Beast is a powerful music composition and modular synthesis application. It offers multiple input methods like multitrack, piano roll, and pattern editing and supports skins. On the technical side, it has a wide range of abilities like sequencing, unlimited undo/redo history, real-time synthesis with multiprocessor support, full duplex 32-bit audio rendering, precise timing down to sample granularity, on demand loading of partial wave files, on the fly decoding of various sample formats, aliasing free oscillators, and full Scheme scripting support.
GLAME (GNU/Linux Audio Mechanics) is meant to be the GIMP of audio processing. It is designed to be a powerful, fast, stable, and easily extensible sound editor for Linux and compatible systems. It has full support for non-destructive editing including undo/redo and applying LADSPA effects. Its supported platforms are Linux, BSD, IRIX, and OS X. It uses guile and libxml, and the GNOME libs available is highly recommended. MP3 and Ogg files can be processed if libmad and libvorbisfile are installed.
Siag Office is a free office package which consists of the spreadsheet Siag, the word processor PW, the animation program Egon, the text editor XedPlus, the file manager Xfiler and the previewer Gvu. Siag is easy to use, yet infinitely flexible through multiple embedded interpreters and a plugin mechanism that allows other programs to run inside the main document. The supported interpreters are SIOD, Guile, Tcl, and Python.
jMax is a visual programming environment for building interactive real-time musical and multimedia applications by allowing the user to interactively design dataflow circuits. The basic data types that can go through are integers, symbols, lists, etc. It is an event-driven system and has been used for MIDI processing. A second part of the system (DSP) allows a continuous signal to flow through a circuit, which is most useful for PCM sound (ie. microphone, sound files, etc.). The system is extensible by using shared libraries, you may add data processor types, data types, GUI elements, device types, and more. Data processors may also be designed as circuits and reused.
batchgimp is a batch processor for rendering of images. It uses a command-line interface, and supports JPEG, GIF, PNG, and PSD file formats. It accesses the GNU Image Manipulation Program (GIMP) plug-in structure to provide image processing functions. Images are processed in a batch for an entire directory. batchgimp is written in Perl and interfaces with the Scheme scripting engine provided by the GIMP.
Fluxus is a graphical live coding environment for Scheme. Fluxus reads live audio or OSC network messages which can be used as a source of animation data for real-time performances or installations. Keyboard or mouse input can also be read for simple game development, and a physics engine is included for realtime simulations of rigid body dynamics. The built in scheme code editor runs on top of the renderer, which means you can edit the scripts while they are running.
Halyard is a scriptable multimedia engine with support for video, audio, graphics, and user interaction. It currently runs on Windows, and has a preliminary Macintosh port. It is based on PLT Scheme, wxWidgets, and the Quake 2 Engine. It includes a rudimentary IDE based on Scintilla.
TextureOps is a set of plug-ins for the GIMP related to texture. Compositing a feathered layer on top of another layer slightly reduces the contrast in the the feathered region, noticably modifying the texture. TextureOps contains a "Sharpen Feathering" plug-in to counteract this effect. Also in TextureOps is a modified version of the standard "Make Seamless" plug-in that produces a more uniform result, based on similar principals. Finally, TextureOps provides a simple script for synthesizing a tilable texture of arbitrary size from a sample using the Sharpen Feathering plug-in.
