INXS - Welcome to Wherever You Are: incorrect write-offset & track splitting

[bikerspade]

Similar to https://github.com/superg/redumper/issues/134 redumper determines the disc write offset to be +6838, and moves data out of lead-out

However, this results in incorrect track splitting, where the beginning samples of track 5 are heard at the end of track 4.

Using --force-offset=0 seems to result in correct track splitting.

[Deterous]

Given that the offset is relatively small (<10000), this seems to be a design decision of redumper rather than a bug. The spec says that no data should be in the lead-out, and following the spec results in this "bad split". If there's a way to determine that data in the lead-out is due to bad mastering (disc doesn't follow spec) and not disc write offset (disc follows spec), then I am not aware of it.

[superg]

Up to 2 seconds of the non zero lead-out will be shifted (88200 samples).
