intention was not for you to change from EAC, just doing my part as elimination of issues, if you try another program on those drives and get the same results then it eliminates EAC as a possible cause of this discrepancy (if you had used dBpoweramp I would ask you to try EAC).

I must apologise for my previous answer. I know realise that using dBpoweramp would add interesting information to this discussion. Which specific version would you want me to try ? I see that I should be able to get R12.4 as a free trial.

Thanks to Greynol in the EAC forum for taking the time to open my eyes on the issue :

As I said earlier, I may have a bit of trouble getting my hands on the CD in the next few days.

Have fun...

bhoar · 02-14-2008, 07:29 PM

Spoon - in addition, as these sorts of issues crop up and evidence points to particular drives not handling these special cases properly, perhaps results from certain drive/firmware combinations should be quietly blacklisted?

I think we should blacklist all drives except for the Plextor PX-230A.

I've seen undetected errors with my Lite-On and my Samsung, so we should ban all Mediatek based drives, which means all Lite-On/Samsung/ASUS. I've seen this type of errors with my old BenQ and my old LG, so we should ban all BenQ (except the PX-230A) and all LG. Pioneer don't report C2, so we should ban that as well. What's left ?

Seriously, I think the situation is not as bad as it looks. By looking at the AR log, it's obvious when this happens. Also, in 99% of cases, my Lite-On gives proper results. You want as many tracks as possible in the AR database. And I think we may be able to narrow down when this happens.

Have fun...

Jean

tourrilhes · 02-15-2008, 01:12 AM

Hi again,

I managed to get dBpoweramp installed and configured. Note that I disabled FUA as I read somewhere that the the Lite-On did not work with FUA.

I did 11 rips before a set of EAC rips and 2 after. That's a huge set of logs, so I'll pick a few...

Very first rip.

Ok, we can't always get a secure rip but at least we know there is an error.

All the other rips alternate between those 3 cases :

I had :
no-error, confidence 10 : 1,6,9,14
errors, confidence 10 : 2,5,7,8,10,11,12,13
errors, innacurate : 3,4

The CRC in rip 3 and 4 are differents. The number of errors is different, rip 5 has 9 re-rips. But at least, I did not see the dreaded "confidence 4".

Ok, I'll call that a success.

Ok, Confidence 10, I like it. So the Lite-On is capable of getting the right track with EAC after all.

Let's try another rip...

Ouch ! Confidence 4 again.

dBPowerAmp : 14 rips, never happens
EAC : 3 rips, happen twice.

Hmm... Interesting. I think I've now changed my mind about what's could be the cause here. You guys were definitely right to push me around ;-)

I guess we need to get Andre to comment on the subject.

Good night everybody...

Spoon Da Man Join Date: Apr 2002 Posts: 19,713	Re: Peculiar AcurateRip result AccurateRip is not effected by drive offsets and overreading. When there have been about 20 million tracks ripped with AccurateRip you will come across strange happenings, this is one of them. All we can be sure is that 2 different drives give 2 different results, and different people with different discs have had both results. It would be worth (if you want to investigate it) try dBpoweramp R12 to rip and enable c2 error pointers on the Lite-on and Plextor (as they both support) this gives an extra layer of confidence, it would be interesting to see if the results match the ones above. __________________ Spoon www.dbpoweramp.com

EliC dBpoweramp Guru Join Date: May 2004 Posts: 905	Re: Peculiar AcurateRip result I think he is just suggesting a quick rip in dBpoweramp, no reason to redo your whole workflow. C2 support is better in dMC then EAC so it would be interesting to see if there is any difference in results. __________________ dMC R14.x Requests and Suggestions PerfectMeta Discussion.........PerfectMeta Formatting........PerfectAlbumArt Re-Rip Difficult Tracks Across Multiple Drives Open DSP Architecture Request CTDB - Actually Repairs Bad Rips

Spoon Da Man Join Date: Apr 2002 Posts: 19,713	Re: Peculiar AcurateRip result > hypothesis is only based on circumstantial evidence (i.e. your own experience of > the PX-230A) and nothing from the data itself can lead to this conclusion. That and the confidence was 10, which was closer to the 14 of the other tracks. It seems there is a simple split, for the last track some drives (10 submissions agree), other drives (4 agree). >I'm sorry, but I spent enough time to get setup and validate my EAC workflow My intention was not for you to change from EAC, just doing my part as elimination of issues, if you try another program on those drives and get the same results then it eliminates EAC as a possible cause of this discrepancy (if you had used dBpoweramp I would ask you to try EAC). __________________ Spoon www.dbpoweramp.com
