Audion is a Chrome extension that adds a Web Audio panel to Developer Tools. This panel visualizes the web audio graph in real-time.

How to use:

  1. Install the extension from Chrome Web Store.
  2. Open Chrome Developer Tools. You should be able to find “Web Audio” panel in the top. Select the panel.
  3. Visit or reload a page that uses Web Audio API. If the page is loaded before opening Developer Tools, you need to reload the page for the extension to work correctly.
  4. You can pan and zoom with the mouse and wheel. Click the “autofit” button to fit the graph within the panel.

Had to restart the browser process to make it work. Previously just displayed a box with no audio nodes and I thought it was broken.

Ok, the tool is great but has some bugs, which I'll try to report. Basically it freaked out one of our testers when he installed it and discovered that AudioBufferSourceNodes were piling up and not going away. Indeed the plugin keeps references to all the nodes created and it appears to be impossible to get them to be garbage collected. I just spent several hours convincing myself that it wasn't our code.
