Sound for Video Session: What are Impedance and THD and Other Specs?

In this week's sound for video session, I talk through a couple of the specifications you often see listed for microphones, preamps, recorders and such: Impedance & Total Harmonic Distortion. We also talk about impedance bridging and what this means when choosing a microphone, recorder, mixer, or preamp.
