Open Sound World is a scalable, extensible programming environment that allows musicians, sound designers, and researchers to process sound in response to expressive realtime control.

It combines a familiar visual patching paradigm with solid programming language features such as a strong type system and hierarchical name spaces.

OSW also includes an intuitive model for specifying new components using a graphical interface and high-level C++ expressions, making it easy to develop and share new music and signal processing algorithms.

OSW now includes support for VST instrument and effects plug-ins under Windows, with LADSPA support coming soon.
