Web Audio Test and Live Suite
The Web Audio Test Suite is comprised of performance and benchmark tests for Web Audio. These tests can be run either through Playwright or the Live Suite. Playwright is a browser automation testing framework that runs via CLI or CI. This is useful for automated testing across different browsers or browser versions. Web Audio Test Live Suite is an interactive webpage for running tests locally in your browser and monitoring runtime.
Contributions
My contribution to the Web Audio Test and Live Suite centered around its creation, design, and development with @terryzfeng. After researching between Puppeteer and Playwright, we decided to use Playwright due to its testing capabilities in addition to its browser automation, which we could use for CI.

Rainfly
Rainfly is an Audio Worklet playground, useful for inspecting, developing, and rapid prototyping of Audio Worklet code.
Contributions
Along with @terryzfeng, we created, designed, and developed an MVP of Rainfly using SvelteKit and TailwindCSS.
Documentation

The original MVP hosted on a separate repository due to separate framework and development environment
Rainfly
An AudioWorklet DSP Playground for Chromium Web Audio API Project (2024)
Developing
Install dependencies with npm install (or pnpm install or yarn), and then start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of Rainfly:
npm run build
You can preview the production build with npm run preview.
Introducing Rainfly into web-audio-samples
Rainfly - An AudioWorklet DSP Playground [MVP]
#395
