libcw is an application framework for developming real-time interactive applications on Linux.

Some of libcw's features are:

• Real-time, low-latency, synchronous and asynchronous interfaces to many common IO devices including:

  • Audio
  • MIDI
  • Serial
  • Sockets
  • Websockets

• Built-in dataflow framework for describing real-time audio and DSP programs.

• A GUI development API and collection of predefined widgets for creating websocket based user interfaces.

• Most elements of the framework are configurable based on configuration files which use an extended JSON syntax.

• The library has minimal dependencies. The only external dependencies are libasound, libwebsockets and libfftw.

• The library implements a large collection of pre-built audio signal processing algorithms.
