Nyquist is an elegant and powerful language for sound synthesis and music composition. Unlike score languages that tend to deal only with events, or signal processing languages that tend to deal only with signals and synthesis, it handles both in a single integrated system. It is also flexible and easy to use because it is based on an interactive Lisp interpreter. You can design instruments by combining functions (much as you would using the orchestra languages of Music V, cmusic, or Csound). You can call upon these instruments and generate a sound just by typing a simple expression. You can combine simple expressions into complex ones to create a whole composition. It runs under any Unix environment, MacOS, Windows 95, and Windows NT, and it produces sound files as output (or direct audio output under Windows).
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.
iVideo is multitrack video editing software, created in Cocoa (Objective-C) and using QuickTime. It was developed for all general video purposes, and to include all of the features of QuickTime Pro and iMovie. It is almost complete; you can import video from digital cameras (using FireWire) or from any QuickTime format supported file, then edit, modify, and mix them, and apply any video effect on or between them. You can then export them to any QuickTime supported format.
Network Auralization for Gnutella (N.A.G.) is an interactive software art tool that turns the process of searching for and downloading MP3 files into a chaotic musical collage. It searches for MP3 files that match keywords on the Gnutella network, and downloads and remixes them in real time based on the structure of the Gnutella network itself. It was commissioned by New Radio and Performing Arts, Inc. and was made possible with funding from the National Endowment for the Arts.
