XLD - Difference between rip from cd and transcode from m4a

Hi there

Short question:
Step 1: rip cd using iTunes to Apple Lossless format
Step 2: transcode m4a files to flac using XLD (accuraterip)
Step 3: rip same cd with XLD to flac (accuraterip)
Step 4: compare the log-files

The Log-Files are not the same, it seems that the transcode from the m4a Files are more accurate than the direct rips...

Can someone explain what's going on?

thanks in advance
Udo

iTunes doesn't support Read Offset, XLD probably does. iTunes doesn't support Write Offset. XLD probably doesn't either (the only one I found that does is EAC).

Have you ever played with these settings?

Search for Read Offset and Write Offset.

eahm, thanks for your reply. No, until now I have not changed this settings. Could the missing Write Offset in iTunes result in a less good result? I'm asking because ripping in iTunes and converting in XLD is much faster as a direct rip in XLD.

Read Offset changes the checksum when you rip and Write Offset changes it when you burn.

I can't say the result is less good, I remember many experts talking about offsets and saying that the audio stream is still the same even if the offset is set differently (reason why iTunes doesn't have an option to change it probably?).

A proper Read Offset means you will have an accurate rip. Rip software query AccurateRip to see if the Offset is set properly (even if AccurateRip itself is not completely accurate). Also ripping software usually calculate AccurateRip automatically.

A proper Write Offset means you could burn the disc and rerip it again and have the very exact copy of the previous rip and the original. Not calculated automatically, there are many tutorial of how to properly calculate it but you'll have to find one since I don't remember which one is the most comprehensive and precise.

Thanks again for your explanations. I think I understand a lot more now.

The offset difference doesn't explain the 5 bad tracks for the XLD rip. The good tracks match the confidence levels of the other rip for the same AccurateRip ID. The XLD rip log might be more helpful (to someone more familiar with that program) to diagnose what might be wrong with the rip method or settings than the AccurateRip results alone.

Does it happen with that CD alone, which could be somewhat a little defective (and the iTunes is a one lucky shot) or is it a consistent behavior? Or maybe a defective reader. By the way, iTunes ripping and XLD burst mode should theorically be the same thing, at a device level (Edit: and so complete a rip at the same speed). Yes, do post the whole log.

korth, yeah... we kept talking about it and I didn't even double check the first post.

Not sure when it was enabled but the current version of XLD for Mac (142.3) does support both Read and Write Offset, adjustable in the "CD Rip" and CD Burn" preferences.

I've made some more tests. In my environment the behavior is reproducible.

I used the same CD as in my first post and another one. The complete logs (from the first CD) are shown below. Thanks for any comments on this.

XLD - Difference between rip from cd and transcode from m4a

Reply #10
A sample-by-sample comparison might be shed some light..

To satisfy a hunch, could you check to see if there was a channel reversal in any of the errantly-ripped tracks?

Please also try XLD in burst mode.

Hi greynol

Tried XLD with Ripper Mode: Burst, the log is below (->All tracks accurately ripped.)

I'm quite new to this stuff, can you tell me how I can check if there was a channel reversal?

I'll try to check for channel reversals. Thanks for the codebox hint.

What does an accurate rip in burst mode mean, compared to the XLD secure ripper?

Smudeli,
Did you try using the secure ripper with 'Make use of C2 pointers' turned off?

(Settings from the rip log above: the good rip)

I'd still like to know how the files differ. Asking the drive to return C2 pointers should not affect its ability to return error-free data; rather, this suggests a problem with implementation somewhere.

I had a similar problem with XLD way back in 2008, and I posted comparison logs here:

http://www.hydrogenaudio.org/forums/index....st&p=589849

To wit: never bother to enable C2 pointers on XLD. It doesn't work. My subsequent experimentation with drives that are acknowledged to successfully report C2 information showed that they still didn't play nice with XLD, returning different CRCs. I didn't have that problem when using those very same drives with dBpoweramp.
