Simple question, or is it...

Elon is not answering the phone, it looks like when one of his sick Tesla employees cough the pointing vector of the virus changes....

The medium it travels in geoffkait explained above.

, if I’m not mistaken and I don’t think I am, that means the EM wave travels INSIDE the conductor. The E and M fields lie outside the conductor. They are stationary all along the length of the cable or wire. That explains why the type of metal, the purity of the metal and the physical non-symmetries of the metal influence the sound.

@ djones51

If true, kijanki, almarg, herman, Ralph Morrison, and countless other professionals are wrong.

>>>>>I can live with that. Even almarg agrees the signal is an electromagnetic wave that travels at near lightspeed. The E and M fields are not waves. They’re fields. Besides, it’s customary for professionals to not always agree.

Part of the OP’s question:

and what exactly is the medium it travels through in a cable??

The signal energy travels in the space between the wires. Not in the wires.
More precisely through the dielectric insulation covering the wires.

>>>>>The signal energy is not the signal. That’s why the conductor’s physical properties affect the sound. The energy is the E and M fields. The signal is the electromagnetic wave. I thought we already settled that.

Now you are changing the subject.

Subject:

Simple question, or is it...

What exactly is an audio signal made of, and what exactly is the medium it travels through in a cable??

Next you will be changing the subject to fuse directionality.

>>>>>I didn’t change the subject. The simple case of a fuse is a good opportunity or someone to explain the electric signal and how it’s affected by the wire’s physical properties. You can not divorce the cable from the conductor. The fuse is representative of other wires in the audio system. If you feel more comfortable you can use power cord instead of fuse. Pick anything you want. You be the decider. Why dismiss directionality so harshly? Does it make you nervous? All wires are directional. Agree/disagree?
