[paranoia] sample offset?

[Leigh Orf]

Talk about re-resurrecting a thread... well, I too would like to be able
to do 'perfect clone extracts' by somehow accounting for the sample
offset which occurs with my drive. Has anyone gotten any furthur with
this? Seems like it might be a quick patch for someone who knows the
code well.

|   It looks like the link you have above is for _sector_ offsets.
|   Cdparanoia already allows you to specify a sector offset.  From the man
|   page for alpha9.6:
|   
|          The span argument may be  a  simple  track  number  or  an
|          offset/span  specification.   The syntax of an offset/span
|          takes the rough form:
|   
|          1[ww:xx:yy.zz]-2[aa:bb:cc.dd]
|   
|          Here, 1 and 2 are track numbers; the numbers  in  brackets
|          provide  a finer grained offset within a particular track.
|          [aa:bb:cc.dd] is in hours/minutes/seconds/sectors  format.
|          Zero  fields  need  not be specified: [::20], [:20], [20],
|          [20.], etc, would be interpreted as twenty seconds,  [10:]
|          would  be  ten  minutes, [.30] would be thirty sectors (75
|          sectors per second).
|   
|   Unfortunately, there is no way to specify a _sample_ offset -- a sample
|   is 4 bytes.  The patch I posted _tries_ to address this, but it does not
|   work for the final track on a disc.
|   
|   If you do happen to track down a solution, please let me know.  If I can
|   find some free time, I'll take a look at the source again too.
