4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.
Allegro is a multi-platform game library for C/C++ developers that provides many functions for graphics, sounds, player input (keyboard, mouse, and joystick), and timers. It also provides fixed and floating point mathematical functions, 3D functions, file management functions, compressed datafile, and a GUI.
AnyChart is a flexible Macromedia Flash-based solution that allows you to create animated, compact, interactive, and attractive charts. Driven by an XML interface, it has no installation and is easily used. There is no need for Active-X on the server since graphics are rendered on the client. All scripting languages (ASP, PHP, ColdFusion, Perl, etc.) are supported. You can easily add your own custom images, sounds, texts, etc.
Anychart Flash Gantt is a customizable component for displaying Gantt charts. Create groups, connectors, and milestones with a simple XML configuration. Driven by an XML interface, it has no installation and is easily implemented. There is no need for Active-X on the server; graphics are rendered on the client. All scripting languages (ASP, PHP, ColdFusion, Perl, etc.) are supported.
The CMU Midi Toolkit (CMT) is a collection of software for writing interactive MIDI software in C. It includes a number of handy utilities along with an application "shell" that provides timing, scheduling, and MIDI interfaces that are portable across DOS, Mac, SGI, and Amiga platforms.
Csound is a powerful and yet easy to use musical synthesis package. Csound was constructed in the tradition of so-called music-N languages, among which the best-known is Music V. It consists of an orchestra- and score-driven executable, written in C for portability. Since Csound is a computational language, it is highly flexible and efficient; complexity is gained only at the expense of computation power. Basically, Csound reads some files and creates the result as a sound file on disk or, on faster machines, in real time through a DAC.
