Cdparanoia

cdparanoia is a compact disc ripper for Unixes and BeOS. It was designed to be a minimalistic, high-quality CD ripper that would be able to compensate for and adjust to poor hardware to produce a flawless rip.

Design

The Paranoia library is the foundation of the project and does most of the work, whereas the application cdparanoia is merely an application frontend to the Paranoia library. The current stable release of the Paranoia library is called Paranoia III. The guiding principle of cdparanoia's design is "Too many features spoil the broth". cdparanoia is designed to rip correctly and know as much as possible about the CD-ROM hardware instead of implementing extraneous features such as a graphical user interface or a CDDB interface.

Development history

cdparanoia is developed by Xiph.org, the same team behind Vorbis and Theora, who provide public subversion read-only access. The project began as a set of patches to cdda2wav, called Paranoia I and II that provided limited error correction and supported few drives. Paranoia III, (January 1998), was a standalone library for BeOS and Linux; some claim it has a difficult to extend API. Paranoia IV, the current development version, is designed to be more flexible, portable and capable. Planned features include parallel port drive support, pregap detection and removal, and NetBSD and Solaris ports. Development seemed to halt some time after 2002, with no public updates to the site and source code for several years, but resumed in August, 2006 ^[1] with the prerelease of version 10.0.

Status indicators

One of the quirks behind cdparanoia is that its ripping status is indicated by a smiley. The following smilies (from the manual of cdparanoia) are used:

:-)        Normal operation, low/no jitter
:-|        Normal operation, considerable jitter
:-/        Read drift
:-P        Unreported loss of streaming in atomic read operation
8-|        Finding read problems at same point during re-read; hard to correct
:-0        SCSI/ATAPI transport error
:-(        Scratch detected
;-(        Gave up trying to perform a correction
8-X        Aborted read due to known, uncorrectable error
:^D        Finished extracting
