Tone Sandbox

Browser-based musical tools and experiments

What is Tone Sandbox?

Tone Sandbox is a collection of open-source interesting, useful, or fun individual musical experiences. The site is designed to allow for anyone to contribute to an existing app or create the own, with goals to provide helpful pre-built functionality to help creative coders focus on what they want to build instead of wrestling with Web Audio APIs and other musical overhead.

In addition, Tone Sandbox is built with Astro, a web framework that lets you build with whatever web technologies or framework you want. Pick from one of a number of supported web frameworks to build what you want with what you're comfortable with.

What have you built so far?

• Piano: Play the piano with either your mouse or a MIDI device. Choose from a variety of instruments, and customize them to suit your needs.
• Fast-Fourier Transform: Visualize the sound from your microphone in real-time. Adjust the sample size or adjust the display scale to better suit your needs.
• Sequencer: Make music with a customizable music sequencer and share it with your friends! Change measure/beat/subdivision lengths, choose your instrument, create short and held notes, and much more.
