Ok - so I created an EAC test CD (write offset 0) and tested the read offset correction which showed a result of 0. AccurateRip had determined a read offset of +6 for my drive previously. When you test read the burned EAC test CD you have to uncheck "Use AccurateRip with this drive" to be able to do it so what good does knowing the AccurateRip determined value (+6) do you at this point? In any case, would my write offset would be 0 as well (since there is no opposite of 0)?

wyhiwyg doesn't know what he's talking about.

Your write samples offset is -6.

Did anyone read my my previous post?
The number given from a test CD burned with a write samples offset of 0 is your combined read/write offset correction.

Thx for clarifying that What wyhiwyg posted sounded way too simple to be true so that's why I asked.

Another question - this only applies when using the exact same reader and writer? For example, if I were to extract/rip audio files with a different burner and burn them on my burner (or vice versa) the read/write offsets wouldn't apply anymore right? But if I rip and burn an audio CD in my system with the same burner (with the correct read/write offsets) I'll be able to get a 1:1 copy?

Thx for the help..........

You're welcome.

With the write samples offset correctly configured you will be able to burn a disc without introducing an additional(*) offset regardless of what drive did the ripping.

(*) If the drive used to do the ripping introduced an offset then this won't be corrected.

I can't understand... so what serves this number for in AccurateRip database????

SAMSUNG - CD-R-RW SW-252S +6 63 100%

???

So this +6 is to be placed here or do I have to make calculations?


And why there is no database for Write Offset?

I have an LG drive. AccurateRip returns a value of +667 for the read offset. I had previously determined my write offset to be zero by write, ripping and comparing waves and found it to be zero. However, I wanted to create a testCD to verify everything.

I created a test CD using a write offset of zero (which happens to be my drives CORRECT write offset). I then tested the read offset and it returned +667 and so did AccurateRip, which would make my write offset equal to zero. Am I correct?

Also, because I burned the test CD with a write offset of zero AND since this is the correct write offset for my drive, can't I use this same CD on any drive to determine the correct numbers?

The object is to be able to setup several drives without burning anymore CDs. I have a laptop where AccurateRip is grayed out. I used the test CD created earlier and it gave me a +102 for the combined, but since AccurateRip is greyed out, how do I determine the write offset without burning, ripping and comparing waves?

Thanks!

It can be used to determine any drive's read sample offset correction using EAC's internal test, yes.

When determining the write samples offset for each new burner, you'll have to create a new test CD. There are no two ways about it. You should not rely on AccurateRip when using EAC's internal tests for determining offset corrections, or do you trust people who submit results to the database from CD-R? I certainly don't.

Good point.

Just so that I'm clear, I do trust AR to determine a drive's read offset correction, just not when using an EAC Offset Test CD. This isn't to say that there aren't properly offset-corrected submissions to the database for the test CD and that these won't work when the correct offset for your drive also exists in the database. Remember, AR essentially works on positive hits.

When the proper offset for your drive doesn't exist in the database, then things can get a bit more complicated. Of course AR will prompt you for additional discs for confirmation, but using a CD-R, like using multiple discs from a boxed-set, can get a bit dicey.
