Common sense would suggest you remove the unnecessary closed parenthesis...

http://en.wikipedia.org/wiki/CIRC

See that that wasn't right and then try some disambiguation...

...and then choose the one that you've been told.

Of course it's much easier to pretend that there isn't some article out there that actually addresses the point you're afraid to concede.

All well and good, but I'm still waiting to see a video of someone drilling holes in a disc and then ripping the data.

jayess, I will try to explain, although you really could just read about CIRC elsewhere, as has been suggested multiple times.

The audio samples on the CD aren't written "raw" and sequentially into the pits and lands. If they were, then you'd be right to assume any unreadable spot, be it due to a pinhole or not, would likely be an unrecoverable loss. But in reality, before being turned into pits and lands, the samples are interleaved with other info (timecode, secondary data streams, sync data), so it's not even guaranteed that every pinhole is necessarily "on a sample".

On top of that, and more importantly, all this data is further subjected to CIRC coding, which bloats the data slightly to add some checksum-like codes (to oversimplify a little), and shuffles everything kind of like a deck of cards. The bits for a given sample are thus spread out over a wide area; they're not concentrated in a single spot. The result is that there can be random, occasional tiny errors, as well as completely unreadable bursts of pits and lands, even a straight-up gap of over 2 millimeters, and yet the original info encoded therein can be fully recovered through some virtual sudoku, 100% accurately.

Sure, larger or more frequent holes may exceed the error correction capability of CIRC and result in some undecodable samples. But usually, a significant scratch won't affect a continuous span of samples; rather, it will affect single samples spaced somewhat far apart. In a real CD player, these samples can usually be easily interpolated (e.g. as being halfway between adjacent, undamaged samples) and the result may not be 100% correct, but will be audibly indistinguishable from error-free data. Only when samples can't be interpolated, in the most severe cases, do you get audible glitches during playback. In a CD drive, during DAE (ripping), interpolation isn't normally attempted, so it's quite possible for a lightly damaged disc to play just fine but not rip error-free. "Secure" ripping software can compensate for this, to a degree, with various re-reading strategies.

There's more to know, but hopefully this helps you understand why you shouldn't consider pinholes to be a major threat to the integrity of the music encoded on the disc.

Yup. Not to mention the user-error in mentioning Wasabi (Winamp 3/5 API for skins and new plugins) versus WASAPI (Audio API in Windows Vista/7/8).



He insists on mentioning an extreme case (which can happen, I had an old Data CD damaged by a young nephew of mine, when he tried to "draw" with a pen on the label side and made several lines where one could see through).
"pin holes visible when looking to a light" compared to this is minimal.

That's what I've been saying all along and it seems to keep drawing disagreement for some reason. If you don't buy used discs with scratches or pinholes, there is no problem ripping them.

There is a couple of good vids on CD error correction:

I still standby my point that while a player can correct (quiet) these errors during playback of music, it frequently can't correct the data to make perfect rips that match Accuraterip.

It is also quite possible for a damaged disc – so damaged that quite a few physical pits are completely destroyed – to not only play just fine, but to rip error free, to precisely the same bitstream as a pristine copy of the same disc.

You still seem to think that “correct” = “quiet”? It isn't.
– Interpolating an error is done to make it less annoying, less audible, or at best, less likely to be audible. 
– Correcting an error means that bit(s) on the CD are wrong, yet the rip is perfect in the sense that it would match any comparison of the resulting files with ones read from a pristine disc. 


This is the difference between “you are wrong, so STFU”, and “you are wrong, here's the fix, now you are right”. A CD has information to do the latter, but only to a certain extent. Kinda like this thread, I'd say.

I'm going to post some tests I'm doing right now when I finish in a new thread, so the pictures and data isn't buried from people seeing it. But basically, I put two identical copes of an old, chrome top, Elton John CD on a scanner to show the holes, and then I'm going to rip both copies with three different drives and post the results and pictures.

1) Why do, both discs, have holes in almost the same positions? (Concretely, top part. Is that a consequence of the scanner not being clean?)
2) Do you realize that they are different pressings? (At least, different discs).
3) With two of the drives, you get good AR results with CD1 but not with CD2, and the third drive reports failure with both discs.

It would be interesting to find out what is the difference. Take the same ripped track from each CD and verify if the content is different as a whole, or just different in some places. (I'm not sure what to recommend for this, HEX editor with fc /b , audio editor and invert signal... Both have its pros and cons)

If it is really on very concrete parts of the track, then we could determine it's a rip failure. Else, it's obviously not a failure in ripping but something else.

OK, but if a particular disc/drive/ripper/rip-option combo has trouble with a disc that has only pinholes (no other dust or scratches), how do you know it was the pinholes? What makes a disc unreadable isn't necessarily visible to the eye, and isn't even necessarily indicative of a fault on the disc; different drives handle different types of defects better than others.

I have a CD here (made by Discovery Systems) that has no pinholes or scratches; it looks absolutely pristine, but has some kind of manufacturing defect (I can only assume) which make most of its tracks unreadable in any drive or player. If it somehow acquires some pinholes down the line, I'd obviously be mistaken if I attributed the disc's problems to them.

And as has been stated, pinhole-laden discs sometimes do rip without error. I have one like this, myself. So even without understanding the details of the CDDA format and its error-correction capabilities, it's clearly a mistake to assume that pinholes guarantee a disc contains "holes in the music" or that it won't rip and play 100% error-free.

If you have a choice between getting a disc with pinholes and getting one without, then surely, why take the risk with the pinholes? Nobody is saying otherwise. We're just saying you're wrong to assume pinholes guarantee problems.

I did clean the scanner with a damp LCD cloth and then a paint brush.

Both discs say they are "MCAD 6321"

But they do report a difference in the number along the opening:

MCAD-6321-5T by JVC for disc 1

MCAD-6321 A60524JB MFG by UNI on disc 2

I saved each rip folder with the disc number and drive; I'll play around with some track comparisons in Foobar.

An ugly question is if these discs are actually different and DBPoweramp can't differentiate that, then the Accuraterip numbers are what? Worthless?

A fair question at this point in regards to ripping accurately and without error is "to what degree?"

A disc with pinholes could give you a confidence of 5, but a truly perfect one would probably be much higher.

Both of these discs obviously have holes, but one is able to achieve a score of 4 and the other is a 1.

That's not how confidence works. The confidence of 5 means that 5 other people ripped the exact same CD (same pressing) and got the exact same result.

Moreover, the new version of AccurateRip does recognize different pressings, as evidenced by your ripping log.

Ok, so what about when it says 5 other people got a 5, but 12 others didn't?

Again, if we have no way of knowing who had what pressing as we are seeing, what good is all this?

I generally make a decision to keep a disc that has the best numbers or seek a replacement for discs that have bad numbers.

And why isn't the "error correction" fixing all these bad rips?

And how do I know about all these different pressings and which are which without having all these different ones?

This stuff is a headache.

Confidence numbers have nothing to do with the physical condition of the disc. A pristine disc can have the same confidence number as one with scratches. If you are using confidence numbers to judge which discs to keep and which to replace, then STOP! You are throwing your money away.

I think this stuff is pretty educational for people that are not as versed as some of the pros in here to show them the nuances of ripping music.

I'm not sure I'm following your logic. If a disc scores basically a zero because it fails to match any other discs, then it basically has a quality problem, does it not? And scratches do not necessarily mean the disc cannot be accurately read, especially if they run from the inside out, versus following the track data path.

Wasting money isn't really an issue. I buy most of my CD's used and probably average $1 per disc, so I'm more concerned about having a good, accurate disc more than anything else. Even if you have to buy the same disc more than once to get a good one at $1 apiece, it's still a bargain over the new price. Of course in extreme cases on difficult to find, expensive discs, you can use select tracks off of each that had high rip scores to make a good copy.

Anyway, check out this wild ride on this good-looking disc.

If a disc scores basically a zero because it fails to match any other discs, then it basically has a quality problem, does it not?


Once again, the confidence numbers have ABSOLUTELY NOTHING to do with the physical condition of the CD. Nothing. Zip. Zilch. Nadda. Zero.

The confidence number are not "rip scores". They are specific to AccurateRip. It tells you that "x" number of people ripped the exact same CD and got the exact same result. That's it. A confidence number of 5 is every bit as reliable as a confidence number of 200.

If the disc does not have an AccurateRip match, it could mean that the disc has not yet been submitted to the AccurateRip database. If that's the case, then what you want is a Secure rip (indicated by a green check mark).

A confidence of 1 is just as reliable as a confidence of 200 provided that it wasn't you own previous submission.

If it was your submission than it is no less reliable an indicator than a successfully secure rip.
