I would expect that the difference in errors would be a result of the laser and pickup mechanism.

Ie the drives have different lasers, of possibly different power level, and different ability to read the result of that laser.

Also, different drives might have different handling of error correction. I don't know how the drives actually do this (only read up about this a while ago), but drives could e.g. "spend" the ECC bytes differently on error detection/correction in C1/C2 stages.

>And what metadata in dBpowerAMP are you talking about ?

dBpoweramp is able to tag wave files, so when comparing audio files you should always compare the uncomrpessed audio, not the files (ie just running an audio file through CRC32 is wrong), dBpoweramp Reference has a [Calculate CRC] utility codec, select a bunch of file and a CRC32 & MD5 for those files (audio data only) is displayed.

Anyhow back to the point at hand - Accuraterip will help, even if the cd is not in the database, have dBpoweramp to write a ripping log file & check the CRCs from accuraterip, if you rip again, no matter what the drive is that crc is not affected by overreading. Or have dBpoweramp to write AccurateRip ID Tags and compare the CRC in the ID Tags (you cannot use wave as that cannot have accuraterip id tags, any lossless format will though).


Alright, thanks for the information. I think I maybe need to rethink my ripping method, I'm not sure how I will do, maybe I will only use dBpoweramp after all (if Im satisfied with it), it might be too much overkill... And I did mention earlier that the main reason to use multiple ripping software is because of the C2 correction, with an closer thought on the subject, I did realize that I will not rip scratchy cds (regularly). Once I buy a cd I will copy it to the computer (I don't even own an cd player), then I might not use it again.. So most of my cds are in a very good condition, so my need for c2 correction should be quite limited for the most parts. With scratchy cds, I might consider to use multiple ripping programs as an reference... But using 3 reliable drives with dBpoweramp should be enough.

Hopefully dBpoweramp is as good as it seams to be, I have noticed that I have mostly heard opinions/recommendations from an impartial source (spoon), the risk might be that I fool myself into an "false safety". And of course he will talk warmly about his own program since he is the developer which makes him $$$...well..just something that struck me. It would be my biggest mistake to just trust it blindly, I don't want to take any chances. EAC has been under progress under a long time, and is considered to be very stable and reliable. So if I decide to switch to dBpoweramp as my primary cd ripper, I really need trust it's reliability fully, but at present the benefits with dBpoweramp seams overwhelming.

afaik dbpoweramp has been under dev also from a long time. You can also try the trial version. I really like dbpoweramp, i have been using it since a long time ago, and about 1 month ago, bought powerpack version.

My only problem with dbpoweramp is what the hell does "reference version" means? It is really a silly name. (basica, advanced and professional should have been much better names).

Well, why I did think about using 2(3) ripping softwares is mainly cause the C2 correction is handled in a different way in each program, and they do not always generate an unambiguous result.

What Spoon has to say about this is worth repeating:
Quote from: spoon on
>Plextor Px-708a
>Plextor Px-230a (rebaged Benq version)

In my testing neither of these let through a single error (past the c2), and that was ripping 1000's of intentionally damged tracks.

Moving on...

If I had 3 references, my idea was to be able to choose which is "correct", if I get the equal CRC's with let's say EAC/Plextools, I will use these rips...and assume the dBpoweramp rip is not correct, since 2 weight more then 1.
Majority rule is not a good method of determining whether a rip is accurate or not.  This is a major reason why Spoon has put so much effort into rewriting his ripping program and this is why his program is able to get more accurate results than EAC when using drives that provide C2 pointers.

Don't confuse C2 correction with C2 pointers.  All drives will always perform C2 correction when needed regardless of how you have your software configured; it is done internally.  Some drives have the ability to tell your ripping program that if C2 correction was performed as well as the result of the correction.  This information that gets passed along is commonly referred to as a C2 pointer.

EAC has two problems when it comes to C2 pointers.  First, errors that can't be corrected by C2 can go undetected.  This seems to be largely dependent on the make and model of your drive.  Second, when an error that the drive can't correct is detected, EAC will perform re-reads, but it no longer uses C2 pointers to determine whether any of the re-reads are accurate.  Instead, it reverts back to relying on majority rule which does not guarantee good data.

The reference version of dBpowerAMP addresses both of these problems with Ultra-secure passes and the use of C2 pointers durning rereads.

I know that Hi-Fi component manufacturers use the term "reference version" to denote a top-notch product.

could be that then ... but for me "reference" sounds like "basic" ... probably cause english is not my natural language.

Why is the c2 accuracy (as %) very low on the 230a when it let though very few c2 errrors (i comparison to the other drives)?


I have no idea - as I stated, all numbers there are very strange. What firmware version does your test unit have?

I am sure my 230a has the latest firmware (it is in another country to me right now  ).

Free: a functional Ripper and Converter, mp3 encoding missing.

Can not convert mp3 to mp3 with the free version?  The authors use Lame MP3 encoder, don't you?

any idea when the FLAC codec will be updated to 1.1.4?

I'd also like to know this too, 1.1.2 is so old now and 1.1.4 compresses much better and is lots faster too.

use the command line encoder, and the lame exe to get around that if you already have an mp3 license (and im sure everyone has probably payed for ~100 of them)

I think you should inform yourself more before starting to spread such false information. MP3 patents have nothing to do with software patents and they apply in almost (if not all) countries.

Sorry, I must have mixed up something then. Edited my post to prevent spreading this misunderstanding further.
Edit: Just googled around a bit, it's not too difficult to get the wrong impression. Fraunhofer's mp3-patents are often called software patents and in several places it was claimed that these patents are not valid in Germany, though Fraunhofer was trying to enforce them. However, a news report I found strongly suggested otherwise.

Quick question again.  When was the plan to add image+cue support to dBpoweramp?  That's the only thing holding me back from testing it versus EAC.

According to this thread http://forum.dbpoweramp.com/showthread.php?t=11658 not for maybe another YEAR. I was totally waiting for this also. Hard to understand since EAC has had cuesheet implementation for a long time, even plextools. Will have to wait and see I guess.

I had a couple of odd things happen with this.

I just got through converting over 8000 of my FLAC files to MP3 (after discovering the options for keeping folder structure are worded differently to the last release so I have all MP3s in one folder, grrr), for some reason it's lost the tag data on about 12 files?!

There's nothing wrong with these FLAC files, my whole collection has been verified but the converted MP3s had no tags at all for some reason.

Any thoughts?

Hold the mouse over the flac files, does dbpoweramp show the id tags in the popup?
