%X OSW, or "Open Sound World," allows development of audio applications using patching, C++, high-level specifications and scripting. In OSW, components called "transforms" are dynamically configured into larger units called "patches."  New components can be expressed using familiar mathematical definitions without deep knowledge of C++. High-level specifications of transforms are created using the "Externalizer," and are compiled and loaded into a running OSW environment. The data used by transforms can have any valid C++ type. OSW uses a reactive real-time scheduler that safely and efficiently handles multiple processors, time sources and synchronous data flows.
