Overread question

I have a pioneer DWR-111D drive, which can overread into lead-out (according to the EAC test), and has an offset of +48 samples. I've read in the EAC knowledge base, that if my drive has a positive offset correctino number, and it can overread into lead out, i can use the overread feature of eac.

My question is that can my drive read the whole lead-in and lead-out part of the disc, or only reads 48 sanples of the lead-in and the whole lead-out?

If your drive can overread then it should be able to do so beyond the size of the offset, yes.

You also mentioned overreading into the lead-in.  Did EAC's test say the drive could overread in both directions?

It says, that it can only overread into lead-out. But according to the hydrogenaudio knowledge base, if a drive has positive offset correction, then if it can read into lead-out, it can overread.

Overread Lead-In and Lead-Out : Press the button that says "Detect read sample offset correction". Enable this setting if it says your drive can overread from both the Lead-In and Lead-Out or if it says Lead-Out and your offset correction is positive or if it says Lead-In and your offset correction is negative. Otherwise disable it.

Yes, I'm the one who wrote that.

It does not mean that a just because a drive that can overread into the lead-out it can also overread into the lead-in.

EAC will tell you if a drive can overread into the lead-out, lead-in, both or none.  This test has nothing to do with the size of the offset or it's direction.  Whether you can safely enable the overreading setting does depend on the results of this test and the direction of the offset, however.

As a follow-up, if you configure your drive with a positive offset correction, it will never attempt to read from the lead-in, regardless of the overreading setting.  The converse holds true as well.

Since the last reply, I came up with an other question: with how many samples would the file with overread longer than the file without overreading (and of course without filling missing samples with silence)?
