# Building Modular Audio Nodes in Web Audio

**[Casey Primozic](https://daily.dev/sources/cprimozic)** · 9 min read · 0 upvotes · 0 comments

## Summary

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.
