# __caw__ audio processing program

__caw__ is a declarative language for describing real-time data flow programs
based on the [libcw](https://gitea.currawongproject.org/cml/libcw).

The best introduction to the language is [__caw__ by Example](https://gitea.currawongproject.org/cml/caw/src/branch/master/examples/examples.md)
This tutorial steps through the basic language constructs and theory of operation.
