Castopod: Decentralized podcast hosting software to run on your own server.

Ccd2cue: The program ccd2cue is a CCD sheet to CUE sheet converter for the GNU Operating System. It supports the full extent of CUE sheet format expressiveness, including mixed-mode discs and CD-Text meta-data. It plays an important role for those who need to use optical disc data which is only available in the proprietary sheet format CCD, but don’t want to surrender their freedom. It fills an important gap in the free software world because before its conception it was impossible to use complex forms of optical disc data laid out by CCD sheets in a whole/holy free operating system.

Cdcd: cdcd is a CLI CD player designed to incorporate all the features of the X and curses based CD players without having to use a clunky push button interface or having a console hogged with a curses-based CD player. cdcd can accept commands directly from the command line, or in a query mode similar to telnet or ftp. CDDBP and HTTP mode CDDB support is inlcuded, and now CD Index support as well. cdcd also supports CD-ROM changers on GNU/Linux 2.1 or 2.2 systems. You can run cdcd with a command as the argument (eg cdcd play), which is a great way to use cdcd and cron together to make a CD alarm clock. If you run cdcd without arguments you will be given the cdcd command prompt.

Cdda2wav is a program recording audio tracks digitally (CDDA) from compact disc drives or burners into wav files, making possible lossless copies of audio tracks. It is currently distributed as part of the 'cdrtools' package. Features include:

the ability to record tracks into separate files
the ability to save audio samples in a variety of formats and calculate MD-5 checksums for the sampled data
real-time scheduling (where available)
ability to undo pre-emphasis on-the-fly
can extract title information from CD Extra and CD-Text discs (with appropriate hardware)
can calculate CDDB disc id for title lookups in the internet

Cdparanoia: Cdparanoia is a Compact Disc Digital Audio (CDDA) extraction tool, commonly known as a 'ripper'. It is built on top of the Paranoia library (included in the cdparanoia source distribution). The cdparanoia package reads audio from the CDROM directly as data, with no analog step between, and writes the data to a file or pipe in WAV, AIFC or raw 16 bit linear PCM. 'cdparanoia' contains few-to-no 'extra' features; it concentrates on the ripping process and knowing as much as possible about the hardware performing it. Cdparanoia will read correct audio data from inexpensive drives prone to misalignment, frame jitter and loss of streaming during atomic reads, and can read and repair data from damaged CDs. It has no compile time configuration, and will autodetect the CDROM, its type, its interface and other aspects of the ripping process at runtime.

Cdrdao: 'cdrdao' creates audio or mixed mode CD-Rs in disk-at-once (DAO) mode driven by a description file. In DAO mode, users can create non standard track pre-gaps with lengths other than 2 seconds and contain nonzero audio data. This lets users divide live recordings into tracks where 2 second gaps would be irritating and create hidden tracks or track intros as found on commercial CDs.

Cdrom: Cdrom is a small/lightweight CD-ROM/DVD-ROM drive controlling utility. It supports several features like automatic mounting/unmounting (if needed), speed control, drive capability, CD status, and more. The author notes that cdrom was programmed under Linux 2.4, and has not been tested with newer kernel versions, including the 2.6 branch.

Cdrtools: !!!WARNING!!!! This download probably has serious licence issues. For saver options look at the details tab. cdrtools (formerly cdrecord) creates home-burned CDs with a CDR/CDRW recorder. It works as a burn engine for several applications. It supports CD 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, CDRWs (rewritable), TAO, DAO, RAW, and human-readable error messages. cdrtools includes remote SCSI support and can access local or remote CD writers.

It supports almost all common file formats, SHOUTcast/Icecast streaming, and multiple output plugins. cmus features multiple media library views, a playqueue, a directory browser, powerful filters, and vi-style search and keybindings. The text-only design reduces the resources needed to run the program, making it a strong choice for older or less-powerful computers as well as systems where a graphical environment is not available.

Conversations.im: Conversations is a Jabber/XMPP client for Android 5.0+ smartphones that has been optimized to provide a unique mobile experience. A port to iOS is envisaged in the medium-term future. Conversations allows you to easily send images, show if your contact has received and read your message, permit dynamic history and handles multiple devices (especially sync with desktop clients), allow you to create group chats and support one-to-one Audio/Video calls ! And thanks to the XMPP Protocol (that is a push protocol) you battery life is safe. Conversations also does not require a Google Account or specifically Google Cloud Messaging (GCM). Using the XMPP federated protocol, you can freely choose a trustworthy server (your own if you want) for yourself while still chatting with contacts that are using other servers. The communication between Conversations and the XMPP server as well as the communication between the individual servers is TLS encrypted. This way, not only your messages are safe but more importantly it is impossible for an outside attacker to intercept your meta data (with whom you are chatting) without attacking your server first. On top of that, Conversations gives you the choice to enable one of two end-to-end encryption mechanisms. The first one is OMEMO, a state of the art multi-end-to-multi-end encryption method which is very easy to setup and gives you forward secrecy and plausible deniability. For backwards compatibility reasons Conversations also supports OpenPGP.

Find Duplicate Music Files (fdmf): Find Duplicate Music Files detects music files that contain the same music, even if the files are differently named, and are in different formats such as MP3, OGG, WAV, WMA, M4A, and RealAudio and contain different or non-existent meta-information such as ID3 tags. The program operates on whole directories of music file at a time, or upon multiple directories. It analyzes them and outputs the filenames of pairs that seem similar, based on their audio fingerprint, or perceptual hash.

Flac-jacket: 'flac-jacket' uses raw audio files (raw files are created from data streams) as the source. Based on the filename format, it first creates lossless audio files, using FLAC, and optionally removes the source files if conversion was successful. It then creates a new html page with links to all new and existing .flac files. The html page is regenerated each run, so the listing is somewhat dynamic: you needn't edit the html page just because you removed or renamed a FLAC audio file or altered an artist directory.

Flac2ogg: This is a candidate for deletion: Links broken. No links to page. Email to maintainer broken. Poppy-one (talk) 13:27, 30 July 2018 (EDT) 'flac2ogg' converts FLAC or shorten files to Ogg Vorbis. It retains the FLAC tags as well.

The script is mainly desigend to create Web pages, playlists, and databases for MP3 and Ogg files, but can also used for other purposes. This package was formerly known as 'f2html.'

Mp3splt: 'mp3splt' splits MP3 and Ogg files at specified times without decoding and re-encoding. It's useful for splitting large mp3/ogg to make smaller files or for splitting entire albums to obtain original tracks. You can select split points and filenames manually or you can get them automatically from CDDB (internet or a local file) or from .cue files. It also supports also automatic silence split which can be used also to adjust cddb/cue splitpoints.

Mp3stat: Mp3stat scans MP3 and Ogg files and generates a linear graph of bitrates per section of the file and a table of how many blocks in the file fall under a certain bitrate. It also lets you compare the effect (at least on bitrates) of using different decoders or codecs on the same file as well as seeing how different arguments on the same encoder affect bitrate. The batch file mode lets users compile data about their entire collection.

Mp3station: MP3 STATION is a LIRC-aware, plain-text tool set for managing MP3 playback in a car or home with as little user interaction as possible. It can restart the last playlist at the last played track/frame, transparently load directories and recompile playlists, and keep a repository of all playlists. It has two simple clients for communicating with cm3s (a curses console client and a very basic one on a parallel port). All programs run under a non-privileged user account.

Mp3tools: mp3tools is a set of utilities (mp3id3, mp3info, mp3index, and mp3gui) for managing collections of MPEG audio files. It can get information such as bitrate and play length about a file, view and alter ID3 tags, and generate completely customized listings. mp3info shows the play length, bitrate, MPEG version and layer of an MPEG audio file. mp3id3 shows the ID3 tags from an MPEG audio file and let you change them. mp3index generates customized listings of your MPEG audio files. It comes with a sample "format file", which is how mp3index determines what to make the output look like. The final part of mp3tools is mp3gui, a graphical user interface with all the power of mp3info, and mp3id3 in addition to being a frontend to mp3index. With mp3gui, you don't need to use command-line arguments.

Mp3wrap: 'mp3wrap' wraps two or more mp3 files in one single large playable mp3, without losing filenames and ID3 informations (and without need of decoding/encoding). Also, other non mp3 files (PlayLists, info files, non mp3 files, cover images) may be included inside the mp3. This means you get a large mp3 that you can split in any moment just using mp3splt and in few seconds you have all original files again! It's useful because files created with Mp3Wrap are easy to download. Infact who downloads has not to know each single song name and easy to play and even if you don't have mp3splt to split file, you can listen to it anyway. Mp3Wrap files do not need ID3 to work. It is faster because you have not to select each file one at a time. It can also include path info and other non mp3 files such as playlists.

Mpd: Music Player Daemon (MPD) is a server that allows remote access for playing music (MP3, Ogg Vorbis, and Flac) and managing playlists. The design focus is on integrating a computer into a stereo system that provides control for music playback over a local network. Currently, it includes a Web interface (phpMp), a GTK frontend (gtk2mp), a command line tool (mpc), and a dock app(WMmp). Its goals are ease of installation and use, minimal resource requirements, and stability and flexibility.

Mpd-configure: The mpd-configure bash script creates a valid configuration file for mpd, optimised for bit perfect playback of any digital audio file, including those of high resolution. With default settings the script uses the first available alsa audio interface by using its hardware address (in the form of hw:x,y), and has automagic procedures for things like the music directory and directory where files are stored, the number of items in the music direcory and the UPNP name. When multiple audio interfaces are found, the user is presented with a choice.

Mpd-monitor: `mpd-monitor` is a bash script which displays the properties of an audio stream as played by Music Player Daemon (mpd). Besides the common mpd meta values of the current stream, like title, artist and source (url), it displays the detailed audio properties of the source stream or file, the way mpd interprets it, and the way the stream is handled by alsa (and thereforehanded over to the DAC). It can be used as a real life bit-perfectness monitor.

Mpdired: MPDired is an Emacs front-end (client) for the Music Player Daemon (mdp) with interactions inspired from Dired. It features two views packed into the same interactive buffer: the browser view and the queue view.

Mpv

Music player command: 'mpc' (Music Player Command) is a command-line tool for interfacing Music Player Daemon (MPD). It uses bash tab completion and can use the output of other programs as input via piping. See also: GNU MPC

Mussort: Mussort is a simple music sorting program. It sorts your music (OGG Vorbis/MP3) collection into directories by artist and album, and renames the files themselves.

Mybashburn: MyBashBurn can burn data Cd's, music Cd's, multisession Cd's. It can burn and create ISO files. It can burn bin/cue files, create mp3s, oggs and flac files. Supports burning DVD-images and data DVDs, and other funny options. Also makes use of advanced and extensive regular expressions for the control of the capabilities of backend applications to burn and create audio files. MyBashBurn depends on cdrecord and other backend applications, so basically if your writing device works with it, MyBashBurn will work flawlessly. mybashburn basically, it is no more than a Terminal User Interface (TUI) frontend based of the CD burning shell script called BashBurn for GNU/Linux; this originally does not have the best eye-candy CD-burning UI, nevertheless, MyBashBurn uses dialog boxes/functions which draws (using ncurses) windows onto the screen. MyBashBurn dialog boxes offer good functionality, and has very good capabilities of automatically finding dependencies and auto detecting devices CD/DVD RW. In short, do not reinvent the wheel - just let MyBashBurn do what you want it to do.

This puts Vorbis in the same class as audio representations including MPEG-1, audio layer 3, MPEG-s audio (AAC and TwinVQ) and PAC. Vorbis can both encode and decode as a single pass, real-time stream, and requires roughly the same encoding and decoding power as mp3. We anticipate that it will get faster as time goes on. Ogg vorbis uses the Ogg bitstream format; the correct extension is .ogg. Ogg vorbis was created because mp3 is not truly free: MPEG consortium members claim you cannot create an mp3 encoder without infringing on their patents.

It supports cdparanoia for ripping, BladeEnc, LAME, and GOGO for WAV to MP3 encoding, oggenc for WAV to Ogg Vorbis encoding and CDDB for automatic renaming of MP3 files.

RipOff CD Ripper: RipOff is a GTK+ based CD ripper for GNU/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.

Ripit: 'ripit' is a program for ripping, encoding, and tagging MP3s, and needs no user intervention. It is a wrapper for lame, flac, oggvorbis, dagrab, cdparanoia, and others.

RipperX: RipperX is a GTK program to rip CD audio and encode mp3s. It can rip and encode in parallel and has plugins for cdparanoia, BladeEnc, Lame, GoGo, FHG (l3enc and mp3enc), XingMp3enc, 8hz-mp3, and the ISO encoder. It also has support for CDDB and ID3 tags.

Rockbox: Rockbox is free software replacement firmware for various digital music players. It also runs on top of various operating systems (GNU/Linux, Android) but that is experimental.

Rubyripper: Through multiple times ripping the same track and correcting any differences Rubyripper tries to deliver a secure rip.

SQKshout: 'SQLshout' is a Shoutcast-compatible streaming source client which uses an SQL database as a source for the song information. The goal is to create a shoutcast radio stream that can be interactive with a Web application for voting, weighted playlist generation, and song requests.
