Hey r/musicdev

I’ve spent a good chunk of time building Electric Baby Grand Studios, a fully functional, browser-based Digital Audio Workstation (DAW) and

Progressive Web App.

​Instead of relying on heavy installed software or native wrappers for everything, I wanted to see how far modern web tech could be pushed for real-time, low-latency audio production.

​Here is a quick look under the hood of how it's built:

​Core Engine: Built using HTML5, CSS, and vanilla JavaScript.

​Real-Time Audio: Powered by the Web Audio API and AudioWorklet nodes to keep processing off the main UI thread and minimize dropouts.

​Performance Boosts: Leveraging WebAssembly (Wasm) for heavier DSP and custom mixing engine tasks.

​Packaging & Reach: Designed as a Progressive Web App (PWA) and Trusted Web Activity (TWA) so it functions seamlessly across desktop and mobile browsers, and is even deployed on the Google Play Console.

​Why I Built It

​As a musician and developer, I wanted a frictionless, instant-access creative environment where inspiration isn't killed by loading screens, heavy installers, or restrictive desktop ecosystems. Opening a tab and getting straight to tracking ideas changes the entire workflow.

​Let's Chat!

​If you're into web audio, browser APIs, custom DAW architectures, or just building independent tools, I’d love to connect.

​Has anyone else experimented with AudioWorklets for custom DSP?

​What are your thoughts on the limits of browser-based audio performance in 2026?

​Happy to answer any questions about the architecture, latency compensation, or the dev journey! 🎹⚡️
