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.
