Rubyripper
Introduction
What is Rubyripper? Rubyripper is a digital audio extraction algorithm that uses cdparanoia or cdda2wav in a sophisticated way to make sure that the rip is done succesfully and accuratly. It is very similiar to EAC. Rubyripper is written in the python programming language.
It's currently available for Linux (partial BSD support). OSX will most likely be supported in the near future. The source (same as executable) is published under the GPL license.
- UPDATE: New version 0.1.1 was released on 12 February 2006.
- UPDATE: New version 0.1.0 was released on 5 November 2005.
Features
- A GTK2 user interface.
- CDDB-info is fetched via the ruby-freedb module.
- Codecs supported are FLAC, Vorbis, MP3, and Wavpack
- Multiple codecs can be used in one run
- You can specific the output directory
Correcation mechanism
Rubyripper correction mechanism goes beyond that of cdparanoia. Every track gets ripped at least twice and is byte compared with the Ruby cmp feature. If any differences are found, each of the 1,000 bytes of the two files is compared. The next trial run looks to see if differing positions or a match can be found. (1,000 bytes is about 0.006 seconds)
Installation
Make sure to have ruby-freedb, ruby-libglade2 and cdparanoia installed as a minimum. You can optionally choose for Lame, Vorbis or FLAC, depending on the codec you wish to use.
Then download Rubyripper: http://rubyforge.org/projects/rubyripper/
Documentation of some of the ripping logic used can be found at:
http://rubyforge.org/docman/view.php/1284/310/Rubyripper's%20ripping%20logic.pdf
Currently there isn't an official installer available. Usage from a terminal or console:
cd <download_dir> (Go to the directory where you saved the downloaded archive)tar xfj <filename_download> (Unpack the archive)cd rubyripper-<version> (Move into the just unpacked directory)chmod +x rubyripper.rb (Make rubyripper.rb executable)./rubyripper.rb (Launch executable)
If Rubyripper doesn't start make sure the dependencies are ok.
