An overview of the patterns I've developed for building modules for my browser-based DAW and audio synthesis tool.  It outlines solutions for keeping state synchronized between threads, handling async initialization and message passing, and integration with UIs and visualizations.

A deep dive into the architecture patterns used to build modular audio nodes for a browser-based DAW called Web Synth. Covers the core module interface (connectables, serialization, UI rendering), how AudioWorkletProcessors are used for real-time DSP with Rust/Wasm, the async initialization sequence for loading Wasm onto the audio thread, and how SharedArrayBuffer enables efficient live data synchronization between the audio thread and UI thread for visualizations.
