libburnia is a project comprised of libraries and binaries for reading, mastering, and writing optical discs. It provides libburn, a CD/DVD/BD burn library, libisofs, a manipulation library for ISO 9660 filesystems, and libisoburn, a ISO 9660 multi-session library. On top of them there is cdrskin, a cdrecord emulator, and xorriso, a all-in-one application for ISO 9660 multi-session operations which additionaly provides a limited emulation of mkisofs.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
Python Audio Tools is a collection of audio handling programs that work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more. It supports internationalized track filenames and metadata using Unicode. It works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from MusicBrainz, FreeDB, or compatible servers. Audio formats supported are WAV, FLAC, WavPack, MP3, Ogg Vorbis, M4A, Apple Lossless, and more.
The GNU Compact Disc Input and Control library encapsulates CD-ROM reading and control for applications wishing to be oblivious to the OS- and device-dependent properties of a CD-ROM. It provides an API for access to SCSI-MMC (multimedia commands) and support for CD image types like BIN/CUE, cdrdao's TOC, and Nero's NRG, which gives applications using the library the ability to read disc images as though they were CDs. ISO-9660 filesystem support is included, as are utility programs for displaying CD and CD-ROM drive information, reading the blocks of a CD, and extracting files from an ISO-9660 filesytem image. cdparanoia is also included.
python-musicbrainz2 provides simple, object oriented access to the MusicBrainz Web service. The MusicBrainz Project (see http://musicbrainz.org) provides music metadata maintained by its large and constantly growing user community. This package helps you to write CD ripper applications, taggers, and media players by giving easy access to music metadata.
The CDDB/CDDB_get Perl module gets the CDDB info for an audio CD. The included script was intended as a demo for CDDB_get, but over time it has gained powerful features like the ability to write to a database, offline mode, HTTP mode (including proxy), saving in standard XMCD format, and writing 'lame' commands.
The MusicBrainz client library (also known as mb_client or libmusicbrainz) is a library for developers that wish to add MusicBrainz metadata lookup capabilities to their applications. It calculates CD Index IDs and Relatable's acoustic fingerprints, and looks up the metadata associated with the calculated IDs.
PostScript::CDCover generates a Postscript program that prints a CD cover and backlabel, with contents displayed as a tree of directories and files. The module ships with a stand-alone, ready-to-use script, pscdcover, that takes the directory tree of a CD-ROM as input and generates a cover from it. The output can be directly fed to a PostScript printer, but it is designed to be easily editable (should one wish to remove unwanted directory entries, for example).
