Cdrdao records audio/data CD-Rs in disk-at-once (DAO) mode based on a textual description of the CD contents (toc-file). Features include full control over length and contents of pre-gaps (pause areas between tracks). Pre-gaps may be completely omitted, e.g. for dividing live recordings into tracks. Control over sub-channel data like catalog numbers, copy, pre-emphasis, 2-/4-channel flags, ISRC code, and index marks are provided as well. GCDMaster is a Gnome GUI front-end that lets you import MP3 and WAV files, select track markers and cut/copy/paste audio snippets before burning.
cdrtools (formerly cdrecord) creates home-burned CDs/DVDs with a CDR/CDRW/DVD/BluRay recorder. It works as a burn engine for several applications. It supports CD/DVD/BD recorders from many different vendors; all SCSI-3/mmc- and ATAPI/mmc-compliant drives should also work. Supported features include IDE/ATAPI, parallel port, and SCSI drives; audio CDs, data CDs, and mixed CDs; full multi-session support; CD-RWs, DVD-R/-RW, DVD+R/+RW, BD-R/BD-RE; and TAO, DAO, RAW, and human-readable error messages. cdrtools includes remote SCSI support and can access local or remote CD/DVD/BD writers.
Disc-cover provides an easy way to produce covers for audio CDs. It scans audio CDs and uses information from the CDDB or CDINDEX database to build a back and front cover for the CD. Output is in Latex, Dvi, PDF, Postscript, HTML, plain ASCII, or any other format suited for cdlabelgen.
gcombust is a CD burner GUI. It works as a GTK+ frontend for mkisofs, mkhybrid, cdrecord, and cdlabelgen. It has primitive support for controlling the directory (root) structure and size of an image without copying files/symlinking or writing 10 lines of arguments. It can also maximize disk usage by hinting at which directories/files to use.
GNU VCDImager is a program for making Video CD (and Super Video CD, a.k.a. SVCD) images out of MPEG movie files. The images it creates are ready to use with programs which understand BIN/CUE images, such as cdrdao. GNU VCDRip allows for reversing the process, ripping mpeg tracks from (Super) Video CDs.
ID3.py is an object-oriented Python module for manipulating the so-called ID3 informational tags on MP3 files, which include such data as artist, track title, genre, et cetera. ID3.py is extremely easy to use, and is intended for folks who are developing MP3 encoder wrapper programs or browsers in Python.
