|
|
|
Whipper is a Python 2.7 CD-DA ripper based on the [morituri project](https://github.com/thomasvs/morituri) (_CDDA ripper for *nix systems aiming for accuracy over speed_). It enhances morituri which development seems to have halted merging old ignored pull requests, improving it with bugfixes and new features.
|
|
|
|
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](#changelog) files may not be comprehensive).

## Installation
|
|
|
|
Whipper still isn't widely available as an official package in many Linux distributions so, in order to use it, it may be necessary to build it from its source code. 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_.
|
|
|
|
This is a noncomprehensive summary which shows whipper's packaging status (unofficial repositories are probably not included):
|
|
|
|
[](https://repology.org/metapackage/whipper)
|
|
|
|
In case you decide to install whipper using an unofficial repository just keep in mind it is your responsibility to verify that the provided content is safe to use.
|
|
|
|
### Required dependencies
|
|
|
|
Whipper relies on the following packages in order to run correctly and provide all the supported features:
|
|
|
|
- [cd-paranoia](https://www.gnu.org/software/libcdio/), for the actual ripping
|
|
- To avoid bugs it's advised to use `cd-paranoia` **10.2+0.94+2-2**
|
|
- [cdrdao](http://cdrdao.sourceforge.net/), for session, TOC, pre-gap, and ISRC extraction
|
|
- [python-gobject-2](https://packages.debian.org/en/jessie/python-gobject-2), required by `task.py`
|
|
- [python-musicbrainzngs](https://github.com/alastair/python-musicbrainzngs), for metadata lookup
|
|
- [python-mutagen](https://pypi.python.org/pypi/mutagen), for tagging support
|
|
- [python-setuptools](https://pypi.python.org/pypi/setuptools), for installation, plugins support
|
|
- [python-cddb](http://cddb-py.sourceforge.net/), for showing (but not using) metadata if disc information aren't available in the MusicBrainz DB
|
|
- [python-requests](https://pypi.python.org/pypi/requests), for retrieving AccurateRip database entries
|
|
- [pycdio](https://pypi.python.org/pypi/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 `pycdio` **0.20** or **0.21** with `libcdio` ≥ **0.90** ≤ **0.94**. If using `libcdio` **0.83**, which is _too old_ to satisfy all the requirements of whipper, just stick to `pycdio` **0.17**. Altough it needs additional testing, `libcdio` **2.0.0** seems to work fine if used with `pycdio` **2.0.0**. All other combinations aren't guaranteed to work.
|
|
- [libsndfile](http://www.mega-nerd.com/libsndfile/), for reading wav files
|
|
- [flac](https://xiph.org/flac/), for reading flac files
|
|
- [sox](http://sox.sourceforge.net/), for track peak detection
|
|
|
|
### Fetching the source code
|
|
|
|
Change to a directory where you want to put whipper source code (for example, `$HOME/dev/ext` or `$HOME/prefix/src`)
|
|
|
|
```bash
|
|
git clone https://github.com/JoeLametta/whipper.git
|
|
cd whipper
|
|
```
|
|
|
|
### Building the bundled dependencies
|
|
|
|
Whipper uses and packages a slightly different version of the `accuraterip-checksum` tool:
|
|
|
|
You can edit the install path in `config.mk`
|
|
|
|
```bash
|
|
cd src
|
|
make
|
|
sudo make install
|
|
cd ..
|
|
```
|
|
|
|
### Finalizing the installation
|
|
|
|
Install whipper: `python2 setup.py install`
|
|
|
|
Note that, depending on the chosen installation path, this command may require elevated rights.
|
|
|
|
## Usage
|
|
|
|
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.
|
|
|
|
## Getting started
|
|
|
|
The simplest way to get started making accurate rips is:
|
|
|
|
1. Pick a relatively popular CD that has a good chance of being in the AccurateRip database
|
|
2. Analyze the drive's caching behavior
|
|
|
|
`whipper drive analyze`
|
|
|
|
3. Find the drive's offset.
|
|
|
|
Consult the [AccurateRip's CD Drive Offset database](http://www.accuraterip.com/driveoffsets.htm) for your drive. Drive information can be retrieved with `whipper drive list`.
|
|
|
|
`whipper offset find -o insert-numeric-value-here`
|
|
|
|
If you omit the `-o` argument, whipper will try a long, popularity-sorted list of drive offsets.
|
|
|
|
If you can not confirm your drive offset value but wish to set a default regardless, set `read_offset = insert-numeric-value-here` in `whipper.conf`.
|
|
|
|
Offsets confirmed with `whipper offset find` are 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`).
|
|
|
|
4. Rip the disc by running
|
|
|
|
`whipper cd rip`
|
|
|
|
## Configuration file documentation
|
|
|
|
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](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html)
|
|
and [ConfigParser](https://docs.python.org/2/library/configparser.html).
|
|
|
|
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.
|
|
|
|
Example configuration demonstrating all `[main]` and `[musicbrainz]`
|
|
options:
|
|
|
|
```INI
|
|
[main]
|
|
path_filter_fat = True ; replace FAT file system unsafe characters in filenames with _
|
|
path_filter_special = False ; replace special characters in filenames with _
|
|
|
|
[musicbrainz]
|
|
server = musicbrainz.org:80 ; use MusicBrainz server at host[:port]
|
|
|
|
[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
|
|
track_template = new/%%A/%%y - %%d/%%t - %%n ; note: the format char '%' must be represented '%%'
|
|
disc_template = %(track_template)s
|
|
# ...
|
|
```
|
|
|
|
## Running uninstalled
|
|
|
|
To make it easier for developers, you can run whipper straight from the
|
|
source checkout:
|
|
|
|
```bash
|
|
python2 -m whipper -h
|
|
```
|
|
|
|
## Logger plugins
|
|
|
|
Whipper supports using external logger plugins to write rip `.log` files.
|
|
|
|
List available plugins with `whipper cd rip -h`. Specify a logger to rip with by passing `-L loggername`:
|
|
|
|
```bash
|
|
whipper cd rip -L what
|
|
```
|
|
|
|
### Official logger plugins
|
|
|
|
Unfortunately both logger plugins are currently outdated and won't work with latest whipper versions.
|
|
|
|
- [morituri-eaclogger](https://github.com/JoeLametta/morituri-eaclogger) - eac-like logger attempting to maintain strict compatiility with EAC
|
|
- [morituri-whatlogger](https://github.com/RecursiveForest/morituri-whatlogger) - eac-like logger containing the informational enhancements of the yamllogger, originally designed for use on What.CD

### Bug reports & feature requests
|
|
|
|
Please use the [issue tracker](https://github.com/JoeLametta/whipper/issues) to report any bugs or to file feature requests.
|
|
|
|
When filing bug reports, please run the failing command with the environment variable `WHIPPER_DEBUG` set. For example:
|
|
|
|
```bash
|
|
WHIPPER_DEBUG=DEBUG WHIPPER_LOGFILE=whipper.log whipper offset find
|
|
gzip whipper.log
|
|
```
|
|
|
|
And attach the gzipped log file to your bug report.
|
|
|
|
Without `WHIPPER_LOGFILE` set, logging messages will go to stderr. `WHIPPER_DEBUG` accepts a string of the [default python logging levels](https://docs.python.org/2/library/logging.html#logging-levels).
