Peculiar AcurateRip result

Re: Peculiar AcurateRip result

Hi Jean, Spoon, Brendan, Eli and whoever else I know from Hydrogenaudio and/or Digital-Inn.

This situation with EAC is pretty interesting. I'm curious to know what happens when you disable C2 pointers in EAC. When this is done, EAC will ask the drive to access different points within a track. It might also be worthwhile to try the rip in burst mode. Maybe one of these changes will make a difference(?).

Quick explanation (hopefully):
Without C2 pointers, EAC reads 27 sectors at a time until 2MB is read and then goes back and does it again. The next pair of 2MB sets will begin with the last 2 sectors of the previous pair for synchronization purposes. With C2 pointers, EAC reads 24 sectors at a time until 2MB is read and then moves on to the next set of 2MB beginning with the last 2 sectors (again for synchronization purposes). If cache flushing is enabled, EAC will read another 2MB prior to moving on to the next 2MB in order to make sure the 2 sectors used for synchronization are read from the disc (with or without the use of C2 pointers).

My limited understanding of dBpoweramp is that all passes (including ultra-secure) are done in burst mode and that no additional synchronization is used.

Lastly, I am concerned that dBpa is telling you that bad rips are secure when using C2 pointers with your Lite-On. This implies that you're getting consistent errors which are not being dropped by C2 pointers. It should not be behaving this way. I was also going to add that it should be safe to increase the maximum number of re-reads when using C2 pointers, but now have reservations in light this issue.

>Lastly, I am concerned that dBpa is telling you that bad rips are secure when using C2 pointers with your Lite-On.

We are seeing a CD with errors right at the end of the track, the occasion when dBpoweramp failed to rip the track:

Track 17: Ripped LBA 322181 to 340190 (4:00) in 0:46. Filename: F:\Music-dBamp\Simple Minds\Simple Minds - The Best of Simple Minds Disc 1 - 17 - I Travel.flac
AccurateRip: Inaccurate (confidence 4) Secure (Warning) [Pass 1, Ultra 1 to 3, Re-Rip 5 Frames]
CRC32: A99AA633
Re-rip Frame: 336063 (00:03:05.093) matched 10 / 14
Re-rip Frame: 336174 (00:03:06.573) matched 10 / 14
Re-rip Frame: 336684 (00:03:13.373) matched 10 / 14
Re-rip Frame: 336685 (00:03:13.386) matched 10 / 14
Re-rip Frame: 336795 (00:03:14.853) matched 10 / 14

Yes the error got past c2 pointer, and was consistant on 5 passes! perhaps c3 is not great on the Lite-on. Those frames which were re-ripped, they might not have been the ones that had the error.

For you to debug the EAC issue, if you can supply 2 wave files to Andre, one with the confidence 10 the other confidence 4, looking at the data he might know what is happening. This is an issue that needs looking into (as 4 other people had the same issue, and must be using EAC).

Re: Peculiar AcurateRip result

Hmm...is the issue that the bad (but matching) rips are being submitted from EAC, not dbpa?

Re: Peculiar AcurateRip result

Yes, but not always.

**Spoon** · 02-15-2008, 08:05 PM

Re: Peculiar AcurateRip result

To be fair to EAC (and if you have the inclanation), rip 6 times in dBpoweramp with the c2 off and check that it never show the confidence 4 on the liteon.

Re: Peculiar AcurateRip result

Hi all,

I've got some interesting new information. But let's start with a raw dump of data, as people may always find bits in there that I may have missed.

I decided to try a few rips at work. My work PC is different, single P4 instead of dual, different drives, different EAC version, same XP-SP2 though. I installed dBpowerAmp R12.4 on this box.

I plugged in my old HP cd16 (a LG GCE-8160B clone) that I was considering for ripping a while ago, before discovering that it was not good enough.

The other drive is the HP DVD 400c (a BenQ dw800a clone) that you have seen in action earlier.

I launched a first rip with the cd16 and dbpower amp and went for luch. When I came back from luch, the PC was dead. No BSOD, just black screen. After a reboot, I was able to get the following log :

Hi again,

Now, of course, we want to know how EAC compare on the same setup.

While I was setting up and configuring dBpoweramp, I did a rip with EAC on the cd16. The rip took around 1h30, including two cooling periods of 10min.

This drive is usually pretty fast, but is bad on scratches. I basically retried every single block on the last third of the song.

Let's move to the HP DVD 400c. Remember that I already ripped on that drive (it was the very first rip I did), and that I found confidence 4 back then. Let's try another rip.

Re: Peculiar AcurateRip result

Hi again,

I started scratching my head, and wondered what was the difference between EAC and dBpowerAmp. One of the biggies is that dBpowerAmp does its first rip in burst mode, whereas I configured EAC to use Secure mode.

What about EAC in burst mode ? Let's try on the HP DVD 400c.

Confidence 10 ! Interesting.

I did a total of 4 rips in burst mode with the HP DVD 400c (including the above), and all of them returned confidence 10. The fourth and last rip is below.

So, Geynol was (again) on something when he suggested me to try EAC without C2. The HP DVD 400c does not have C2 reporting (like all BenQ drives), so I can not try that here.

Also, remember that my PX-230A was in burst mode. It was an configuration error on my part, but without it I would probably would have missed this problem entirely. Probably it should stay in burst mode.

Finally, we have still not yet determined which version of the track is the "most correct" one, but I'll work on that soon.

Have fun...

I expect that you have full access to the database. Would it be possible for you to verify what were the setup of the 10 and the 4 people ? What software they where using, which settings and which drives ? I know that you at least have info about the drives in the database.

Have fun...

Yes, but unlike that user, you're experiencing consistent results with dBpoweramp.

I want to reiterate that all passes performed by dBpa are burst passes and you get the same result when ripping with EAC in burst mode. Busting out this thread can lead to some serious consternation, but let me just offer this post:

I fully agree, but IMHO we don't have sufficient info to know if the two issues are related or not.

My point is that we should look in the AR database to see what kind of information we can get about the 10 and the 4 matching rips to see if we can confirm or infirm our current hypothesis. I would expect this info to be very interesting, as thhose other rips introduce more diversity.

We may want to make a call for testers on Hydrogenaudio to try to enlarge the test base. Could we track the authors of the rips in the database ? We don't have the source code to inspect, so the only thing we can do is to treat it as a black box and make more elaborate and diverse tests.

Yes. I don't fully understand what different about burst mode and secure mode in EAC, what I know is that in all my drives, burst mode is 2 or 3 times faster than secure, even on drives with no cache and C2 pointers. So, I expect something is different. The code path in EAC is different, and the code path in the drive firmware *may* be different, but I don't have enough knowledge here.

When I'm back home, I'll try burst and no C2 on the Lite-On. I'll try secure with the PX-230A. I don't know what to try on the Samsung.

Once again, you totally lost me, but that was probably not for me.

Note that I believe the EAC sync errors are reported in the log (I would need to check that). I'll pay more attention to sync errors next time.

Thanks again...

Could not wait. With the HP DVD 400c in secure mode (once) and burst mode (once), I could not see any sync errors reported. I know I've seen sync errors in the past with EAC and other CDs.

I had forgotten another burst result, so at last count on HP DVD 400c :

Burst mode : 6 rips with confidence 10
Secure mode (+cache -c2) : 6 rips with confidence 4

Have fun...

Then it's best to treat them as separate issues, otherwise you're asking us to disprove a negative.

I wasn't very clear why I gave you the link. Sorry about that. It seems to me that EAC may be incorrectly shifting the data for a best fit during synchronization without reporting an error. I could easily be wrong though, and it wouldn't be the first time.

Regarding what you find in logs, EAC only reports sync and read errors in the Extracting Audio Data dialog window.

I've seen sync errors in the past, so my expectation was that if EAC is finding some sync error in this case it would report it.

Note that, thinking about it, I believe most of the sync errors were on the PX-230 in burst mode. I can not guarantee that I've seen sync errors in secure mode. I'll pay attention.

The last two rips I did on the HP DVD 400c, I explicitely checked the various window dialogs for sync errors, and found none.

Re: Peculiar AcurateRip result

Sync errors aren't reported in burst mode and I can see from your logs that EAC is not reporting errors so you would not see a sync or a read error.

My concern is that EAC may be shifting the data without telling you, though I have no way of knowing since I didn't author the program. It would be useful to compare the two versions though I concede that even if the two files differ by a shift somewhere within one of the tracks (resulting from repeated or omitted samples) it wouldn't mean that EAC is altering the data after getting it from the drive. It could simply be in the way EAC asks for data that causes the drive to give different results, whatever the differences are between the two versions.

It would be good to know the offset of your pressing relative to mine so that I could try burning a CD and test it with various drives to help rule out a consistent defect in the pressing in the event that I can also recreate the problem.
