MOC (music on console) is a console audio player for LINUX/UNIX designed to be
powerful and easy to use.
You just need to select a file from some directory using the menu similar to
Midnight Commander, and MOC will start playing all files in this directory
beginning from the chosen file. There is no need to create play lists like in
other players.
If you want to combine some files from one or few directories on one play list,
you can do this. The play list will be remembered between runs or you can save
it as an m3u file to load it whenever you want.
Need the console where MOC is running for more important things? Need to close
the X terminal emulator? You don't have to stop playing - just press q and the
interface will be detached leaving the server running. You can attach it later,
or you can attach one interface in the console, and another in the X terminal
emulator, no need to switch just to play another file.
MOC plays smoothly, regardless of system or I/O load because it uses the output
buffer in a separate thread. It doesn't cause gaps between files, because the
next file to be played is precached while playing the current file.

Internet stream (Icecast, Shoutcast) are supported.
Key mapping can be fully customized.
Supported file formats are: mp3, Ogg Vorbis, FLAC, Musepack, Speex, WAVE, AIFF,
AU (and other less popular formats supported by libsndfile. New formats support
is under development.

Other features:
* Simple mixer.
* Color themes.
* Searching the menu (the play list or a directory) like M-s in Midnight Commander.
* The way MOC creates titles from tags is configurable.
* Optional character set conversion for file tags using iconv().
* OSS, JACK, and ALSA output.

NetCDF (network Common Data Form) is a set of software libraries and
machine-independent data formats that support the creation, access, and sharing
of array-oriented scientific data.
This package provides the old C++ API. It's not recommended for new projects,
but it still works.

This program is an audio-player, written with help of Qt library. The program
has user interface, similar winamp or xmms.

ScummVM is an implementation of the LucasArts SCUMM (Script Creation
Utility for Maniac Mansion) interpreter, used in games such as Monkey
Island and Day of the Tentacle. Some things are still missing in a few
games, and there are a few bugs. Regardless, it is possible to play
some games all the way through to the end.

At the moment there is support for the following games:

Zak McCracken and the Alien Mindbenders (FM Towns version) Loom
(256-color CD version) The Secret of Monkey Island (VGA CD version)
Monkey Island 2: LeChuck's Revenge Indiana Jones and the Fate of
Atlantis (demo and full version) Day of the Tentacle (demo and full
version) Sam & Max (demo and full version) Simon the Sorcerer

There is also experimental support for these games:

Indiana Jones and the Last Crusade (VGA version) The Secret of Monkey
Island (VGA floppy disk version) Full Throttle The DIG

If you are a fan of Sierra On-Line adventure games you might want to
try the 'sarien' and 'freesci' packages.

The Synthesis ToolKit in C++ (STK) is a set of open source audio
signal processing and algorithmic synthesis classes written in the C++
programming language. STK was designed to facilitate rapid development
of music synthesis and audio processing software, with an emphasis on
cross-platform functionality, realtime control, ease of use, and
educational example code. The Synthesis ToolKit is extremely portable
(it's mostly platform-independent C and C++ code), and it's completely
user-extensible (all source included, no unusual libraries, and no
hidden drivers). We like to think that this increases the chances that
our programs will still work in another 5-10 years. In fact, the
ToolKit has been working continuously for about 10 years now. STK
currently runs with realtime support (audio and MIDI) on Linux,
Macintosh OS X, and Windows computer platforms. Generic, non-realtime
support has been tested under NeXTStep, Sun, and other platforms and
should work with any standard C++ compiler.

Aegisub is an advanced subtitle editor for Windows, and UNIX-like systems, such as
Linux, Mac OS X and BSD. It is open source software and free for any use.

Aegisub natively works with the Advanced SubStation Alpha format (aptly abbreviated
ASS) which allows for many advanced effects in the subtitles, apart from just basic
timed text. Aegisub's goal is to support using these advanced functions with ease.

Gavl is short for Gmerlin Audio Video Library. It is a low level library, upon
which multimedia APIs can be built. Gavl handles all the details of audio and
video formats like colorspaces, samplerates, multichannel configurations etc. It
provides standardized definitions for those formats as well as container
structures for carrying audio samples or video images inside an application.

In addition, it handles the sometimes ugly task to convert between all these
formats and provides some elementary operations (copying, scaling, alpha
blending etc).

Kdenlive is a non-linear video editor for GNU/Linux and FreeBSD, which supports
DV, AVCHD (experimental support) and HDV editing. Kdenlive relies on several
other open source projects, such as FFmpeg and the MLT video framework. It was
designed to answer all needs, from basic video editing to semi-professional
work.

libass is a portable subtitle renderer for the ASS/SSA
(Advanced Substation Alpha/Substation Alpha) subtitle
format. It is mostly compatible with VSFilter.

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to
improve headphone listening of stereo audio records. Recommended for headphone
prolonged listening to disable superstereo fatigue without essential
distortions.

libebml is a C++ library to parse EBML files. See the EBML RFV at
http://www.matroska.org/technical/specs/rfc/.

Game_Music_Emu is a collection of video game music file emulators that support
the following formats and systems:

- HES: NEC TurboGrafx-16/PC Engine
- KSS: MSX Home Computer/other Z80 systems (doesn't support FM sound)
- NSF/NSFE: Nintendo NES/Famicom (with VRC 6, Namco 106, and FME-7 sound)
- SAP: Atari systems using POKEY sound chip
- SPC: Super Nintendo/Super Famicom
- VGM/VGZ: Sega Master System/Mark III, Sega Genesis/Mega Drive,BBC Micro

Kate is a codec for karaoke and text encapsulation for Ogg. Most of the
time, this would be multiplexed with audio/video to carry subtitles,
song lyrics (with or without karaoke data), etc, but doesn't have to be.
A possible use of a lone Kate stream would be an e-book. Moreover, the
motion feature gives Kate a powerful means to describe arbitrary curves,
so hand drawing of shapes can be achieved.

This was originally meant for karaoke use, but can be used for any
purpose. Motions can be attached to various semantics, like position,
color, etc, so scrolling or fading text can be defined.

Libmatroska is a C++ library to parse Matroska files (.mkv and .mka).
It depends on libebml to work. You only need this package to compile
your own applications.

MLT is an open source multimedia framework, designed and developed for
television broadcasting. It provides a toolkit for broadcasters, video editors,
media players, transcoders, web streamers and many more types of applications.
The functionality of the system is provided via an assortment of ready to use
tools, XML authoring components, and an extensible plug-in based API.

LV2 is a portable plugin standard for audio systems, similar in scope to LADSPA,
VST, AU, and others. It defines a C API for code and a format for data files
which collectively describe a plugin. LV2 consists of a simple core (roughly
equivalent in power to LADSPA) which can be extended to support more advanced
functionality. This allows the interface to be "grown" to accommodate the needs
of real software as they arise.

LV2 is both a stable interface and a forward-moving project: there is a stable
set of "official" extensions in use while new functionality is actively
developed. Anyone can extend LV2, which allows developers to try out new ideas
and ensure they work in practice. Good extensions are vetted by the community
and included in the official distribution so they can be relied on to be widely
supported. This open development model means developers can always scratch their
itch without a central authority getting in the way. The current stable release
includes most functionality required by modern plugins, including:

* Audio, control, "control voltage" (audio-rate control), and event
(e.g. MIDI) input and output
* Expressive open-ended port metadata, including:
- "Meaningful" controls (e.g. gain or envelope attack) allowing intelligent
host control or UI generation
- Control units (e.g. Hz, octaves, dB)
- Multi-channel port groups (e.g. stereo, 5.1 surround, ambisonics
* Embeddable GUIs in any toolkit, with support for a full plugin/UI split
(including network transparency in capable hosts)
* Ability to bundle any files (e.g. samples or impulses) with plugins
* Presets (bundled and/or user saved)
* Plugin state saving and restoring
* Host-managed logging
* Non-realtime plugin worker methods (simple and portable host-managed
threading)
* Message-based plugin communication, allowing plugins/UIs to have advanced
interfaces without host support or specifications getting in the way
* Transport awareness, both real time and tempo time (bars, beats, etc-.)

LV2 has graceful compatibility "baked in": for example, a simple amplifier
plugin might have audio in/out with a gain control, and function in any host.
The same plugin could have a fancy GUI and transport awareness which optionally
work in hosts that support these features. Conversely, hosts know not to load
plugins that require features it does not support.

See the specification index for complete documentation. If you are a host or
plugin author and need missing functionality, please file a ticket or let us
know your requirements on the mailing list. LV2 is a community project that
depends on your feedback to improve - unknown requirements are unmet
requirements!
