A simple fade in and out technique with TouchDesigner

I was recently working on a project in TouchDesigner in which I needed to fade in and out background music when a voiceover came on. I tried various solutions at various levels of complexity, but the solution in the end was a really simple one involving use of a filter chop and a math chop. The video above is a little screencast to show how I did it.
