morituri is a CD ripper that aims for accuracy over speed. Its features are modeled to compare with Exact Audio Copy on Windows. It features support for MusicBrainz for metadata lookup, support for AccurateRip verification, support for cdparanoia, detection of sample read offset of drives, the ability to test and copy a rip, the ability to detect and rip Hidden Track One Audio, templates for file and directory naming, and tagging using GStreamer. Currently, it only supports lossless encoding and only has a command line client.
SvOlli's Little Audio Related Thingies, or SLART for short, is a compilation of rather simple programs that are related to audio files: it consists of a player (Partyman), a CD ripper, a tag editor, and some other tools. These programs can communicate with each other via a custom IPC bus, so a newly ripped track can be automatically queued in the player, for example.
cdrkit is CD Recording Kit, a collection of applications related to creation of optical disk media on Unix platforms, from creation of the filesystems used on such media to the actual burning process. It is heavily based on the cdrtools package (partially developed and maintained by Joerg Schilling before), but is maintained independently.
RipOff is a GTK+ based CD ripper for Linux (and hopefully for other Unix systems once some testing and fixing have been done) that has a simple interface, CDDB lookups, and a plugin-based encoder architecture. It attempts to appeal to those users who want a non-GNOME dependent CD ripper with a simple interface, or users who just don't like the interfaces of the other GTK+ CD rippers.
FUPlayer is a full featured music manager and player for the GNOME desktop. With it, you can play music from your hard drive, create playlists, do real file management using its Trash, and play, rip, and burn audio CDs. It features an interface similar to those of many modern manager-style players, but with many improvements, such as true non-modal search and browse functionality, find-as-you-type, and drag destination highlighting. It aims to be extremely user friendly and efficient to use.
DaemonRip runs as a Unix daemon and polls a CD drive to see if an audio CD is inserted. When an audio CD is detected, it will automatically connect to a CDDB server to determine the name, artists, and tracks of the CD, and begin to rip and encode the CD using your preferred ripping and encoding applications. When finished ripping the disc, it will be ejected from the drive, allowing you to insert a new one to continue the process. No other user interaction is required. This application also keeps statistics about your ripping and encoding times, and logs all of the actions to a log file.
Max is an application for creating high-quality audio files in various formats from CDs or files. When extracting audio from CDs, it uses cdparanoia. Once the audio is extracted, it can generate audio in over 20 compressed and uncompressed formats including MP3, Ogg Vorbis, FLAC, AAC, Apple Lossless, Speex, AIFF, and WAVE. It can also convert from one format to another. For many popular formats the artist and album metadata is transferred seamlessly between the old and new files. Max is integrated with FreeDB to permit automatic retrieval of CD information. For MP3, FLAC, Ogg FLAC, Ogg Vorbis, AAC, and Apple Lossless files, it will write this metadata to the output.
