ChucK 是一个并发和强调时间的音频编程语言，主要用于实时声音合成、作曲和表演， 可运行于 OS X、Linux、Microsoft Windows和 iOS。 相比性能等其他因素的考虑，它的设计更注重进程的可读性与编程灵活性。它原生支持 确定性并发 和 同时多重动态控制率。 另外一个关键的功能其对现场编程的支持， 可以在进程不停止或重启的情况下，现场增加、删除和修改进程。它有着非常精确的定时/并发模型，允许任意准确的控制。它为作曲家与研究人员而开发的编程工具兼具强大性能与灵活性，包括对复杂声音合成进行开发和调试，以及实时的交互控制。

ChucK is a concurrent, strongly timed audio programming language for real-time synthesis, composition, and performance, which runs on Linux, Mac OS X, Microsoft Windows, and iOS. It is designed to favor readability and flexibility for the programmer over other considerations such as raw performance. It natively supports deterministic concurrency and multiple, simultaneous, dynamic control rates. Another key feature is the ability to live code; adding, removing, and modifying code on the fly, while the program is running, without stopping or restarting. It has a highly precise timing/concurrency model, allowing for arbitrarily fine granularity. It offers composers and researchers a powerful and flexible programming tool for building and experimenting with complex audio synthesis programs, and real-time interactive control.
