[Paranoia] Need help making a decent audio copy

[Sebastian]

Hi!

Thanks for your reply. I have never seen '-' afaik. But '+' I get
occasionally. I tried -O 667, but then I had problems with the last
track. cdparanoia just stalls and doesn't finish:

(== PROGRESS == [                             > | 339399 00 ] == :-0
==)

But then I read some more on the web and it came to my mind I went into
the wrong direction. I came to think of it like I already have an offset
of +667 and with -O 667 I would add another 667 samples to the offset,
resulting in a total of 1334 samples offset. So I tried -O -667 instead.
But using a negative value results in the first track not being ripped.
Now it stalls in the beginning:

(== PROGRESS == [>                             0| ...... 06 ] == :-0 0
==)

On the web there were 18 people reporting this drive's offset as 667,
though. But anyway, it doesn't work.

Another thing I read is that one should'nt try to fix the offset,
because not only the drives can have one but also every CD has one. Not
every CD seems to start at the same point that is, because maybe this
isn't specified in the red book, or CD makers do not exactly follow the
book. Well, I don't really understand this matter. But it still would be
nice if when you rip a wav on two different machines they come out
exactly the same (same md5 sums).

Cheers

Sebastian
