DSP2JS - A C++ framework for the development of in-browser DSPs
summary
Framework ports C/C++ DSP to the browser by compiling to WebAssembly with Emscripten + WebAudio API and a three-step input: C++ binding class, JSON descriptor, and Makefile. Build produces a JS node file and an audio worklet + WASM processor that handle buffer conversion, runtime profiling and parameter bindings and generates .node and .processor JS files. Live demo builds a custom gain node, runs in the page, responds to parameter changes, and supports an optional bare-build mode for non-WebAudio use.
