Question to Spoon

[Gbeer7]

I've bought a deluxe boxset album this week, which comes with 4cds. When I rip all the CDs it comes up with a red cross against AR (accurate rip) but a green tick on secure. I have it set to ultra secure rip which went through pass 1 and 2 then ultra 1.

What I want to know is why did it not show as accurate rip? Is I because is not in the Database?

Is ultra secure rip as good as accurate rip ? Are my CDs ok ? Guess what i want to know is am i worrying unnecessarily ?

> Is I because is not in the Database?

Correct

>Is ultra secure rip as good as accurate rip ?

No, as it relies on the drive, and every drive can inform of 100% error free when there are errors.

Re: Question to Spoon

I used to get that red cross with a number in parentheses. I would describe it as a "reverse accurate number", indicating how rips DIDN'T match mine. I stopped getting that a few updates ago. The area where that red cross used to be is now ghosted. I assume it had something to do with the new version of AccurateRip being able to work with multiple pressings.

Re: Question to Spoon

So spoon, sorry.. how can i be sure everything is ok ?

Re: Question to Spoon

The best you can do is rip on a 2nd drive (different make with different offset) and compare the CRCs shown in CD Ripper.

Re: Question to Spoon

Spoon, really ? That sounds very fussy. Why is ultra secure not good enough ? What if the CRC's are different ? Surely if it reads the CD's thats good ?

Taken from AccurateRip.com

"AccurateRip&*8482; is the only Audio CD ripping technology which can verify extracted audio files are 100% free from errors, or put another way...no CD/DVD drive exists today which is able to self detect errors 100% of the time (in PCs or CD players), we call this the audio CD error detection hole (and applies to drives with c2 reporting abilities). "

Re: Question to Spoon

So chances are its ok ?
How would i know if it has an error, Spoon. Also, can you tell if the CD's i PM'd to you are in the database ?

Re: Question to Spoon

So chances are its ok ?

Yes. Most probably it is. I'd say that the likelihood that it is OK, does hardly decrease by the fact that the AR status has an X -- as long as it is for every track on the album. In that case, AccurateRip did most likely compare apples and oranges (in some cases they are very hard to tell apart a priori). However, if all tracks but one match, then you should suspect something might be wrong. (However, there are a lot of errors in the last track, for various reasons. If that is the only one with an X, I would still not panic.)

How would i know if it has an error

You cannot with 100 percent certainty. AccurateRip works by comparing your rip to someone else's rip of the same release (hopefully not the same physical disc, but that is unfortunately possible if you bought it 2nd hand).

If no-one has ripped the same disc, there is nothing to compare to.

If someone has ripped, say, a remastered version of the same music -- and which has the same track lengths -- then they contain different signals and will show up as different; that does not mean that your rip is wrong, merely that AccurateRip cannot tell their tableofcontents apart (of course ... they are the same).

If you rip the same CD in a different drive yourself, and compare CRC's, then you increase the chances of discovering errors (IOW, if the CRCs match, then you have increased your chances of having achieved an error-free rip) -- but if your particular CD has a scratch which makes the drives read a «1111000011110000» as a «0000111100001111» consistently, that error will prevail.


«Accurate» and «Secure» ripping are different second opinions on your rip. Of course, an independent second opinion is better than asking the same person over and over again the same question. In increasing level of independence:
- re-ripping with the same drive (which dBpoweramp does by itself in Secure mode)
- switching drive but maintaining the same physical disc.
- switching disc but maintaing the same physical drive is probably better. As long as the drive is OK, it shouldn't make any difference to switch to another physical drive of the same model.
- switching both drive and disc.

Now AccurateRip does not tell you whether an identical rip was made with the same brand and model, so in theory you might get bogus results verified (there have been some drives that interchange left and right channel, for example, I don't know whether Spoon has eliminated those). But without specific knowledge that this particular drive produces nonsense, there is no way to eliminate that.


But again, in order to get an independent second opinion, then someone must have submitted an independent second opinion (to AccurateRip). Otherwise, re-reading is the best you can do.

Re: Question to Spoon

wow, thank you Porcus. So basically your saying that nothing is really 100% accurate and to chill out, stop worrying and stop asking the same question over and over again ?
I didn't get the *8211 but red AR and cross plus a green tick with secure next to all the tracks on all four discs.
sorry to bang on, I have serve OCD and just worrying about my music collection instead of enjoying it. I fret and doubt :(

Does anyone else worry about this stuff ?!

[Gbeer7]

Re: Question to Spoon

Sorry, anyone help with the above ?

[Porcus]

Re: Question to Spoon

So basically your saying that nothing is really 100% accurate

No ... most rips that show up secure, are indeed 100 percent perfect

AccurateRip does not tell you how close it is to being correct. It either is, or it isn't; and then there are false alarms, or consistent errors.

False alarms: CDs with the same table-of-contents (all tracks of identical length) but different content. (If you tick the enable cross-pressing verification, AR will identify CDs which only differ by the bitstream being moved microseconds to the left or right ...)

Consistent errors: same erroneous result reported from two different sources. Some of these are manufactoring errors, and in many cases, there is no way to tell what is right without access to the original digital file! Luckily, you are unlikely to actually hear this.

chill out, stop worrying and stop asking the same question over and over again ?

Good idea

red AR and cross plus a green tick with secure next to all the tracks on all four discs.

That hardly tells anything about how good the rip is. But you might have misconfigured the drive -- if you rip a few more CDs (common ones, pick a few good old blockbusters if you like mainstream music ...) and never get an AR verification, then there is probably a misconfiguration.

The last CD before that was Ryan Adams and i got a Accuraterip of 20. I have ripped plenty of CD's on this laptop as well. Does that sound like its ok ?

This is a log for one of the discs with X AR and tick with secure. This is what is says in the ID tag, "AccurateRip: Not in database Secure: Yes [D6D316F3]" I'm getting very stressed about this. Concerned i'll have to send the disc's back. Now i'm worried about the other 9000 odd tracks i have ripped. Are they correct?! Feel sick. How would i know if the rip was not right ? Would it sound odd ?

Also i have enable cross-pressing verification, should i not ?

12 Tracks Ripped Securely

Re: Question to Spoon

The last CD before that was Ryan Adams and i got a Accuraterip of 20. I have ripped plenty of CD's on this laptop as well. Does that sound like its ok ?

Sounds totally OK.

This is a log for one of the discs with X AR and tick with secure. This is what is says in the ID tag, "AccurateRip: Not in database Secure: Yes [D6D316F3]"

The title from the log suggest that this is the less-than-a-week old box. As the AccurateRip database is not instantly updated, only every few weeks (I think?), you cannot expect a fresh release to be in the database yet. It isn't there until (1) someone has ripped it, and (2) someone has submitted it (and that by default takes some weeks), and (3) the AccurateRip database is updated.

So this looks just as good as you can get it (until the next update or possibly the next thereafter).

Also i have enable cross-pressing verification, should i not ?

You would normally want to enable it -- it gives matches when a different pressing has the same bitstream only shifted a few bits to the left or right.

Re: Question to Spoon

Thank you Porcus for your time and patience. Does mean alot.

I've ripped my wife's "Steps CD" and got an accuraterip of 3. So would that confirm my drive is configured ok ?

It is a new release. Its Paul McCartney Ram, deluxe boxset that got released last Monday i believe. How could you tell it was a new release ?

I find ripping CD's so stressful, do they work ok, will they make it to the end ok ? etc. Very anxiety provoking for me. (please don't laugh).

If there was an error in the music, how would it show up ? The sad thing is i end up checking music and not listening for pleasure.

So i'm ok and no need to return them ?

Is all this a normal reaction ?!?!
