After a weekend full of refactoring code, adding tasks, and putting pieces together, combined with last night’s airplane session, I have my first AccurateRip-verified rip done:

This version does full index scanning (gap detection) using cdrdao, read and verify using cdparanoia and an offset, .cue file writing (non-compliant .cue, which means gaps/index 00 are appended at end of previous track), and AccurateRip verification.

It doesn’t do Hidden Track One Audio ripping yet (which will now be easy to add, but I forgot to bring a CD that actually has a HTOA to test with), doesn’t do any kind of metadata lookup (so tracks are named track%02d.wav), no encoding to other formats, and no log file generation.

But those are the easy parts…

  1. Is this just a script you are playing around with or a package?

    Comment by AW — 2009-5-5 @ 8:26 pm

  2. Any code available we to play around with?

  3. @AW, @Qball: sure there’s code to play with! Browse around at https://thomas.apestaart.org/thomas/trac/browser/src/morituri/trunk or check out using
    svn co https://thomas.apestaart.org/thomas/svn/src/morituri/trunk morituri

    all the examples are in examples/ and I plan to over the course of the next week package it up, create a simple frontend binary that is a bit easier to discover and start playing around with, but in the meantime feel free to try things and ask me stuff.

  4. Cool I got the ARcalibrate to work. (after having to add an option to specify cdrom drive).
    And it nicely detected the right offset for my drive (one I knew the offset off) now seeing if it can figure out the one I don’t know.

  5. What is the point of calculating TRMs? MusicBrainz has dropped support for TRMs since November 2008 in favor of PUIDs.

  6. Now all we need is a free (non proprietary) AR database
