Question: What do I need to know about microphones?

Answer: To the casual observer, it might seem like there’s little to consider when selecting and using a microphone. After all, mic operation is pretty straightforward, isn’t it? You talk or sing or play an instrument into the mic, the mic picks up the sound and transfers it to a speaker or recording device. What’s there to think about?
