CDDB.py provides an easy way for Python programs to fetch track and disc information on audio CDs. This information is acquired from CDDB, a very large online database of track listings and other information on audio CDs. Included is a C extension module to enable Python to read track listings from audio CDs under Linux, Solaris, FreeBSD, OpenBSD, and Win32. The interface to this extension module is portable and is intended to be ported to other OSes easily.
ova is a convenient console frontend for ripping CDs and encoding MP3 and wave files to the Ogg Vorbis format. It is also able to query the CDDB given a CD (or saved CD discid) or several MP3/Ogg Vorbis/wave files (very useful for downloaded albums). Ogg Vorbis files can be tagged and renamed according to elaborate patterns.
cdlabelgen generates frontcards and traycards for CDs. It was designed to simplify the process of generating labels for CD's. It originated as a program to allow auto generation of frontcards and traycards for CD's burned via an automated mechanism (specifically for archiving data), but has now become popular for labelling CD compilations of mp3's, and copies of CDs as well.
CDR-Toaster is a Tk frontend for writing CDs. It is a graphical front-end for the excelent programs 'mkisofs', 'cdrecord' and 'cdparanoia'. It may be used to burn audio, data, bootable, and combo CDs. It can also rip audio and data tracks. CDR-Toaster can even burn mp3s as audio CDs.
ZoltanPlayer is a music playing daemon. It accepts remote commands via its own mini HTTP server and can seamlessly use Audio or Data CDs. Audio CDs are played internally (optionally querying CDDB info servers) and digital songs in audio CDs are played via external players. It's not limited to CDs, as a hard disk directory can also be used.
make_cd_label is a script that helps create stickers for CDs. It is intended to be integrated with your backup scripts, but can also make stickers for audio CDs using CDDB and disc-cover. The output is an XML file that can be read into glabels and then edited or printed. It uses Memorex or Avery CD label stickers.
