Jeff McCracken created an audio override box and you can too. He says "The goal of this project was to create a little box that would allow me to run several audio inputs into a small box and run one output to my motorcycle helmet. I wanted the audio inputs to be prioritized such that if a higher priority input went active, it would override the current input I was listening to."
