Web Audio Api : How do I add a working convolver?

Question

What I am trying to learn / do: How to set up a simple working convolver (reverb) into my code sandbox below using an impulse response. I thought it was similar

Answer 1

Connect the output of the convolver to something. What you have now is the source connected to the convolver, but the convolver isn't connected to anything. As a first cut, convolver.connect(context.destination).
