I tried to search through the forums, but I must not be using the proper search strings. So please excuse me if this has been brought up before. I've been using EAC for years (by no means a power use, but I get good rips) and I've recently been looking into XLD since I use my MacBook more often than my PC desktop.

I'm trying to figure out the proper settings so that I can get identical rips from both EAC and XLD. I tried to do this earlier but with no success. I ripped a CD with EAC and generated an MD5 for the wav files. I then ripped the same CD with XLD, but they didn't pass the MD5 verification and when I generated a new MD5 on my Mac to compare, the values were completely different.

Is this not a valid test? Is there a better way to go about doing this? If so, what do my settings need to be for XLD to ensure that tracks ripped with that program will be the same as if they were done in EAC?

Many thanks

Have you made sure that you have the correct offset configured for each of your drives?

Although md5 verification should work, I would make sure that the 32-bit CRCs for the raw PCM data between the two programs match and that null samples are being used in the calculations.

I noticed that I needed to upgrade my version of EAC, which I did, and I also noticed that I needed to set the offset correction. Unfortunately, my cd drive isn't listed on the AccurateRip list (ASUS - CD-S520/A5) and I keep getting different offset values for Key discs I put in the drive.

Is there a sticky somewhere that I'm missing that helps troubleshoot or explains how to deal with these issues? I have a feeling this isn't the first time these questions have been asked, and the veterans here probably get tired of them....

Thanks for any help

EDIT:
I went back and configured the CD/DVD drive on my PC (I never use it because it pretty much sucks) and was able to get, what I believe is the proper set up rather easily. I did a test rip and the results are as follows:

Now it looks to me that the CRC hashes are the same and legit, I just want to make sure I'm reading this properly. Am I on my way, or is there more work to be done? Any help is appreciated.

Cheers,

Are you using EAC's built-in test for determining offsets, or the automatic AccurateRip configuration? Either way you can find your answer here:
http://wiki.hydrogenaudio.org/index.php?ti...p#Drive_Options

Unfortunately, getting inconsistent results is perfectly normal. Different pressings of the same disc will have different offsets.

As for your drive, I have an ASUS 40X and an ASUS 50X. Both require a read samples offset correction of +1858, but your 52X can easily be different.

Safest (but slow) settings:
CDParanoia mode
No C2
No Old CDParanoia
Offset (drive specific)
Query AccurateRip
Verify suspicious sectors
Test before copy (when not in AccurateRip)

XLD is an excellent application. I like it very much. Finally the new version supports batch conversion.

The troubles you had were probably as suggested solely caused by different offsets.

What about the "Scan ReplayGain" option? Any special reason to ignore it?

Thanks in advance
