This repository includes resources & course notes for those attending my Web Audio Synthesis & Visualization workshop with Frontend Masters, demonstrating the raw Web Audio API, p5.js for rendering, and Tone.js for synthesis.

• ✨ Course Demos

• 🔧 Tools

• ✂️️ Code Snippets

• 📖 Setup

• ✨ Further Reading

• 📚 Collections

  • 🔈 web-audio-demos.glitch.me — playback and visualization examples with pure WebAudio

  • 🔈 tone-demos.glitch.me — synthesis and other examples with Tone.js

  • 🎨 p5-demos.glitch.me — examples with p5.js

Here is a list of tools and libraries that will be used during the workshop.

This workshop assumes you are comfortable with JavaScript and ES6 syntax, and instead focuses just on the audio side of things. If you're new to JavaScript, you might want to begin your journey below:

• JavaScript For Cats

Also great is Daniel Shiffman's video series, which often uses p5.js:

• Programming from A to Z

A more comprehensive guide on the JavaScript language can be found here:

• The Modern JavaScript Tutorial

And here's a useful cheat sheet to use as a reference:

• Interactive JavaScript Cheat Sheet

I've also included a small "recipes" document that you can use as a reference if you are forgetting some of the patterns and recipes discussed during the workshop.

• Code Snippets

If you want to run locally (without internet), clone this repo into a new folder, then use Node.js to cd into the folder and run the following to install dependencies:

npm install

Now, start the development server:

npm start

Edit files in src/js and see them reflected in the browser.
