When I give a talk, I generally record the screen, plus there's a video recording of the room. I want to record the voice too, and annoyingly enough, the tiny little radio microphones that people use at conferences typically need a receiver. It's great when a conference has one, but sometimes they don't.
My question: what is the best way to record my own voice? I cannot realistically use a wired mic attached to the laptop b/c I might be moving about the room. I'm thinking maybe Bluetooth or some such? Whatever it is, it needs to be something wearable so I can move about.
