AccurateRip

Hello all, I've been a bit of a lurker for awhile now and only just joined up . I have a bit of a problem. I am in the unfortunate position of not having a Key CD. I found 1 CD that AccurateRip knows but it is a different pressing and failed. I have a few CDs that are on the list but AccurateRip doesn't know them. Is there anything I can do? My drive is listed, it is a PIONEER - DVD-ROM DVD-120 with a +691, or so the database says. Without access to a Key CD can I just use the offset in the database? Would that be better than nothing? I've been through my entire CD collection (well, anything I can find!) and I only got 1 close to hit. I think the problem is I live in Australia and the CDs are pressed here. I tried posting on the AccurateRip forums but no one responded. If anyone can help that would be fantastic. Thanks all!

P.S I'm using dBpowerAMP to find the offset setting so I can then put it into EAC (I use EAC Version 0.9b4).

You can try and use the offset from the database.

There may not be much to gain from it but it should not hurt anything either. At worst you drop a 1/64th of a second of audio someplace.

As for usability, your AC installation won't be configured until you dig up some key disks, so I suppose you won't be able to send in your the results. But should you have some CDs that are in the database (not necessarily key disks) and you get an accurate rip of even one of them, you can rest assured that your offset is set up properly. Then AC will be of some help to you.

But first I'd suggest you borrow as many CDs as you can off your friends to be done with the configuration

Thanks. I might just end up buying a Linkin Park CD (I'm not a fan, it's just the closest thing I like to listen to ) of Amazon. Do you know if their latest CD is the correct pressing to be recognized by AccurateRip? Just wondering, do you use AccurateRip? How widespread is it? Thanks .

Please keep in mind that buying a CD which shows up in the database doesn't mean that the CD will be recognized as such. There are different versions of the CDs.

As far as I can tell, most of the new pressed CDs I used aren't recognized by AccurateRip.

Well, I wish spoon would get around to updating the database and getting the database online. I have submitted an awful lot of discs that were not in the latest db, as I am sure many others have.

That's the old problem with key-CDs, for finding offset in eac, too.

EAC has a built-in key-CD, the EAC-offset-test-CD.
You need only  a CD-writer, which write offset you know..., or which write offset you take from a database.
With burning this one-and-only-key-CD yourselfs (use CD-RW and write eg. 3 eac-offset-test-CDs, maybe with varying write-offsets on purpose, note them, and calculate backwards) , you can find your read and write offsets, until you get concludent results, eg. same like in databases.

Unfortunately the various pressings have various offsets of even the very same CD in different countriesbtw.

Is a properly written EAC-offset-test-cd as key-cd included into accurate rip db ?

I am not a fan either, so I wouldn't know.

Just wondering, do you use AccurateRip? How widespread is it? Thanks :).

I find AC very handy. If the 100,000 CDs in its database are any indication, it is popular enough already.

Just burn one, rip it and submit the result  Then it will be included.

Be very sure to use the correct write offset. Otherwise we'll have nothing but EAC offset CDs giving wrong offsets.
I'm guessing EAC uses no or always the same CD UPC, regardless the write offset setting.
by the way, on the accuraterip site there's this:

I know that I know nothing. But how can I then know that ?

Hm, I have a small question, don't want to start a new thread. What is actually neccessary for a CD to become included in the key list/key CD database ? Is it enough that someone rips the whole CD with "append gaps to previous track" and his drive properly configured and submits the results ? Or even not the whole CD, only some tracks ?
I know that I know nothing. But how can I then know that ?

Only some tracks is enough.

This means every CD that's ever submitted becomes a key CD and there's no difference between 'key CDs' and other CDs which are 'just in the database', all CDs are key discs ?

there is no need to burn 100s of EAC offset test CDs by different people, if 1 or some few are enough.
I could think of, that some experienced EAC people, EAC authorities like Pio and some others, have EAC and Accurate rip, so they could create the EAC offset test CD and submit.

I have a proper EAC offset test CD(-R) myself, und could burn several ones on CD-RW, CD-R, as I have done in past for finding some EAC offsets. But I have never found time, to install or deal with AccurateRip.

Every key disc in the AccurateRip database is a db entry, but not every db entry is a key disc. I submitted some 40-50 CDs to the db and confirmed they are there; yet only about 15 are on the key disc list.

At any rate, with ~10,000 CDs on the list already no more key discs are accepted, so the point of this discussion is moot.

Well that just sucks. No offence but not all of us live in the US and get the correct pressings. Unless there is some CD that will be the correct version 100% I might just have to give this a miss.

Is it only the list that is no longer updated or are there also no new key discs created ?
10 000 seems to be much, but it's far too few, since there are so much CDs giving wrong offsets or not being recognized etc.
In my collection of factory-pressed CDs there's only 1 key disc giving the correct offset so far (and I'm very lucky with that, because they are only 30 or so). Since today's CDs are so shitty, there are perhaps many people having only so few CDs.

The key discs are always updated (a key disc needs atleast 5 tracks over a certain length), it is just the page that shows all 10,000 keys discs is no longer updated as it is getting too big 400KB (and takes to long to generate).

After wondering a long time about it, I came to the conclusion that none should submit a self-written EAC offset CD. What we'd actually do is reducing the number of key discs required from 3 to 2, because everyone can use his/her (possibly wrong) write offset. (Under the condition that EAC always writes the same on the CD except the offset and accuraterip then creates the same disc IDs) I would have almost done it.

Considering this information, how often should we be downloading the database?  Is there a mailing list that sends out notifications that the database has been updated and should be reinstalled?
