A combination of Portal and Sokoban, AdaGate is a great example of OpenGL programming using the Ada language. It is F.O.S., of course.

While exploring a remote south-seas island you make a startling historical discovery. But before you can report your findings, an operational stargate transports you into a curious sequence of dungeons. Your escape will require the logical rearrangement of weird power cells, called Zero Point Modules (ZPMs), that can roll in only two directions.

You can shoot your portal guns at the dungeon walls to define a wormhole. But, in order to activate it, all of the ZPMs must be bumped into their sockets. Now, you can only PUSH the ZPMs. That means you will fail if you roll one into a corner or against a wall.

Escape each level and find your way back to a beautiful lake on the surface.

The degree of difficulty is now selectable. Each game resumes at the beach but progress from previous games is tracked. Complete all 4 levels to access the lake epilog and reset the game.

Uses fully modern OpenGL methods in Ada using textures, shaders and uniforms that achieves version 3.3 core profile contexts in a way that is sufficiently mainstream that it easily compiles and runs on both GNU/Linux and Mac OS-X systems. This project serves as a testbed for learning the complexities of modern OpenGL and GLSL.

Absolutely no coding efforts or compromises have been made to accomodate proprietary operating systems except for learning how to compile on OS-X. It relies on a thin SDL2 binding from Dan Vazquez, a thin OpenGL binding from "Lumen", a PNG reader by Stephen Sanguine, and SFML-Audio.

If one defines "modern" OpenGL to mean version 3.3 or beyond, then this may be the most functionally advanced demonstration of "modern" OpenGL using Ada to be found. The code itself is far from elegant, but serves as a working example, with focus on learning OpenGL. The Ada bindings used are thin, so the relationship to C++ methodology is quite transparent. Developers should note that these Ada bindings are usable as a standalone library for most any OpenGL project.

Media Files Note: The particular choices of sound, image, and shader files (*.fs) delivered are not essential to the function of the game and are easily replaced. This software is primarily intended as a tutorial example of modern OpenGL game assembly methods. The only requirements are that sounds be in WAV format, images be in PNG format, and shaders be updated to GLSL 330 specifications.

Adcd is a CD player for GNU/Linux with a ncurses (text mode) interface. It features all the functions expected in a compact disc player, including playing selected tracks, random playing and loop mode. Also features a non-interactive mode for those who want to play their CDs while using the console for something else.

Advanced GTK+ Sequencer (AGS) is intended to use for music composition.

It features a piano roll, as well a synth, matrix editor, drum machine, soundfont2 player, mixer and an output panel. Further it has LADSPA, DSSI and Lv2 plugin support. It's designed to be highly configurable. You may add effects to its effect chain; and add or remove audio channels/pads. You may set up a fully functional network of engines, thus there is a link editor for linking audio lines. AGS requires a realtime kernel and ALSA support. AGS uses conditional locks to keep several threads in sync that's why you need at least a preemptable kernel.

LADSPA support has been added to version 0.4.2 as well export to WAV.

Version 0.5.x brings you first concurrent audio tree processing support.

Version 0.6.x is dedicated to accessibility. You might control GSequencer by keyboard. As you move to a note it provides you an audible feedback.

Version 0.7.x gives you the benefit of providing the libraries libags, libags-thread, libags-server, libags-audio and libgsequencer. It contains for now an automation editor. Open Sound System (OSS4) and JACK Audio Connection Kit support has been added recently. Now you may configure multiple soundcards. Since 0.7.111 there is MIDI input available. Let you record your MIDI instrument and doing live performance.

Think of a radio station. Airtime is software that allows multiple people to run it over the internet. Airtime helps them manage the audio archive, upload files, create shows, manage staff, edit the programme calendar and cue playout. Designed specifically for independent media, it's free software.

Aria Maestosa
Compose, edit, and play MIDI files. Has a graphical user interface with multiple instrument-specific views.

'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.

'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.

Blocks Of The Undead
Blocks of the Undead is a puzzle game. You have to remove all the blocks on the field by swapping these around.

Bongo is a flexible and usable buffer-oriented media player for GNU Emacs.

'breeze' aims to be a fast and powerful CD Digital-Audio Player. It may run as either a console app or as a daemon. It can control a cdrom that is playing live, can change track to the next or previous one, jcan jump backward or forward, and set a playlist and your information about cdda.
