This paper introduces the Audio Plugin Generator (APG), a rapid prototyping tool that allows transforming Simulink models into VST plugins with little effort. VST is a well-known audio plugin interface, supported by a variety of host programs, to process audio signals with low latency. On the other hand, Simulink enables DSP engineers to use clean, human-readable descriptions of their algorithms. The generated plugin supports parameter tuning as well as data logging in real-time. Furthermore, signals can be analyzed inside the plugin with signal scopes. The paper explains the APG workflow and how it bridges the gap between the Simulink Coder and the VST standard. A light version of APG can be obtained free of charge from the APG website: http://audioplugingenerator.com/
