I need some help- I want to capture audio signals from a lavalier mic in a lecture hall. Is there some utility/device that will allow me to capture the signal and interpret it as audio? I would like to use AirPort to do it, but I doubt that will work. If I can find the frequency it transmits on, I may be able to catch it. I doubt that it's encrypted (it's a university lecture). I have access to a respectable variety of high-end journalism equipment, but since I'm going to be doing it mobile, I want to keep this setup small and simple. My equipment is listed below. Any thoughts or comments appreciated New 12" PB G4 512mb 80gb 1.5Ghz 4th gen iPod griffin iTalk various wireless microphones with variable frequencies.
