Marsyas is a software framework for building efficient complex audio processing systems and applications. Although originally designed for Music Information Retrieval (MIR) tasks in the past few years it has been expanded to include any type of audio analysis or synthesis. Complex Audio processing systems are defined hierarchically through composition using implicit patching. Both the specification of the processing network and the control of it while data is flowing through can be performed at runtime without requiring recompilation. Compilation is required only when new processing objects need to be defined. Therefore the Marsyas runtime provides considerable functionality and flexibility. In this paper we demonstrate how the Marsyas runtime can be accessed using a variety of different ways allowing non-trivial interactions with common software frameworks and environments.
