foobar 0.9 vs EAC Secure rip

Reply #25 – 2005-09-26 16:47:15

i made a test with my 2 "special" Blind Guardian CDs...

the discs are from the album "Live", which was released in 2003 with a nasty copy-protection. EAC can read CD1 in secure mode, though it's very slow. CD2 is unreadable in secure mode. It would take 2 hours for EAC to extract it, so i gave up.

now, that foobar supports secure extration, i wanted to give it a try, to finally backup the second disk to wavpack. I used Secure and Unlimited.

My drive is a LG GSA-4120B, offset +667.

here are my results, i calulated them with MD5summer (http://www.md5summer.org):

39ec0f7973f81c32a66a6234766120f2 *Blind Guardian - Live CD2 - LG Sync 4.wav

foobar seems to extract correctly, as the MD5 is the same with secure mode on CD1.

on CD2, it seems as if i got a lucky try with sync 2 (EAC in synchronization mode).

an interesting deatail might be, that wavpack outputs following MD5s for the foobar extractions:

CD1: b97916c7c62c7abd052dd56fc1e4e591
CD2: d3af9b64a02916bbf0c049eac577f346

i don't know why wavpack displays the "wrong" MD5, after compressing and decoding, the files are the same.

Thanks for your input.

WavPack stores the MD5 of the raw audio data (i.e.: excluding the file header). Nothing to worry about.

One of my drives has 8MB of cache.. What can we do in that case? Is there any way to tell foobar my cache size?

Is there plans to have it output a log?
[{POST_SNAPBACK}][/a]
Possibly, but there are complications with doing that from architectural point of view. Unless writing info to console (interrupted by playback messages etc) as well as creating separate log for each ripped track is sufficient for you.
[a href="index.php?act=findpost&pid=329526"][{POST_SNAPBACK}][/a]

Separate log info for each track would actually make lots of sense, particularly when some tracks are re-ripped because of glitches. That is a good idea of yours.

Could the files be tagged with the log data, like "LOG=Ripped using foobar2000 0.9b\ Paranoid Secure... etc" metadata fields in APEv2 tags? This would have a side effect of eliminating .log files and make sure every ripped file always contains its own correct log.

For those of us who are used to log files, a playlist menu option for exportation of metadata to a log file could then be added, or simply scripted using [a href="http://www.hydrogenaudio.org/forums/index.php?showtopic=29229&st=0&p=259105&#]foobar's customizable "copy" command[/url]. This would leave foobar's architecture intact and provide the desired functionality.

I found a track (All Along the Watchtower, no less) that has recoverable errors.

EAC is content after one bar in secure mode.

Tomorrow I'll try it in my Plextor, to see if I can find what the MD5 should be, or at least what my Plextor thinks it should be. I may re-test with a cooler drive also.

Edit, or "tomorrow is now here": OK, here are a few results from the Plextor (I think I'll get some more), and also a 4th run on the LiteOn, on a cooler drive:

It's looking like Plextor thinks the correct MD5 is 4c2c1f7b330fb3979587c5c3be1b335a, which was not achieved once on the LiteOn...

I'm tempted to say the winner on the LiteOn is dfbd610f46c29bb2daa604f342766db8. This has been achieved in all four runs in foobar with unlimited paranoid, and EAC twice out of four. I actually did a "test" in EAC right at the beginning of the test. The test CRC matched that of eac-liteon.wav, the first test on EAC - so I could say that this was achieved 3/5 times in EAC.

All in all not very conclusive though.

I thought, if EAC reported the copy to be OK, that you had a secure rip. This is obviously not the case, and only goes to prove why Test & Copy is used.

I've had enough of inconclusive results. After I've done some more Plextor runs to try to get some sort of conclusion I think I'll quit the business.

Edit: Oh, also some listening tests on the questionable part.

Edit, or "now it's the next day": OK, here are the results for All Along the Watchtower on my Plextor:

Listening Test

Unsuccessful. According to bit-compare with the WAVEs tested there is between 57 and 128 different samples in the files. I've examined a couple in Audacity and cannot see any glitch, let alone hear it. Examination of two files in a HEX editor showed only 7 (non-successive) bytes differing.

foobar 0.9 vs EAC Secure rip

[span style='font-size:11pt;line-height:100%']Conclusions[/span]

Considering the limited testing and dubious results these conclusions should be taken with a pinch of salt (except 1). However, I feel, after the work I have put in, some conclusions are necessary - even if it is to spark discussion.

Don't lend your CDs to your brother while travelling Europe. I can only assume he's to blame for my scratched Cure and Jimi CDs.
No ripper is infallible. Even EAC returns differing results depending on the drive. File this one under "nothing in life is perfect".
foobar's ripper in standard and paranoid mode is on par with EAC's error correction. In fact, with the Jimi test on my LiteOn, the results from foobar with unlimited-secure and unlimited-paranoid attained a better success rate than EAC (3:4 over 3:5) - unlimited-paranoid achieved 1:1 (4/4). As both applications have got things right, and got things wrong, I find it difficult to state which one is the better. However foobar's inclusion of offset correction and a Test & Copy system is a definite improvement over 0.8.3, and should be commended.
Limiting the drive speed is not necessarily better. If my dodgy conclusion for the "correct" MD5 for the LiteOn is correct, the best results were achieved, on that drive, with unlimited-standard and unlimited-paranoid. Also, with the pristine CD on the dodgy Samsung drive, unlimited-disabled was more consistent than limited-disabled. It looks like there may be something to be said for testing whether your drive prefers it or not.
The Samsung SD-616E drive at work is unreliable. My Plextor PX-W5224A is better at reading discs in any situation than the LiteOn or Samsung.
I'm not cut out for formal tests. I don't have the patience.

Edit: I expect to continue to use EAC to rip my CDs, mainly as I'm comfortable with it. However, if I could not use EAC for some reason, I would be quite happy to use foobar's limited-standard or limited-paranoid mode with my Plextor - being paranoid I would probably use limited-paranoid. Actually, this may depend on the quality of the CD. Limited-standard would be fine for a newer CD.

I guess a speed test may also be worth doing, for those people who seem obsessed by doing everything as fast as possible. I find it difficult to say whether limited-standard or limited-paranoid would be faster or slower than EAC. I seem to remember even limited ripping on the Plextor being very quick.

NOTE1: I deem dfbd610f46c29bb2daa604f342766db8 to be the "correct" result for the LiteOn. Not only was it produced the most times, but also with the most trustworthy modes, these being EAC and foobar unlimited-paranoid/unlimited-standard.
NOTE2: f97ae89101d7d814b61905a811658de3 is a curious partner, and may actually be the "correct" result - which would really confuse matters.

NOTE1: The Plextor reports no errors on the CD.
NOTE2: The mismatched MD5 can only be put down to a glitch. I would always use at least standard security anyway. The fact that the Plextor MD5 and the winning LiteOn MD5 do not match, and that the LiteOn never achieved an MD5 matching the Plextor in all 29 tests, only proves that you can't always trust what your drive says.

foobar 0.9 vs EAC Secure rip

This is excellent!

Congratulations to Peter for his wonderful (and correctly implemented idea) new development for foobar2000

And thanks to you, Synthetic Soul, for your time and patience.

It is good to have an alternative on ripping

foobar 0.9 vs EAC Secure rip

Reply #32 – 2005-09-30 05:33:04

I conducted a test of foobar 0.9b9's new ripping capability with respect to error detection & correction. The CD used was one which I have had considerable problems with in the past. It is badly scratched and in the past several attempts using EAC's secure mode has been required to successfully rip the CD.
Drive has (from EAC): Accurate Stream, No Cache, No C2.
I ripped in foobar using unlimited drive speed in each of the three modes: disabled, secure, and paranoid. I ripped in EAC using Secure mode verified by AccurateRip. The results shown are only those tracks which did not produce identical md5 hashes in all rips (thanks for the script Synthetic Soul ):

Track 7:
foo-unlimited-disabled: 538df4df83a6fa3a19d82a2329d8fb81
foo-unlimited-secure: 96cb4895b72779d580a5c93f75666c70
foo-unlimited-paranoid: 96cb4895b72779d580a5c93f75666c70
eac-secure-accurate: 96cb4895b72779d580a5c93f75666c70

Track 12:
foo-unlimited-disabled: 2bf60c83f669024b27074e2911fc044e
foo-unlimited-secure: 085538635b06ea6cd035104c5f6f4798
foo-unlimited-paranoid: 7e218d767c5c8810006d54d27ebbafd9
eac-secure-accurate: 7e218d767c5c8810006d54d27ebbafd9

Track 13:
foo-unlimited-disabled: 40107f4c4133c513d69d59946b51250e
foo-unlimited-secure: 240bc6ceaf14ea96f5d06d8795f03a13
foo-unlimited-paranoid: 240bc6ceaf14ea96f5d06d8795f03a13
eac-secure-accurate: 240bc6ceaf14ea96f5d06d8795f03a13

As you can see, fb2k's secure mode failed to detect an error on track 12. However paranoid mode agreed with EAC and so in this limited test and for this drive I'm satisfied that paranoid is as accurate as EAC. It should be noted that secure ripped almost twice as fast a paranoid mode.

Also, my drive had considerable trouble with the "limit drive speed" option when error correction was disabled in foobar. It would get part way into the first track before slowing down to about .3x realtime. I cancelled and didn't try with secure or paranoid modes.

foobar 0.9 vs EAC Secure rip

Reply #33 – 2005-09-30 11:50:31

Thanks for the support and additional data. The more data the better.

The only other point I would raise in krazy's test is that EAC also had the most problem with track 12 - the track which unlimited-standard failed on - rating that track's quality as 99.5%, rather than the 99.9% achieved by tracks 7 and 13. So there is some definite correlation between the results.

I need to try to remember some other discs that have caused me problems with EAC. I know my Captain Beefheart Safe as Milk reports errors - there may be some tracks on that disc that have only recoverable errors (I know there are some unrecoverable ones ).

I ripped a CD using Exact Audio Copy and foobar2000 and the first 13 tracks were identical (tested using "shntool cmp -s"). The last tracks, however, were different. When I ran "shntool cmp -s" on them it told me, "Contents of these files are identical (up to the first 8972472 bytes of WAVE data)." When I ran "shntool info" on them it gave me this info:

What could cause those differences in "sector misallignment" values? And which is the better behavior, EAC's or FB2k's?

Synthetic Soul are you sure you set read offsets for all the driver correctly?
One CRC for A drivie and another for B drive may sugest an offset problem IMHO.

The MD5 hash (3adf5ccf2220532a367ffaf031dd56b3) matches for all drives for the pristine test CD*, so I believe so.

bump!!

Are there any options in V0.9 that I should know about. IE - is there anyway to export a log file during a Rip.

My own very limited testing (one cd with one drive) agree with Synthetic Soul's conclusions: neither foobar2000 nor EAC is infallible and foobar2000's standard ripping mode is on par with EAC's secure mode.

Here's the foobar2000 log. Tracks 3 and 5 do not verify with Accuraterip based on Fooaccrip.

10 Tracks Ripped Accurately

Now here's the interesting part. Using foobar2000's bit compare plugin, there are no differences between foobar2000 and EAC's rips of tracks 3 and 5.

Code: [Select]

All tracks decoded fine, no differences found.

Comparing:
"C:\Users\ac25\Desktop\temp\eac\03 - I Don't Understand Anything.flac"
"C:\Users\ac25\Desktop\temp\foobar2000\03 - I Don't Understand Anything.flac"
No differences in decoded data found.

"C:\Users\ac25\Desktop\temp\foobar2000\05 - Get Me.flac"
No differences in decoded data found.

Of course there were differences with the Dbpoweramp rip.

In the future, I'll try other problem discs I have, as well as trying foobar2000's paranoid mode and and using C2 with EAC's secure mode. I hope this testing doesn't fry my drive. I have no idea how to replace a laptop optical drive.

As always kind feedback would be appreciated. Thanks.

foobar 0.9 vs EAC Secure rip

Reply #41 – 2009-04-20 19:42:22

While it is extremely difficult to draw any meaningful conclusions from one disc and one drive, your results definitely show the distinct advantage of using C2 pointers during re-reads when dealing with consistent errors.

However, when dealing with situations where C2 pointers either can't be or aren't being used, I would not always expect all three programs to give the same result, as their methods of re-reading and deciding on correct data are not the same, nor is the way in which each of them asks the drive to seek data.

When using C2 pointers with EAC, I wouldn't normally expect to see a difference when using a drive that reports them reliably, since they aren't used during re-reads. With a drive that doesn't report them reliably, I would normally expect to see fewer accurate rips when they're being used. IOW, the expectation is that EAC will not do any better when configured to make use of C2 pointers. This shouldn't come as a surprise to anyone interested enough in the program enough to become familiar with its settings. There can be surprises, however, since enabling this setting changes more than just asking the drive to return C2 error information. The amount of sectors read at a time changes, causing successive requests of new data to begin at different locations. This causes the areas where the stream is checked for synchronization to change as well. The setting even influences the way flushing is performed when it is enabled. It is entirely possible that using C2 pointers can make a positive difference in getting accurate rips, just not to the extent that it would if they were used during re-reads like they are with dBpoweramp.

I had a problem once with a song sounding like the CD was scratched while it wasn't at all.

No errors occured was the conclusion of foobar. I decided to put the CD into EAC's hands and guess what! It took 3 minutes for one single track to get the same conclusion!

1 CD with EAC: 30 minutes
1 CD witth foobar: 5 minutes

Even if EAC's extraction is theorically the best, I don't give a damn when it can't even detect an error huge like a house!

Unless you can demonstrate that you've configured EAC to work as efficiently as possible given your particular drive, you might be comparing apples and oranges.

I'd challenge those who claim EAC's extraction is theoretically the best.

I wouldn't be so quick to point the finger at the ripping program since it's only part of the equation.

Does Foobar's ripper have to option to make use of C2 pointers, or does it merely re-read each sector a couple times? I don't remember seeing an option for this feature in the settings.

foobar 0.9 vs EAC Secure rip

Reply #46 – 2009-04-20 22:24:22

Currently, foobar2000 relies on consistent results between re-reads only.

I'm not sure what criteria it uses (eg: EAC will report an error if there aren't at least 8 matches out a set of 16 re-reads within the user-configurable number of sets, EAC will report an error; dBpoweramp requires 10 matches out of a user-configurable number of re-reads in order to report the rip as secure).

From the dBpoweramp Rip - interesting, here you have c2 pointers, effectively failing on one frame (25 re-rips, with c2 pointers indicating there is an error, where clearly there was not, hence the best match was then used), yet helping no-doubt on the other frames.

Reply #48 – 2009-04-20 22:47:58

I read that thinking that of the 34 attempts, C2 dropped 25, leaving 9 that passed C2 which was not enough for the rip to be labeled secure.

I have to admit that some of your messages (especially 10 / 11) don't make perfect sense to me.

Reply #49 – 2009-04-20 23:12:38

Yes you are right (I miss-read that 25 frames were being read as total), I will comment each:

Re-rip Frame: 36228 (00:01:15.040) matched 10 / 11 - here re-reading 11 frames, no c2 error flags

Re-rip Frame: 43466 (00:02:51.546) matched 10 / 11 (c2 dropped 5) - here 16 frames are read, c2 highlighed 5 having errors, the c2 dropped are not shown in the x/x,

Re-rip Frame: 43782 (00:02:55.760). Insecure (c2 dropped 25) [c2 best match] - 34 frames are read, c2 highlights 25 as having error, the 7 frames without error match and are used

Notice
