ChucK is a new (and developing) audio programming language for real-time synthesis, composition, performance, and now, analysis. ChucK presents a new time-based, concurrent programming model that's highly precise and expressive (we 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. Please e-mail me if it works for 64-bit. SOUNDENGINE=jack or SOUNDENGINE=oss to enable jack or oss support: in these cases you will need jack-audio-connection-kit or oss (and the build script will produce a different binary). SOUNDENGINE=alsa is the default.
