Open Sound World is a free host application developed by Amar / Open Sound World. Compatible OS(s): Windows, macOS, Linux.
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.
