morituri is a CD ripper aiming for accuracy over speed. Its features are modeled to compare with Exact Audio Copy on Windows.

RATIONALE

For a more detailed rationale, see my wiki page 'The Art of the Rip'.

FEATURES

  • support for MusicBrainz for metadata lookup
  • support for AccurateRip verification
  • detects sample read offset and ability to defeat cache of drives
  • performs test and copy rip
  • detects and rips Hidden Track One Audio
  • templates for file and directory naming
  • support for lossless encoding and lossy encoding or re-encoding of images
  • tagging using GStreamer, including embedding MusicBrainz id's
  • retagging of images
  • plugins for logging
  • for now, only a command line client (rip) is shipped

REQUIREMENTS

  • cdparanoia, for the actual ripping
  • cdrdao, for session, TOC, pregap, and ISRC extraction
  • GStreamer and its python bindings, for encoding
    • gst-plugins-base >= 0.10.22 for appsink
  • python musicbrainz2, for metadata lookup
  • python-setuptools, for plugin support
  • python-cddb, for showing but not using disc info if not in musicbrainz
  • pycdio, for drive identification (optional)

GETTING MORITURI

If you are building from a source tarball or checkout, you can choose to use morituri installed or uninstalled.

  • getting:

    • Change to a directory where you want to put the morituri source code (For example, $HOME/dev/ext or $HOME/prefix/src)

    • source: download tarball, unpack, and change to its directory

    • checkout:

        git clone git://github.com/thomasvs/morituri.git
  cd morituri
  git submodule init
  git submodule update
  ./autogen.sh

  • building:

      ./configure
  make

  • you can now choose to install it or run it uninstalled.

    • installing:

        make install

    • running uninstalled:

        ln -sf `pwd`/misc/morituri-uninstalled $HOME/bin/morituri-git
  morituri-git  # this drops you in a shell where everything is set up to use morituri

RUNNING MORITURI

morituri currently only has a command-line interface called 'rip'

rip is self-documenting. rip -h gives you the basic instructions.

rip implements a tree of commands; for example, the top-level 'changelog' command has a number of sub-commands.

Positioning of arguments is important;

rip cd -d (device) rip

is correct, while

rip cd rip -d (device)

is not, because the -d argument applies to the rip command.

Check the man page (rip(1)) for more information.

RUNNING UNINSTALLED

To make it easier for developers, you can run morituri straight from the source checkout:

./autogen.sh
make
misc/morituri-uninstalled

GETTING STARTED

The simplest way to get started making accurate rips is:

  • pick a relatively popular CD that has a good change of being in the AccurateRip database

  • find the drive's offset by running

      rip offset find

  • wait for it to complete; this might take a while

  • optionally, confirm this offset with two more discs

  • analyze the drive's caching behaviour

      rip drive analyze

  • rip the disc by running one of

      rip cd rip  # uses the offset from configuration file
  rip cd rip --offset (the number you got before)  # manually specified offset

FILING BUGS

morituri's bug tracker is at https://thomas.apestaart.org/morituri/trac/. When filing bugs, please run the failing command with the environment variable RIP_DEBUG set; for example:

RIP_DEBUG=5 rip offset find > morituri.log 2>&1
gzip morituri.log

And attach the gzipped log file to your bug report.

KNOWN ISSUES

  • no GUI yet

GOALS

  • quality over speed
  • support one-command automatic ripping
  • support offline ripping (doing metadata lookup and log rewriting later)
    • separate the info/result about the rip from the metadata/file generation/...

CONFIGURATION FILE

The configuration file is stored according to XDG Base Directory Specification when possible.

It lives in $XDG_CONFIG_HOME/morituri/morituri.conf

The configuration file follows python's ConfigParser syntax. There is a "main" section and zero or more sections starting with "drive:"

  • main section:

    • path_filter_fat: whether to filter path components for FAT file systems
    • path_filter_special: whether to filter path components for special characters

  • drive section: All these values are probed by morituri and should not be edited by hand.

    • defeats_cache: whether this drive can defeat the audio cache
    • read_offset: the read offset of the drive
