But even before that, you'll want some sort of Faraday cage around the capsule and impedance adapter circuitry. Unless you'll be happy end up with mostly mains & harmonics thereof, instead of useful audio signal.
Only if you intend to connect to a high-impedance input. But even so, expect lots of mains hum/buzz and other interference. And before you ask, no, you do NOT want to use the built-in audio in a laptop or a desktop.
