Twin project of WebGL GLSL Shader Editor Extension for Google Chrome

Some more info about this project: WebAudio-Hook demos

Included in the folder wa-hookis the project with the library that instruments a bit more of the AudioContext, and adds interactivty with a few nodes, through DAT.GUI.

How to install

While in beta, you can load the extension from disk directly:

  • Checkout the repo
  • Open Chrome's Extensions page (Settings / More tools / Extensions)
  • Enable Developer Mode
  • Click on Load unpacked extension…
  • Select the folder /src in the checked out project

Alternatively, you can pack the extension yourself and load by dropping the .crx file in the Extensions page.

How to use

  • Browse to a page with Web Audio content (you can find many here, here and here)
  • Open DevTools
  • Select the Web Audio tab
  • The extension needs to instrument AudioContext, so the inspected tab has to be reloaded with the script injected. Hit the Reload button.
  • If there are calls to create nodes and connect them, the UI will show a graph


As always: forks, pull requests and code critiques are welcome!

  • Support all AudioNode types #2
  • Support AudioParam #3
  • Connect panel frontend with Web Audio backend #1

Nice to have:

  • Provide analysis of graph, warnings about unnecessary constructions
  • Store output
  • Live patching


  • v1.0.0 initial release
