How to you create a random sound emitter in wiremod?

[SalletFaff]

I've started using wiremod lately. I've figure out how to wire things like hydraulics and sound emitters so while making a machine I would later dupe I tried to look around to see how I can set up a few sound emitters and at the push of a key have a random one play.
Of course the search came up dry. So how would I be able to make it to where if I set up a dual input and three sound emitters that pressing a key on my keyboard make one of the three sound emitters play at random?
