    Issues ripping audiobook CDs

    Hello,

    I am having consistent issues ripping audiobook CDs, especially the last few tracks of any disk. The disks don't appear to be badly damaged, and CD players seem to be able to play them without noticeable gaps or stuttering. However, DBPoweramp has to re-rip several hundred frames per track, and takes a very long time. I have seen this behaviour with two different optical drives (one Pioneer DVD drive, one Samsung Blu-Ray drive).

    Typically, but not always, the disks are not found in the Accurate Rip database. It has happened many times, with different disks.

    Is there a reasonable set of secure rip settings I can use to instruct DBPoweramp to emulate a standard CD player if a bit perfect rip is not possible?

    I tried playing with the secure settings, but can't seem to get the result I want. Either it takes forever, or the process aborts.

    Any suggestions would be helpful.

    Also, is there some way to reset the secure rip settings to default? I messed them up, and forgot to note what the detaults were. I can't find any way to reset to default.

    Thanks,

    Nike

    I notice that the option to interpolate unrecoverable frames is unchecked in the page linked -- why is this?

    Also, if secure ripping is aborted, does the drive process revert to burst mode? Or does the whole process terminate without writing any file? It is not clear to me what if anything is saved, in the event that a secure rip fails.

    Most drives self interpolate better.

    Yes if aborted the data is what is already ripped, which is burst.

    Thanks. I tried this method, but I get errors like this:

    I guess this indicates a damaged disk, and no file was saved, but I am wondering whether there is a way to tell the ripper to simply go in to burst mode, or to emulate a CD player and interpolate the missing frames (as CD players can play the disk fine).

    Is this possible? Or is there some other option?

    It does indicate the disc is damaged, or has manufacturing defects. You can switch to burst mode manually for such CDs.

    Thank you.

    I tried another optical drive, and this time the tracks were ripped but came out as inaccurate. The ripper also reported that the tracks were not in the Accurate Rip Database, which is weird, because the preceding tracks were all listed as Accurate and the CD is listed in as being in the database (see screen grab). Is this a pressing/manufacturing issue? Screen Shot 2020-01-14 at 7.59.44 AM.jpg

    Just to be clear, what do the terms "inaccurate" and "insecure" mean, precisely? What is the difference between the two?

    And what is the difference between "secure" and "ultra secure"?

    Finally, does burst mode ripping mean that the ripper emulates a CD player?

    Thanks for all the help! It's much appreciated.

    Statuses are listed here:

    Ultra secure just tries more times to spot errors, most people do not need this.

    Burst accepts what-ever the CD drive produces, small errors tend to be interpolated to silence by the drive.

    The other person might have had rip errors on the last tracks, hence why they are not in the database.
