[[Concept:Works-with-format]]

AlbumEasy: AlbumEasy generates ready-to-print PDF stamp album pages from a text file containing commands that specify what will appear on the album pages. The software includes comprehensive online help and a text editor with syntax highlighting for the AlbumEasy command set.

Alogg: 'alogg' is a library which makes it easier to use Ogg/Vorbis streams with Allegro. It offers facilities to decode, stream, and encode Ogg/Vorbis streams, and integrates those facilities with Allegro's datafile and sample loading routines. 'alogg' comes with a sample player, streamer, and encoder based on Allegro's sound routines.

Amarok: Amarok is a cross-platform multimedia player that uses the Phonon sound server framework to play audio media and streams, and features a fresh and efficient approach to playlist handling. The emphasis is on the quick and easy user interface, allowing for fast access to the media library.

Ampache: Ampache is a Web-based Audio file manager. It is implemented with MySQL, and PHP. It allows you to view, edit, and play your audio files via the web. It has support for playlists, artist and album views, album art, random play, playback via Http/On the Fly Transcoding and Downsampling, Vote based playback, Mpd and Icecast, Integrated Flash Player, as well as per user themes and song play tracking. You can also Link multiple Ampache servers togeather using XML-RPC. Ampache supports GETTEXT translations and has a full translation of many languages

Aplakons: Aplakons allows you to build a sheets schema to organize activities to be followed by registered users. You can configure sets of sheets to customize each one’s activities to follow. You prepare a repository of sheets (as concrete activities), and after you order them in different arrays. The arrays can be assigned to users as activity plans. For example, a whole diet (array) based on cooking recipes (activities).

Aqualung: Aqualung is an advanced music player originally targeted at the GNU/Linux operating system, today also running on FreeBSD, OpenBSD and other platforms. It plays audio CDs, internet radio streams and podcasts as well as soundfiles in just about any audio format and has the feature of inserting no gaps between adjacent tracks. It also supports high quality sample rate conversion between the file and the output device, when necessary.

Arson: Arson is a KDE frontend to various CD burning and ripping tools. It was originally written to burn audio CDs, as there were no other frontends that used cdrdao (in disk at once mode), that could decode various encoded audio formats (mp3, ogg), and that displayed an accurate track length as the playlist was created. Arson was later expanded to include full progress display for all lengthy operations, audio CD burning, normalization of tracks before burning to even out volumes, data CD burning, CdIndex support (a free CDDB-like service), CD-to-CD copying (direct or with an intermediate file), and audio CD ripping/encoding (ripping tracks from a CD to files), and encoding to WAV, MP3, and Ogg Vorbis formats is supported. Data CD burning and [S]VCD image creation and burning are supported.

Audacious: Audacious is a free software audio player. A descendant of XMMS, Audacious plays your music how you want it, without stealing away your computer’s resources from other tasks. Drag and drop folders and individual song files, search for artists and albums in your entire music library, or create and edit your own custom playlists. Listen to CD’s or stream music from the Internet. Tweak the sound with the graphical equalizer or experiment with LADSPA effects. Enjoy the modern GTK-themed interface or change things up with Winamp Classic skins. Use the plugins included with Audacious to fetch lyrics for your music, to set an alarm in the morning, and more.

Audacity: Audacity is a cross-platform multitrack audio editor that lets you record sounds directly or import Ogg, WAV, AIFF, AU, IRCAM, or MP3 files. It features a few simple effects, all of the editing features you should need, and unlimited undo. The GUI is built with wxWidgets and the audio I/O currently uses PortAudio.

Audio Utils

A collection of bash and perl scripts that help convert audio files.

aac2ogg - a quick and dirty AAC to OGG Vorbis converter.
wma2ogg - simple bash script that uses mplayer to convert ugly WMA files to OGG Vorbis.
reencode - a simple bash script that lets you re-encode MP3 files to higher/lower bitrates. Useful when the resulting MP3 file is going to be on a low-memory device (ie. "MP3" players).

Audio codec 2: 'Audio codec' is part of the LAME project, which is the source code for a fully GPL'd MP3 encoder. The project's goal is to improve the psychoacoustics, noise shaping and speed of MP3.

Autorun: 'autorun' automagically recognizes all available CDROMs in the system, mounts them upon insertion of a media and executes a possible autorun executable on the CD. The user can remove the media; autorun will call unmount after that.

Autotrace: Autotrace is a program which converts bitmap images to vector images. It can import images in BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick, and can output Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk

BRL-CAD: BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.

Bchunk: 'bchunk' converts CD images in the raw BIN/CUE format to a set of tracks in ISO 9660 format, which can be then written on a CD-R using cdrecord. Audio tracks are written in CDR (native CD audio) or WAV format.

Bestfit: Bestfit is a small program to determine which files that should be put on a CD (or other media), so that as little space as possible is wasted. It is very easy to use: you specify files on the command line, and bestfit prints the names of those that were selected. Alternatively, bestfit can execute a command for each selected file (eg. to move them to a different directory).

Biblos: 'Biblos' is a powerful indexing tool for managing a cd/mp3 collection as well as local directories. It records full information about each file on the specified media and has a powerful searching tool that can help you find specific files. You can also select a list of files/dirs from the database and Biblos will help you copy them from the source media to the directory choosen.

BigBlueButton

BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard controls), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboard, and breakout rooms. Presenters can record and playback content for later sharing with others. We designed BigBlueButton for online learning (though it can be used for many other applications). The educational use cases for BigBlueButton are

Online tutoring (one-to-one)
Flipped classrooms (recording content ahead of your session)
Group collaboration (many-to-many)
Online classes (one-to-many)

Blind: blind is a collection of commands for creating and composing new videos as well as editing existing videos. Blind uses a custom raw video format for editing and composing which is very extensible and source control friendly.

BlueSpice: BlueSpice extends MediaWiki and enhances it with useful features, in particular in the areas of quality management, process support, administration, editing and security. There are two editions available: BlueSpice free and BlueSpice pro. BlueSpice free is a free of charge wiki version.
