Whipper is a Python 3 (3.6+) CD-DA ripper based on the morituri project (CDDA ripper for *nix systems aiming for accuracy over speed). It started just as a fork of morituri - which development seems to have halted - merging old ignored pull requests, improving it with bugfixes and new features. Nowadays whipper's codebase diverges significantly from morituri's one.
Whipper is currently developed and tested only on Linux distributions but may work fine on other *nix OSes too.
In order to track whipper's latest changes it's advised to check its commit history (README and CHANGELOG files may not be comprehensive).

- Detects correct read offset (in samples)
- Detects whether ripped media is a CD-R
- Has ability to defeat cache of drives
- Performs Test & Copy rips
- Verifies rip accuracy using the AccurateRip database
- Uses MusicBrainz for metadata lookup
- Supports reading the pre-emphasis flag embedded into some CDs (and correctly tags the resulting rip)
- Currently whipper only reports the pre-emphasis flag value stored in the TOC
- Detects and rips non digitally silent Hidden Track One Audio (HTOA)
- Provides batch ripping capabilities
- Provides templates for file and directory naming
- Supports lossless encoding of ripped audio tracks (FLAC)
- Allows extensibility through external logger plugins

Whipper still isn't available as an official package in every Linux distributions so, in order to use it, it may be necessary to build it from its source code.
You can easily install whipper without needing to care about the required dependencies by making use of the automatically built images hosted on Docker Hub:
docker pull whipperteam/whipper
Please note that, right now, Docker Hub only builds whipper images for the amd64 architecture: if you intend to use them on a different one, you'll need to build the images locally (as explained below).
Building the Docker image locally is required in order to make it work on Arch Linux (and its derivatives) because of a group permission issue (for more details see issue #499).
To build the Docker image locally just issue the following command (it relies on the Dockerfile included in whipper's repository):
optical_gid=$(getent group optical | cut -d: -f3) uid=$(id -u) docker build --build-arg optical_gid --build-arg uid -t whipperteam/whipper .
It's recommended to create an alias for a convenient usage:
alias whipper="docker run -ti --rm --device=/dev/cdrom \
--mount type=bind,source=${HOME}/.config/whipper,target=/home/worker/.config/whipper \
--mount type=bind,source=${PWD}/output,target=/output \
whipperteam/whipper"You should put this e.g. into your .bash_aliases. Also keep in mind to replace the path definitions to something that fits to your needs (e.g. replace … -v ${PWD}/output:/output … with … -v ${HOME}/ripped:/output \ …).
Essentially, what this does is to map the /home/worker/.config/whipper and ${PWD}/output (or whatever other directory you specified) on your host system to locations inside the Docker container where the files can be written and read. These directories need to exist on your system before you can run the container:
mkdir -p "${HOME}/.config/whipper" "${PWD}/output"
Please note that the example alias written above only provides access to a single disc drive: if you've got many you will need to customise it in order to use all of them in whipper's Docker container.
Finally, you can test the correct installation as such:
whipper -v
whipper drive list
This is a noncomprehensive summary which shows whipper's packaging status (unofficial repositories are probably not included):
NOTE: if installing whipper from an unofficial repository please keep in mind it is your responsibility to verify that the provided content is safe to use.
If you are building from a source tarball or checkout, you can choose to use whipper installed or uninstalled but first install all the required dependencies.
Whipper relies on the following packages in order to run correctly and provide all the supported features:
- cd-paranoia, for the actual ripping
- To avoid bugs it's advised to use
cd-paranoiaversions ≥ 10.2+0.94+2 - The package named
libcdio-utils, available on older Debian and Ubuntu versions, is affected by a bug: it doesn't include thecd-paranoiabinary (needed by whipper). Starting with Debian bullseye (11) and Ubuntu focal (20.04), a separatecd-paranoiapackage is available which provides the aforementioned binary. For more details on this issue, please check the relevant bug reports: #888053 (Debian), #889803 (Debian) and #1750264 (Ubuntu).
- To avoid bugs it's advised to use
- cdrdao, for session, TOC, pre-gap, and ISRC extraction
- musicbrainzngs, for metadata lookup
- mutagen, for tagging support
- setuptools, for installation, plugins support
- pycdio, for drive identification (required for drive offset and caching behavior to be stored in the configuration file).
- To avoid bugs it's advised to use the most recent
pycdioversion with the correspondinglibcdiorelease or, if stuck on old pycdio versions, 0.20/0.21 withlibcdio≥ 0.90 ≤ 0.94. All other combinations won't probably work.
- To avoid bugs it's advised to use the most recent
- discid, for calculating Musicbrainz disc id.
- ruamel.yaml, for generating well formed YAML report logfiles
- libsndfile, for reading wav files
- flac, for reading flac files
- sox, for track peak detection
- git or mercurial
- Required either when running whipper without installing it or when building it from its source code (code cloned from a git/mercurial repository).
Some dependencies aren't available in the PyPI. They can be probably installed using your distribution's package manager:
PyPI installable dependencies are listed in the requirements.txt file and can be installed issuing the following command:
pip3 install -r requirements.txt
- Pillow, for completely supporting the cover art feature (
embedandcompleteoption values won't work otherwise). - docutils, to build the man pages.
These dependencies are not listed in the requirements.txt. To install them, just issue the following command:
pip3 install Pillow docutils
Change to a directory where you want to put whipper source code (for example, $HOME/dev/ext or $HOME/prefix/src)
git clone https://github.com/whipper-team/whipper.git
cd whipperInstall whipper: python3 setup.py install
Note that, depending on the chosen installation path, this command may require elevated rights.
To build the man pages, follow the instructions in the relevant README which is located in the man subfolder.
Whipper currently only has a command-line interface called whipper which is self-documenting: whipper -h gives you the basic instructions.
Whipper implements a tree of commands: for example, the top-level whipper command has a number of sub-commands.
Positioning of arguments is important:
whipper cd -d (device) rip
is correct, while
whipper cd rip -d (device)
is not, because the -d argument applies to the cd command.
A more complete set of usage instructions can be found in the whipper man pages.
The simplest way to get started making accurate rips is:
-
Pick a relatively popular CD that has a good chance of being in the AccurateRip database
-
Analyze the drive's caching behavior
whipper drive analyze -
Find the drive's offset.
Consult the AccurateRip's CD Drive Offset database for your drive. Drive information can be retrieved with
whipper drive list.whipper offset find -o insert-numeric-value-hereIf you omit the
-oargument, whipper will try a long, popularity-sorted list of drive offsets.Please note that whipper's offset find feature is quite primitive so it may not always achieve its task: in this case using the value listed in AccurateRip's CD Drive Offset database should be enough.
If you can not confirm your drive offset value but wish to set a default regardless, set
read_offset = insert-numeric-value-hereinwhipper.conf.Offsets confirmed with
whipper offset findare automatically written to the configuration file.If specifying the offset manually, please note that: if positive it must be written as a number without sign (ex:
+102->102), if negative it must include the sign too (ex:-102->-102). -
Rip the disc by running
whipper cd rip
The configuration file is stored in $XDG_CONFIG_HOME/whipper/whipper.conf, or $HOME/.config/whipper/whipper.conf if $XDG_CONFIG_HOME is undefined.
See XDG Base Directory
Specification
and ConfigParser with inline_comment_prefixes=(';').
The configuration file consists of newline-delineated [sections]
containing key = value pairs. The sections [main] and
[musicbrainz] are special config sections for options not accessible
from the command line interface. Sections beginning with drive are
written by whipper; certain values should not be edited. Inline comments can be added using ;.
Example configuration demonstrating all [main] and [musicbrainz]
options:
[main]
path_filter_dot = True ; replace leading dot with _
path_filter_posix = True ; replace illegal chars in *nix OSes with _
path_filter_vfat = False ; replace illegal chars in VFAT filesystems with _
path_filter_whitespace = False ; replace all whitespace chars with _
path_filter_printable = False ; replace all non printable ASCII chars with _
[musicbrainz]
server = https://musicbrainz.org ; use MusicBrainz server at host[:port]
# use http as scheme if connecting to a plain http server. Example below:
# server = http://example.com:8080
[drive:HL-20]
defeats_cache = True ; whether the drive is capable of defeating the audio cache
read_offset = 6 ; drive read offset in positive/negative frames (no leading +)
# do not edit the values 'vendor', 'model', and 'release'; they are used by whipper to match the drive
# command line defaults for `whipper cd rip`
[whipper.cd.rip]
unknown = True
output_directory = ~/My Music
# Note: the format char '%' must be represented '%%'.
# Do not add inline comments with an unescaped '%' character (else an 'InterpolationSyntaxError' will occur).
track_template = new/%%A/%%y - %%d/%%t - %%n
disc_template = new/%%A/%%y - %%d/%%A - %%d
# ...To make it easier for developers, you can run whipper straight from the source checkout:
python3 -m whipper -hWhipper allows using external logger plugins to customize the template of .log files.
The available plugins can be listed with whipper cd rip -h. Specify a logger to rip with by passing -L loggername:
whipper cd rip -L eacWhipper searches for logger plugins in the following paths:
-
$XDG_DATA_HOME/whipper/plugins -
Paths returned by the following Python instruction:
[x + '/whipper/plugins' for x in site.getsitepackages()] -
If whipper is run in a
virtualenv, it will use these alternative instructions (fromdistutils.sysconfig):get_python_lib(plat_specific=False, standard_lib=False, prefix='/usr/local') + '/whipper/plugins'get_python_lib(plat_specific=False, standard_lib=False) + '/whipper/plugins'
On a default Debian/Ubuntu installation, the following paths are searched by whipper:
$HOME/.local/share/whipper/plugins/usr/local/lib/python3.X/dist-packages/whipper/plugins/usr/lib/python3.X/dist-packages/whipper/plugins
Where X stands for the minor version of the Python 3 release available on the system.
Please note that locally installed logger plugins won't be recognized when whipper has been installed through the official Docker image.
I suggest using whipper's default logger unless you've got particular requirements.
