JSPatcher, a Visual Programming Environment for Building High-Performance Web Audio Applications

Many visual programming languages (VPLs), which include Max or PureData, provide a graphic canvas for connecting between functions or data. This canvas, also called a patcher, is basically a graph meant to be interpreted as a dataflow computation by the system. Some VPLs are used for multimedia performance or content generation because the user interface system is generally a significant element of the language. This paper presents a Web-based VPL, JSPatcher, which allows users to build audio graphs using the Web Audio API. Users can use aWeb browser to graphically design and run digital signal processor algorithms using domain-specific languages for audio processing, such as FAUST or Gen, and execute them in a dedicated high-priority thread called AudioWorklet. The application can also be utilized to create interactive programs and shareable artworks online with other JavaScript language built-ins, Web APIs, Web-based audio plugins, or external JavaScript modules.
