ChucK – Strongly-timed, Concurrent, and On-the-fly Audio Programming Language
http://chuck.cs.princeton.edu/

ChucK is a new (and developing) audio programming language for real-time synthesis, composition, performance, and now, analysis – fully supported on MacOS X, Windows, and Linux. ChucK presents a new time-based, concurrent programming model that’s highly precise and expressive (they call this strongly-timed), as well as dynamic control rates, and the ability to add and modify code on-the-fly. In addition, ChucK supports MIDI, OSC, HID device, and multi-channel audio. It’s fun and easy to learn, and offers composers, researchers, and performers a powerful programming tool for building and experimenting with complex audio synthesis/analysis programs, and real-time interactive control.
