Let's summarize. I am defining the "audio signal" as the very thing that makes the speakers produce sound, I.e., acoustic waves in the room, I.e., music. Some people believe it's the current or voltage. But I already dismissed those answers because they're calculated values, not actually "signals." Some people believe the signal is an electromagnetic wave, in other words photons, propagating through the copper conductor. Others believe the energy contained in the b and e fields associated with the electromagnetic wave that lie outside the copper conductor is the audio signal. So, what do you think the audio signal is?
